Merge remote-tracking branch 'qatar/master'

* qatar/master:
  rtmp: Add support for SWFVerification
  api-example: use new video encoding API.
  x86: avcodec: Appropriately name files containing only init functions
  mpegvideo_mmx_template: drop some commented-out cruft
  libavresample: add mix level normalization option
  w32pthreads: Add missing #includes to make header compile standalone
  rtmp: Gracefully ignore _checkbw errors by tracking them
  rtmp: Do not send _checkbw calls as notifications
  prores: interlaced ProRes encoding

Conflicts:
	doc/examples/decoding_encoding.c
	libavcodec/proresenc_kostya.c
	libavcodec/w32pthreads.h
