Summary:
When passing int16 type tensor to `save(backend="sox")`, the resulting file should be 16-bit signed PCM, but instead is 32-bit signed PCM.

Summary:
When saving audio with vorbis, BPS should not be specified, otherwise warnings that cannot be turned off are shown.

std::runtime_error does not preserve the C++ stack trace, so it is unclear to users what went wrong internally.

PyTorch's TORCH_CHECK macro allows to print C++ stack trace when TORCH_SHOW_CPP_STACKTRACES environment variable is set to 1.

This PR moves the code related to PyBind11 to the dedicated directory `torchaudio/csrc/pybind`.

Before, features related to PyBind11 (I/O for file-like object) was implemented in `torchaudio/csrc/sox` and the binding was defined in `torchaudio/csrc/pybind.cpp`. We used macro definition `TORCH_API_INCLUDE_EXTENSION_H` to turn on/off the feature, in addition to including/excluding `torchaudio/csrc/pybind.cpp` in the list of compiled source.

In the previous manner, in C++ example, one had to rebuild libtorchaudio separately, but by splitting them completely at compile time, it should conceptually possible to distribute libtorchaudio within torchaudio Python package and reuse it for C++ example.

Some audio formats like `gsm` does not have valid frame numbers when opened. But `libsox` can properly handle these audios, so checking if `length > 0` is not necessary and too strict.

After a9f5e7229 was merged into upstream pytorch the passing of
references within torch c extension functions is no longer allowed. This
just removes the reference and passes by value instead.

This is a part of PRs to add new "sox_io" backend. #726 and depends on #718, #728 and #731.

This PR adds `save` function to "sox_io" backend, which can save Tensor to a file with the following audio formats;
 - `wav`
 - `mp3`
 - `flac`
 - `ogg/vorbis`

This is a part of PRs to add new "sox_io" backend. #726 and depends on #718 and #728 .

This PR adds `load` function to "sox_io" backend, which is  tested on the following audio formats;
 - `wav`
 - `mp3`
 - `flac`
 - `ogg/vorbis` *

By default, "sox_io" backend returns Tensor with `float32` dtype and the shape of `[channel, time]`. The samples are normalized to fit in the range of `[-1.0, 1.0]`.

Unlike existing "sox" backend, the new `load` function can handle WAV file natively, when the input format is WAV with integer type, (such as 32-bit signed integer, 16-bit signed integer and 8-bit unsigned integer) by providing `normalize=False`, this function can return integer Tensor, where the samples are expressed within the whole range of the corresponding dtype, that is, `int32` tensor for `32-bit PCM`, `int16` for `16-bit PCM` and `uint8` for `8-bit PCM`. This behavior follows [scipy.io.wavfile.read](https://docs.scipy.org/doc/scipy/reference/generated/scipy.io.wavfile.read.html). `normalize` parameter has no effect for other formats and the load function always return normalized value with `float32` Tensor.

__* Note__ The current binary distribution of torchaudio does not contain `ogg/vorbis` and `opus` codecs. To handle these files, one needs to build torchaudio from the source with proper codecs in the system.

__Note 2__ Since this PR, `scipy` becomes required module for running test.
