ext/midi: remove all midi stuff borrowed from fluidsynth, now unused
* Create an `m4` directory by hand to avoid:
aclocal-1.11: couldn't open directory `m4': No such file or directory
* Break `econf` out into `src_configure` for EAPI >= 2.
* Don't try and install documentation that no longer exists.
* Other changes to catch up with the trunk's aubio-0.3.2-r2.ebuild.
Use EAPI 3 in aubio ebuild to be unpacker-agnostic.
Oops. Update aubio digest after tweaking keywords.
Restrict the development build of aubio to systems I've tested it on.
Add git-based aubio package (unreleased Python 2.7 fixes in the trunk).
