Summary:
Symbols are given hidden visibility by default on Linux to emulate the behavior on Windows. This helps developers catch visibility issues in their streamlined Linux dev environment before being surprised, late in the process, by Windows errors.

Summary:
First time this was merged it broke master and was reverted. This time I do not add ```set -u``` to the .circleci/scripts/setup* scripts. There's still a chance that ```set -u``` breaks the binary builds on master, but at least those can be fixed in parallel and don't completely eliminate signal from all merges.

Summary:
We don't need to overlay vc env when not using ninja. CMake will deal with it automatically. Overlaying is a no-op when the env is the same with the generator specified but will generate the error "Cannot find CMAKE_CXX_COMPILER" when they are different.

Summary:
This PR is an intermediate step toward the ultimate goal of eliminating "caffe2" in favor of "torch". This PR moves all of the files that had constituted "libtorch.so" into the "libcaffe2.so" library, and wraps "libcaffe2.so" with a shell library named "libtorch.so". This means that, for now, `caffe2/CMakeLists.txt` becomes a lot bigger, and `torch/CMakeLists.txt` becomes smaller.
The torch Python bindings (`torch_python.so`) still remain in `torch/CMakeLists.txt`.
The follow-up to this PR will rename references to `caffe2` to `torch`, and flatten the shell into one library.

Summary:
`scripts/build_windows.bat` is the original way to build caffe2 on Windows, but since it is merged into libtorch, the build scripts should be unified because they actually do the same thing except there are some different flags.
The follow-up is to add the tests. Looks like the CI job for caffe2 windows is defined [here](https://github.com/pytorch/ossci-job-dsl/blob/master/src/jobs/caffe2.groovy#L906). Could we make them a separate file, just like what we've done in `.jenkins/pytorch/win-build.sh`? There's a bunch of things we can do there, like using ninja and sccache to accelerate build.

* **#18598 Turn on F401: Unused import warning.**
This was requested by someone at Facebook; this lint is turned
on for Facebook by default. "Sure, why not."
I had to noqa a number of imports in __init__. Hypothetically
we're supposed to use __all__ in this case, but I was too lazy
to fix it. Left for future work.
Be careful! flake8-2 and flake8-3 behave differently with
respect to import resolution for # type: comments. flake8-3 will
report an import unused; flake8-2 will not. For now, I just
noqa'd all these sites.
All the changes were done by hand.

Summary:
With this patch you can use USE_DISTRIBUTED=OFF (possibly in combination with USE_NCCL=OFF (?))
The significance is partly because the NCCL doesn't build with CUDA 8.
This is written under the assumption that NCCL is required for distributed if not, the USE_DISTRIBUTED check in nccl.py should be replaced by a check for the USE_NCCL environment variable.

Summary:
This PR fixes following issue: https://github.com/pytorch/pytorch/issues/16828
It is a combination of two things:
1) MKLDNN streams are not thread-safe but are currently shared between different threads. This change makes them thread_local
2) By default MKLDNN primitives can share global memory and can't be invoked from multiple threads. This PR enables the MKLDNN_ENABLE_CONCURRENT_EXEC cmake configuration option that makes them thread-safe.

We inadvertently switch the OSX build over to ninja on CI. It then fails to respect MAX_JOBS and hits the same scache deadlock bug, this makes the ninja build respect MAX_JOBS.

Rehash of previous attempts. This tries a different approach where we accept the install as specified in cmake (leaving bin/ include/ and lib/ alone), and then try to adjust the rest of the files to this more standard layout.

Also, because sometimes we have `CMakeCache.txt` but cmake errored out so I'm adding the existence of `'build.ninja'` as another criterion of rerunning cmake.

Summary:
This commit removes the dependency on `build_pytorch_libs.sh` by moving the remaining functionality that is not expressible in cmake into python. Removing the indirection through bash also removes over 300 lines of environment munging code that is incredibly hard to understand because it passes a lot of secret parameters through `os.env`.
