Merge remote-tracking branch 'cehoyos/master'

* cehoyos/master:
  Support compilation on aix with gcc.
  Rename "AVClass class" as "AVClass component_class".
  Rename constant FRAMESIZE in ra144 codec as FRAME_SIZE.
  Rename thread_init() in libavcodec and libavfilter as library_thread_init().
  Rename constant HZ in af_biquads.c as HERTZ.
  Drop local lable from ppc asm timer.
