Follow up from https://github.com/pytorch/pytorch/issues/45419, in
this PR I've removed as many PyCFunction casts as I could from the codebase.
The only ones I didn't remove were the ones with `METH_VARARGS | METH_KEYWORDS`
which have 3 parameters instead of 2 and had to be casted. Example: `
{"copy_", (PyCFunction)(void(*)(void))THPStorage_(copy_), METH_VARARGS |
METH_KEYWORDS, nullptr},`

- What does the generated binding code do?
The Python binding codegen produces code that takes the input list of
PyObjects, finds the matching ATen C++ function using PythonArgParser,
converts the PyObjects into C++ types and calls the ATen C++ function:
```
+--------+ parsing +------------------------+ binding +-----------------------+
| PyObjs | ---------> | PythonArgParser Output | ---------> | Cpp Function Dispatch |
+--------+ +------------------------+ +-----------------------+
```
- Are Python arguments 1-1 mapped to C++ arguments?
Python arguments might be reordered, packed, unpacked when binding to
C++ arguments, as illustrated below:
```
// Binding - Reorder & Packing
// aten::empty.names(int[] size, *, Dimname[]? names, ScalarType? dtype=None, Layout? layout=None,
Device? device=None, bool? pin_memory=None, MemoryFormat? memory_format=None) -> Tensor
Python Args Cpp Args
-----------------------------------------------------------
0: size size
1: names names
2: memory_format -------+
3: dtype -----+-|--> options
4: layout / |
5: device / +--> memory_format
6: pin_memory /
7: requires_grad -+
// Binding - Unpacking
// aten::max.names_dim(Tensor self, Dimname dim, bool keepdim=False) -> (Tensor values, Tensor indices)
Python Args Cpp Args
-----------------------------------------------------------
+----> max
/-----> max_values
0: input / self
1: dim / dim
2: keepdim / keepdim
3: out -----+
```
- Why do we want to rewrite the python binding codegen?
The old codegen takes Declarations.yaml as input. It doesn't distinguish
between Python arguments and C++ arguments - they are all mixed together
as a bag of non-typed dict objects. Different methods process these arg
objects and add new attributes for various different purposes. It's not so
obvious to figure out the semantics of these attributes. The complicated
binding logic happens implicitly and scatteredly.
```
+--------------------+
| Native Functions |
+--------------------+
|
|
v
+--------------------+
| Cpp Signatures |
+--------------------+
|
|

| Declarations.yaml |

+--------------------+ +-------------------------------------+
| .
| .
| .
| +-------------------------------------+
+-------> | Cpp Function Dispatch |
+-------------------------------------+
```
This PR leverages the new immutable data models introduced in the new
aten codegen. It introduces dedicated data models for python schema.
This way, we can not only avoid subtle Declaration.yaml conversions but
also decouple the generation of python schema, python to c++ binding and
c++ function call.
The ultimate state will be like the following diagram:
```
+-------------------+ +-------------------------------------+
+-------> | Python Signatures | --> | PythonArgParser Schema |

```
This PR has migrated the core binding logic from
tools/autograd/gen_python_functions.py to tools/codegen/api/python.py.
It produces the byte-for-byte same results (tested with #46243).
Will migrate the rest of gen_python_functions.py in subsequent PRs.

How to approach reviewing this diff:
- The new codegen itself lives in `tools/codegen`. Start with `gen.py`, then read `model.py` and them the `api/` folder. The comments at the top of the files describe what is going on. The CLI interface of the new codegen is similar to the old one, but (1) it is no longer necessary to explicitly specify cwrap inputs (and now we will error if you do so) and (2) the default settings for source and install dir are much better; to the extent that if you run the codegen from the root source directory as just `python -m tools.codegen.gen`, something reasonable will happen.
- The old codegen is (nearly) entirely deleted; every Python file in `aten/src/ATen` was deleted except for `common_with_cwrap.py`, which now permanently finds its home in `tools/shared/cwrap_common.py` (previously cmake copied the file there), and `code_template.py`, which now lives in `tools/codegen/code_template.py`. We remove the copying logic for `common_with_cwrap.py`.
- All of the inputs to the old codegen are deleted.
- Build rules now have to be adjusted to not refer to files that no longer exist, and to abide by the (slightly modified) CLI.
- LegacyTHFunctions files have been generated and checked in. We expect these to be deleted as these final functions get ported to ATen. The deletion process is straightforward; just delete the functions of the ones you are porting. There are 39 more functions left to port.

