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

- Apply __future__ imports uniformly (future division is the biggy, but absolute
  imports mattered too)
- Hotfix use of tempfile.TemporaryDirectory using a BC library (DO NOT
  add this library as a dependency to torchaudio; it's only for testing)
- Replace math.gcd with fractions.gcd
- Fix a weird pytest collection bug involving parametrized tests
- Turn on Python 2 and Python 3.7 in Travis.

* Packaging improvements for nightlies

- Instructions for how to install stable and master binaries,
  without hardcoding wheel filenames
- Turn on Python 2 build (numba is only needed for testing)
- Make builds a little more hermetic
- Prefer building against nightly CPU-only torch build
- Don't install all of requirements.txt, it's not necessary
- Updates for OS X too, including portability issues

This makes it easier to test against an installed wheel, as the
torchaudio folder is no longer preferentially picked up when
you run a test module.

I had to move all tests in subfolders into the top level test
directory to make this work, since you can't access .. modules
without mucking around with sys.path (which I don't want to do.)

NB: this BREAKS the syntax where you can run a test by
saying `python -m test.test`.  Instead, do `python test/test.py`
or use the pytest runner.
