  h264: new assembly version of get_cabac for x86_64 with PIC
  h264: use one table instead of several for cabac functions
  h264: (trivial) remove unneeded macro argument in x86/cabac.h
  libschroedingerdec: check malloc
  segment: reorder seg_write_header allocation
  avio: make avio_close(NULL) a no-op
  mov: Parse EC3SpecificBox (dec3 atom).

Conflicts:
	libavcodec/cabac.c
	libavcodec/x86/cabac.h
