Arch Linux

Description:

There are multiples issue affecting this package:
- `flac` is listed as an optional dependency (it's not, it's a required one)
- `python-discid` is a required dependency (but it's missing)
- `python-pillow` is an optional dependency (but it's missing)
- `python-requests` is listed as required dependency (but it's not used anymore since whipper v0.10.0)

The man pages aren't being built and installed (this is being done in AUR's whipper-git and requires `python-docutils` as make dependency).

Whipper v0.10.0 already includes the changes in `c229c01a5821276de9ee275ccfebe99b51a1a8c8.patch` (not needed anymore).

Issue 515 is currently fixed in v0.10.0 but could appear again in the future (so the `|| ...` may be removed):
```
# https://github.com/whipper-team/whipper/issues/515
PYTHONPATH="build/lib.linux-${CARCH}-${python_version}/" python -m unittest discover || echo "Tests failed"
```

When running the tests against whipper v0.10.0 with ruamel.yaml 0.17.5 (later versions too), a test failure appears which has been fixed in `develop`, check this pull request: https://github.com/whipper-team/whipper/pull/543
