Dropping allowMidside breaks nearly all library consumers

[ephemeralriggs]

In commit 12d7414 the struct member allowMidside is dropped from faacEncConfiguration.

This breaks the build on virtually every consumer of libfaac. Due to the history of AAC in open source projects, many of those consumers are not frequently updated anymore.
For example, in FreeBSD we keep a (no longer maintained) package of ffmpeg before 1.0 around in order to support other infrequently maintained packages. This old ffmpeg package (and quite a few more, obviously) expect allowMidside.

Would it be possible to stay backward compatible for a certain grace period and keep the struct member allowMidside for now? This would allow the community to come up with the necessary workarounds in a release-friendly manner.

A trivial patch to all those packages: just don't set allowMidside and you're OK.

Thanks! Easy enough :-)

@riggs- good news: backwards compatibility was restored as of 1.29.9.2 thanks to @enzo1982 and @knik0
