ffmpeg: add a recipe, and remove the libav recipe

The reasons for the switch are here:
http://lists.openembedded.org/pipermail/openembedded-core/2015-July/107091.html
http://lists.openembedded.org/pipermail/openembedded-core/2016-January/116007.html

Changes made to libav recipe:
- drop libav-fix-CVE-2014-9676.patch, the fix is available upstream
- merge .inc into .bb, only one upstream version (latest one) is provided
- drop separate libpostproc recipe, the library is provided directly
from ffmpeg source tree
- drop ARM tweaks; they date to classic-OE, need to be retested against the
new code and probably haven't been relevant for a long time
- drop PACKAGECONFIG options that are no longer provided upstream
- drop build and packaging tweaks that don't seem to do anything useful
and also date back to classic OE; if you run into issues, please report
- explicitly enable PIC and disable stripping of binaries

-Subject: [PATCH] segment: Fix the failure paths
-
-A failure in segment_end() or segment_start() would lead to freeing
-a dangling pointer and in general further calls to seg_write_packet()
-or to seg_write_trailer() would have the same faulty behaviour.
