Summary:
fix https://github.com/pytorch/pytorch/issues/40227
Removed the sorting operation both in ModuleDict class, updated the docstring.
Also remove a sort operation in corresponding unit test, which will lead to unit test fail.
BC Note: Python version after 3.6, the plain dict will preserve the order of keys.
example:
For a python 3.6+ user, if he is initial a ModuleDict instance using plain python dict:
{
"b": torch.nn.MaxPool2d(3),
"a": torch.nn.MaxPool2d(3)
}
, he will get a ModuleDict which preserve the order:
ModuleDict(
(b): MaxPool2d(kernel_size=3, stride=3, padding=0, dilation=1, ceil_mode=False)
(a): MaxPool2d(kernel_size=3, stride=3, padding=0, dilation=1, ceil_mode=False)
)
For a python 3.5 user, if we maintain the same input, then the output ModuleDict could be:
ModuleDict(
(a): MaxPool2d(kernel_size=3, stride=3, padding=0, dilation=1, ceil_mode=False)
(b): MaxPool2d(kernel_size=3, stride=3, padding=0, dilation=1, ceil_mode=False)
)

Just because the annotations are inline doesn't mean the files type
check; most of the newly annotated files have type errors and I
added exclusions for them in mypy.ini. The payoff of moving
all of these modules inline is I can delete the relevant code
generation logic for the pyi files (which was added ignore
annotations that weren't actually relevant anymore.)
For the most part the translation was completely mechanical, but there
were two hairy issues. First, I needed to work around a Python 3.6 and
earlier bug where Generic has a nontrivial metaclass. This fix is in
torch/jit/__init__.py. Second, module.py, we need to apply the same
fix for avoiding contravariance checks that the pyi file used to have;
this is done by declaring forward as a variable (rather than a
function), which appears to be sufficient enough to get mypy to not
contravariantly check input arguments.
Because we aren't actually typechecking these modules in most
cases, it is inevitable that some of these type annotations are wrong.
I slavishly copied the old annotations from the pyi files unless there
was an obvious correction I could make. These annotations will probably
need fixing up later.

Make ModuleList, Sequential, ModuleDict go through the same pathway as other modules, cleaning up a bunch of code and allowing them to define custom forwards and other methods.
EDIT: Previously, we would ignore an nn.Sequential attribute if it was not in `__constants__` ("did you forget to add it to Constants"). This PR scripts it even if it is not in `__constants__`. Is that what we want?

We have `__iter__` defined on nn.ModuleList. Chainer's `Sequential` defines `__iter__`. This will also be helpful in modules which extend `nn.Sequential` and define a custom forward, because they can use the `for x in self` syntax that is supported in both python & TorchScript.

This PR enables users to print extra information of their subclassed nn.Module.
Now I simply insert the user-defined string at the ending of module name, which should be discussed in this PR.
Before this PR, users should redefine the __repr__ and copy&paste the source code from Module.
* Add support for extra information on Module
* Rewrite the repr method of Module
* Fix flake8
* Change the __repr__ to get_extra_repr in Linear
* Fix extra new-line for empty line
* Add test for __repr__ method
* Fix bug of block string indent
* Add indent for multi-line repr test.
* Address review comments
* Update tutorial for creating nn.Module
* Fix flake8, add extra_repr of bilinear
* Refactor DropoutNd
* Change to extra_repr in some Modules
* Fix flake8
* Refactor padding modules
* Refactor pooling module
* Fix typo
* Change to extra_repr
* Fix bug for GroupNorm

Here's the command I used to invoke autopep8 (in parallel!):
git ls-files | grep '\.py$' | xargs -n1 -P`nproc` autopep8 -i
Several rules are ignored in setup.cfg. The goal is to let autopep8
handle everything which it can handle safely, and to disable any rules
which are tricky or controversial to address. We may want to come back
and re-enable some of these rules later, but I'm trying to make this
patch as safe as possible.
Also configures flake8 to match pep8's behavior.
Also configures TravisCI to check the whole project for lint.
The load_state_dict() function now raises an error if the argument
state_dict has extra keys or is missing keys.
Previously, load_state_dict() ignored extra and missing keys, which made
it hard to notice when you load an invalid state_dict. This could
happen, for example, if you save the state_dict for a DataParallel, but
load it into a single model.
The state_dict() function now only includes the Tensor data from the
paramters, which reduces checkpoint size by not saving gradients.