Summary:
This PR adds the `torch.linalg` namespace as part of our continued effort to be more compatible with NumPy. The namespace is tested by adding a single function, `torch.linalg.outer`, and testing it in a new test suite, test_linalg.py. It follows the same pattern that https://github.com/pytorch/pytorch/pull/41911, which added the `torch.fft` namespace, did.
Future PRs will likely:
- add more functions to torch.linalg
- expand the testing done in test_linalg.py, including legacy functions, like torch.ger
- deprecate existing linalg functions outside of `torch.linalg` in preference to the new namespace

Summary:
This PR creates a new namespace, torch.fft (torch::fft) and puts a single function, fft, in it. This function is analogous to is a simplified version of NumPy's [numpy.fft.fft](https://numpy.org/doc/1.18/reference/generated/numpy.fft.fft.html?highlight=fft#numpy.fft.fft) that accepts no optional arguments. It is intended to demonstrate how to add and document functions in the namespace, and is not intended to deprecate the existing torch.fft function.
Adding this namespace was complicated by the existence of the torch.fft function in Python. Creating a torch.fft Python module makes this name ambiguous: does it refer to a function or module? If the JIT didn't exist, a solution to this problem would have been to make torch.fft refer to a callable class that mimicked both the function and module. The JIT, however, cannot understand this pattern. As a workaround it's required to explicitly `import torch.fft` to access the torch.fft.fft function in Python:
```
import torch.fft
t = torch.randn(128, dtype=torch.cdouble)
torch.fft.fft(t)
```
See https://github.com/pytorch/pytorch/issues/42175 for future work. Another possible future PR is to get the JIT to understand torch.fft as a callable class so it need not be imported explicitly to be used.

Summary:
According to pytorch/rfcs#3
From the goals in the RFC:
1. Support subclassing `torch.Tensor` in Python (done here)
2. Preserve `torch.Tensor` subclasses when calling `torch` functions on them (done here)
3. Use the PyTorch API with `torch.Tensor`-like objects that are _not_ `torch.Tensor`
subclasses (done in https://github.com/pytorch/pytorch/issues/30730)
4. Preserve `torch.Tensor` subclasses when calling `torch.Tensor` methods. (done here)
5. Propagating subclass instances correctly also with operators, using
views/slices/indexing/etc. (done here)
6. Preserve subclass attributes when using methods or views/slices/indexing. (done here)
7. A way to insert code that operates on both functions and methods uniformly
(so we can write a single function that overrides all operators). (done here)
8. The ability to give external libraries a way to also define
functions/methods that follow the `__torch_function__` protocol. (will be addressed in a separate PR)
This PR makes the following changes:
1. Adds the `self` argument to the arg parser.
2. Dispatches on `self` as well if `self` is not `nullptr`.
3. Adds a `torch._C.DisableTorchFunction` context manager to disable `__torch_function__`.
4. Adds a `torch::torch_function_enabled()` and `torch._C._torch_function_enabled()` to check the state of `__torch_function__`.
5. Dispatches all `torch._C.TensorBase` and `torch.Tensor` methods via `__torch_function__`.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/41947
Previously, if an op took an optional `Tensor?` argument, the C++ frontend (i.e. `at::op()` and `Tensor::op()`)
were generated to take `Tensor`. A previous PR (https://github.com/pytorch/pytorch/pull/41610) changed the kernels
to be written with `c10::optional<Tensor>` instead of `Tensor`, but that did not touch the C++ frontend yet.
This PR changes the C++ frontend API to take `c10::optional<Tensor>` instead of `Tensor` as well.
This should be mostly bc conserving. Since `Tensor` implicitly converts to `c10::optional<Tensor>`, any old code
calling an op with a `Tensor` would still work. There are likely corner cases that get broken though.
For example, C++ only ever does *one* implicit conversion. So if you call an op with a non-tensor object
that gets implicitly converted to a `Tensor`, then that previously worked since the API took a `Tensor` and
C++ allows one implicit conversion. Now it wouldn't work anymore because it would require two implicit conversions
(to `Tensor` and then to `c10::optional<Tensor>`) and C++ doesn't do that.
The main reasons for doing this are
- Make the C++ API more sane. Those arguments are optional and that should be visible from the signature.
- Allow easier integration for XLA and Autocast. Those backends generate code to wrap operators and forward
operator arguments to calls to at::op(). After https://github.com/pytorch/pytorch/pull/41610, there was
a mismatch because they had to implement operators with `optional<Tensor>` but call `at::op()` with `Tensor`,
so they had to manually convert between those. After this PR, they can just forward the `optional<Tensor>`
in their call to `at::op()`.

