Merge remote-tracking branch 'qatar/master'

* qatar/master:
  ARM: remove MULL inline asm
  mathops: use MUL64 macro where it forms part of other ops
  tty: factorise returning error codes.
  rawdec: add framerate private option.
  x11grab: add framerate private option.
  fbdev,v4l2: remove some forgotten uses of AVFormatParameters.time_base.
  bktr: don't error when AVFormatParameters.time_base isn't set.
  cmdutils: add missing const qualifier
  Skip headers not designed to work standalone during 'make checkheaders'.
  Add missing #includes to make headers self-contained.
  musepack: remove unnecessary #include from mpcdata.h
  musepack: remove extraneous mpcdata.h inclusions
  Fix error check in av_file_map()

Conflicts:
	cmdutils.c
