Small fix for E-AC3 bitstreaming (HDMI)
Remove custom code needed in the past in order to successfully link ffmpeg library.
update CFLAGS and ffmpeg/config.asm and ffmpeg/config.h
update ffmpeg (n0.8-19666-g98c4268)

Notes: broken atm because our custom files need to be updated too.
update h264_recov.c for the recent changes
Fix compilation (not really tested).
