This is temporary, won't be needed with the new serialization format.
But for now, since the main module gets its name from the archive name,
we need this for safety, other wise something like
`torch.jit.save("torch.pt") will break things.

Summary:
Resubmit #20698 which got messed up.
Idea is that when PyTorch is used in a custom build environment (e.g. Facebook), it's useful to track usage of various APIs centrally. This PR introduces a simple very lightweight mechanism to do so - only first invocation of a trigger point would be logged. This is significantly more lightweight than #18235 and thus we can allow to put logging in e.g. TensorImpl.
Also adds an initial list of trigger points. Trigger points are added in such a way that no static initialization triggers them, i.e. just linking with libtorch.so will not cause any logging. Further suggestions of what to log are welcomed.

Summary:
Adds support for `__getstate__` and `__setstate__` on modules that are called as part of export (`torch.save()`) and import (`torch.jit.load`).
* `__getstate__` and `__setstate__` must be TorchScript functions with the signatures `() -> T` and `(T) -> None` respectively
* The results of `__getstate__` are stored using the pickler in `states.pkl` with one for each module in definition order (`__getstate__` returns `None` by default if an imlpementation is not provided)
* This prevents sharing between `__getstate__` and attributes, but this should be fine since their use is mostly unrelated (attributes are for storing values to be used in script methods, `__getstate__` for running arbitrary computations during import)
Follow up
* Somehow replacing `__getstate__`/`__setstate__` with a `ScriptMethodStub` makes `MyScriptModule().__getstate__()` call `ScriptModule.__getstate__()` when used in Python. This should be fixed so semantics in Python are preserved, but it doesn't affect the typical usage.

If we are namespacing classes, the type parser will need to carry around
some state about which namespaces to look in. This PR just wraps it in a
class in preparation.
Also, subscriptToType can no longer be static, since parseTypeFromExpr
may give different results depending on the namespaces available, so
it's been made a regular function instead of a static map lookup.

Summary:
Allows serialization/loading of attributes (`IValue`s of any type).
* metadata (attribute name, type) is stored in the `model.json`
* The binary format is a subset of the `pickle` module that supports the operations necessary for `IValue`s
* Attributes are serialized in the order they are defined on a module to a list in a single `attributes` file, with submodule attributes coming first. This order directly matches the order attributes are listed in `model.json`
* This can be inspected in Python with `pickle.load()` or with `pickletools` (PyTorch need not be installed for this to work)
* A class is used to store a tensor's index into the tensor table of the model, so to unpickle the file you have to use a custom Unpickler:
```python
class TensorID(object):
def __setstate__(self, id):
self.id = id
class JitUnpickler(pickle.Unpickler):
def find_class(self, module, name):
if module == '__main__' and name == 'TensorID':
return TensorID
JitUnpickler(open("my_model/attributes.pkl", "rb")).load()
```
* pickle format: https://svn.python.org/projects/python/trunk/Lib/pickletools.py
* It currently does not support/guarantee that anything saved out with `pickle` (i.e. if you edit `attributes` with `pickle` directly) instead of our tools will be imported correctly
Also will fix#17683 and fix#16367
Followup Work:
* document format / choice of pickle: #17951
* create an example
* list specializations
* int size specializations, large binputs
* do a first pass over attributes to output only necessary `BINPUT` ops
* attribute reassignment (e.g `self.my_attribute = new_value`)
* `tensor.save("some_checkpoint.pkl")` support with tensors embedded in Pickle file

- I went over each file and fixed up whenever I could tell that clang-format was clobbering comment formatting.
- Made the macros in register_prim_ops a little more clang-format friendly by omitting trailing commas
- Refactored autodiff.cpp to use a helper class with explicit state rather than a bunch of capturing lambdas
- Small improvements to the precommit hook clang-format

Summary:
_th_tensor is moving off Type, so these calls need to be replaced.
Unfortunately, replacing these with a full-fledged solution [e.g. from_storage(..., TensorOptions)] is a bit complicated because the storage itself fully defines the Type (modulo variable). It's simpler to just wait for the Variable/Tensor merge rather than to solve this now, so instead I changed the call sites to: at::empty({0}, type.options()).set_(storage...).
This isn't great because we are also trying to get rid of Type::options, but this seems to be the lesser-of-two-evils.

Summary:
After consulting with Owen, who pointed out the existence of the miniz library, I decided to take one last shot at using zip as our container format.
miniz makes this surprisingly feasible and I think the benefits of using zip are large enough that we should do it.
This replaces our custom container format with a zip archive, preserving all of the
desirable features of our custom format, such as append-oriented writing, and
mmap'able tensor data while adding a bunch of debugging advantages:
1. You can unzip and explore the container to debug what is going on with a model.
2. You can edit the model using a text editor (e.g. change the definition of a method,
or editing the json-serialized meta-data), re-zip the file use OSX's native 'Compress'
option, and re-load the result into pytorch. Note: this enables you to, e.g., print-debug
serialized models.
3. We can easily enable features like compression in the future.
4. Stock python , without pytorch installed, and other programming languages
can reasonably consume this format,using json and zipfile packages, which enables
people to build tools like visualizers without those visualizers depending on pytorch.
This will be especially useful if you want to, for instance, write a visualizer in javascript.
Notes:
* This add miniz (https://github.com/richgel999/miniz) as a dependency. miniz is a self-contained
library for reading/writing zipfiles that unlike other zip libraries also includes libz
compatible compress/decompress support. It is a single header and a single C file without
any other dependencies. Note that the instructions for miniz explicitly state:
> Please use the files from the releases page in your projects. Do not use the git checkout directly!
So we have checked in the 'release' source. Miniz supports zip64, and its API is amenable
to doing zip-align style things to align data.
* Removes 'size' from RecordRef. This allows you to edit files in the zip archive without
editing the meta-data file. Very important if you want to print-debug serialized models.
* PyTorchStreamReader/PyTorchStreamWriter keep mostly the same API (though keys become strings)
However, their implementation is completely swapped out to use miniz.
* Code exists to check for the old magic number to give a decent warning to our preview users
after we change the format.
* Container version information is now put in a stand-alone 'version' file in the archive
and serves a similar purpose to the other container version info.
* All files in the zip archive start at 64-byte boundaries, using an approach similar to
zip-align. Tests check that this property remains true. While the writer does this,
the reader doesn't depend on it, allowing user-created archives that can use compression,
and do not have to align data.
* Added test to check for > 4GB files and archives. Disabled by default because it takes
almost 2 minutes to run.
* torchscript files are now optional: if a submodule does not have methods, it will
not be written.

Summary:
Stacked on https://github.com/pytorch/pytorch/pull/14378, only look at the last commit.
This changes the way methods are defined in TorchScript archives to use
PythonPrint rather than ONNX protobufs.
It also updates torch.proto to directly document the tensor data
structure actually being serialized.
Notes:
* because PythonPrint prints all the methods at once per module, this
removes MethodDef in favor of a single torchscript_area and a separate
caffe2_graphs entry. Note that NetDef's already have method names,
so there is no need or a separate method name entry.
* This switches cpp/pickle area to RecordRef (references to a file in
the container format) since it is possible the data in these arenas
may be large and not suited to json ouput.
* Removes 'annotations' -- annotations should be re-added on the first
commit that actually has a practical use for them. In the current state
it is unlikely they are representing the right information.
* Some expect files have changed because PythonPrint is preserving more
debug name information for parameter names.
* MethodEncoder (the ONNX output format) has been deleted. There is still
some cleanup possible combining EncoderBase and GraphEncode now that there
is only a single pathway using EncoderBase.
* This incorporates the changes from #14397
to define TensorDef
