Merge remote-tracking branch 'qatar/master'
* qatar/master:
x86: Only use optimizations with cmov if the CPU supports the instruction
x86: Add CPU flag for the i686 cmov instruction
x86: remove unused inline asm macros from dsputil_mmx.h
x86: move some inline asm macros to the only places they are used
lavfi: Add the af_channelmap audio channel mapping filter.
lavfi: add join audio filter.
lavfi: allow audio filters to request a given number of samples.
lavfi: support automatically inserting the fifo filter when needed.
lavfi/audio: eliminate ff_default_filter_samples().
