* Clean up extension build mechanism and extension location

* Add back the switch to depend on external sox

* Remove print

* Fix

This PR
 - Changes the location of C++ codes from
     - from `torchaudio/torch_sox.cpp` to `torchaudio/csrc/sox.cpp`
     - from `torchaudio/torch_sox.h` to `torchaudio/csrc/sox.h`
 - Changes the location where the resulting library is placed
     - from `_torch_sox.so` (outside of `torchaudio` module)
        to `torchaudio/_torchaudio.so`.

Fix #628

* [WIP] Add Windows CI

* Remove cu_version

* checkout_merge -> checkout

* Add build script

* Switch backend to soundfile

* Remove soundfile as dependency

* Rename jobs

* Fix lint

* New entry points are packaging/build_wheel.sh and packaging/build_conda.sh. The only mandatory environment variable you have to set is PYTHON_VERSION
* CircleCI configuration uses 2.1-style parametrized builds to let you toggle python version, etc. as you do builds. We create a separate job per build configuration for maximum parallelism
* build_tools/packaging got moved to packaging, to be in-line with directory structure in torchvision
* The build_conda.sh and build_wheel.sh delegate most of the heavy lifting to pkg_helpers.bash, which defines a number of bash functions for performing common operations. The intent is that I'll copy-paste this file between other domain API projects.
* TORCHAUDIO_ prefix removed from envvars, so that I can more easily share packaging scripts between projects
* BUILD_VERSION is completely gone; just change the version number if you need to rebuild
* No more logic for cloning and checking out a fresh copy of torchaudio

Billing of changes:

* Can now toggle what branch is built using BRANCH envvar
* PyTorch nightly we were built against is hardcoded into conda meta.yaml
* Disable Conda Python 3.5 builds as we don't have nightlies for torch at the moment
* No more torchaudio-cpu or torchaudio-nightly suffix
* Remove librosa from testing stanza, so that conda build works with stock anaconda channel
* Change convention on PREFIX to be what we previously called $PREFIX/audio
* Make build_from_source.sh cd-neutral
