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 Merged-by: Michael Niedermayer <michaelni@gmx.at>
