b00e56bec5 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.

0915b531bc Rename "AVClass class" as "AVClass component_class". 
The aix header math.h defines "extern int class()" for C.