Summary:
Per title.
Currently torch.full will always (attempt to) produce a float tensor. This is inconsistent with NumPy in (at least) two cases:
- When integral fill values (including bool) are given
- When complex fill values are given
For example:
```
np.full((1, 2), 1).dtype
: dtype('int64')
np.full((1, 2), (1 + 1j)).dtype
: dtype('complex128')
```
Whereas in PyTorch
```
torch.full((1, 2), 1).dtype
: torch.float32
torch.full((1, 2), (1 + 1j)).dtype
: RuntimeError: value cannot be converted to type float without overflow: (1,1)
```
This PR begins the process of deprecating our current behavior of returning float tensors (by default) when given integer fill values by warning the user that integer fill values will require explicitly specifying the dtype or out kwargs in 1.6, and in 1.7 the behavior will change to return a LongTensor by default (BoolTensor for bool values). The intermediate 1.6 release is to prevent changing the behavior silently and unexpectedly.
The PR also implements inference for complex types. So that with it:
```
torch.full((1, 2), (1 + 1j)).dtype
: torch.complex64
```
The complex type inference returns a ComplexFloat tensor when given a complex fill value (and no dtype or out kwarg is specified), unless the default dtype is Double, in which case a ComplexDouble tensor is returned.
A test for these behaviors is added to test_torch.py.
Implementation note:
This PR required customizing full's dispatch because currently in eager codegen the TensorOptions object passed to functions improperly sets has_dtype() to true, even if the user did not explicitly provide a dtype. torch.arange already worked around this issue with its own custom implementation. The JIT, however, does pass a properly constructed TensorOptions object.
Future Work:
This PR does not extend torch.full's complex type inference to ONNX. This seems unlikely to come up and will be a clear error if it does. When integer type inference is added to torch.full, however, then porting the behavior to ONNX may be warranted. torch.arange ported its complex type promotion logic to ONNX, for example.
Additionally, this PR mostly leaves existing call sites in PyTorch that would trigger this warning intact. This is to be more minimal (since the PR is BC breaking). I will submit a separate PR fixing PyTorch's call sites.

