Michael Niedermayer 484aec4da3 LICENSE: correct incorrect claims on *GPL incompatibility
There are currently no statements from any person qualified in the art
of law about the LGPL compatibility of the libfaac license and others.
Furthermore their is no consensus about their compatibility amongth
people not qualified in the art.

Also of interrest may be that ubuntu distributes and links libfaac
to LGPL code. And the ubuntu technical comittee decision about libfaac
https://lists.ubuntu.com/archives/technical-board/2011-February/000703.html

Comments and other viewpoints, especially if i have missed something
are very welcome!

Mans Rullgard ec7c501ed5 x86: remove libmpeg2 mmx(ext) idct functions
These functions are not faster than other mmx implementations on
any hardware I have been able to test on, and they are horribly
inaccurate.  There is thus no reason to ever use them.

Diego Biurrun b315042c8c Remove libpostproc.
This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.