Summary:
This adds `__torch_function__` support for all functions in `torch.functional` and `torch.nn.functional`.
The changes to C++ code and codegen scripts are to facilitate adding `__torch_function__` support for the native functions in `torch._C._nn`. Note that I moved the `handle_torch_function` C++ function to a header that both `python_torch_functions.cpp` and `python_nn_functions.cpp` include. The changes to `python_nn_functions.cpp` mirror the changes I made to `python_torch_functions.cpp` when `__torch_function__` support was first added in https://github.com/pytorch/pytorch/issues/27064. Due to the somewhat different way the `torch._C` and `torch._C._nn` namespaces are initialized I needed to create a new static reference to the `torch._C._nn` namespace (`THPNNVariableFunctions`). I'm not sure if that is the best way to do this. In principle I could import these namespaces in each kernel and avoid the global variable but that would have a runtime cost.
I added `__torch_function__` support to the Python functions in `torch.nn.functional` following the approach in https://github.com/pytorch/pytorch/issues/32194.
I re-enabled the test that checks if all functions in the `torch` namespace are explicitly tested for `__torch_function__` support. I also generalized the check to work for `torch.functional` and `torch.nn.functional` as well. This test was explicitly disabled in https://github.com/pytorch/pytorch/issues/30730 and I'm happy to disable it again if you think that's appropriate. I figured now was as good a time as any to try to re-enable it.
Finally I adjusted the existing torch API tests to suppress deprecation warnings and add keyword arguments used by some of the code in `torch.nn.functional` that were missed when I originally added the tests in https://github.com/pytorch/pytorch/issues/27064.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/33305
The current TensorOptions code is written to exactly extract out
TensorOptions based on exact struct match, including default arguments.
That meant that tril_indices/triu_indices which had a different
default argument didn't match, and thus needed a special case.
I resolve this special case by instead replacing the explicit long
default argument with a None default argument, and then adjusting
the actual implementations to select the correct dtype when none
was specified. I think the general rule I'm following here is that
it is always acceptable to replace an explicit default argument,
with a None argument (assuming the backend will compute it appropriately);
the documentation gets modestly worse, but everything that was
previously expressible continues to be expressible. Maybe later
we should switch the default argument back to long, but for now
the simplification in code is worth it.

[codegen diff](https://github.com/bhosmer/scratch/compare/deprecation_warning_before...deprecation_warning_after)
More important than the size savings is the minimization of codegen. Ideally the generated artifact should express distinctive per-op properties in as minimal a form as practically possible - e.g. here instead of generating check-and-warn behavior into every binding, we generate only the data that triggers the behavior in the parser. (And actually we were generating it already.)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/29986
Previously in addition to generating a python binding for each op,
we would generate an almost-trivial helper for each overload.
This PR eliminates the helpers, simplifying codegen logic a bit and
reducing the source-level indirection by a step.
Perf should be unchanged.

Note: in the interests of keeping the diff contained, there's only
some light cleanup here beyond what's necessary for the codegen changes.
Plan is to do some more substantial refactoring in followup PRs that
leave generated code unchanged.

Summary:
Fixes https://github.com/pytorch/pytorch/issues/28430
The unpythonic signatures for functions such as `torch.addcdiv` are already seperated in [`deprecated.yaml`] and the signatures marked as deprecated in `PythonArgParser`. However, nothing was done with this information previously. So, this now emits a warning when the deprecated signatures are used.
One minor complication is that if all arguments are passed as keyword args then there is nothing to differentiate the deprecated overload. This can lead to false warnings being emitted. So, I've also modified `PythonArgParser` to prefer non-deprecated signatures.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/31517
This is going to be used by upsample (which currently uses magic values to represent optionals).
For now, we just introduce a fake function for testing (torch._test_optional_float(x)).

Fixes https://github.com/pytorch/pytorch/issues/29161.
I looked a bit at the code changes related to this and think I have all of the use cases of `DeprecatedTypeProperties` covered in the message, but suggestions from someone with more context on this would be very much appreciated :)

Summary:
This is a re-do of https://github.com/pytorch/pytorch/issues/27064, which was reverted (b8792c0438). This was landed at the same time as other work that added new operators to the `torch` namespace so the check for whether the `torch` namespace is exhaustively checked for overridability was triggering test failures.
I've temporarily disabled that check and added an explanatory comment that the check will be re-enabled in a future PR that will be merged during a time when the commit velocity on PyTorch is lower.
