This target was added to prevent some files being deleted

Current GCC versions know how to generate these instructions
properly and avoiding inline asm gives better code.  The MULH
function for ARMv5 uses the same instruction and is also not
needed any more.

The MLS64 macro remains since negating an input would normally
not be allowed as it would fail for INT_MIN.  In our uses, the
inputs never have this value and thus negating is safe.

Remove AVFilterBufferRefAudioProps.size, and use nb_samples in
avfilter_get_audio_buffer() and avfilter_default_get_audio_buffer() in
place of size.

This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.

This is consistent with the order of parameters in
av_samples_fill_arrays().

The new layout is consistent with that of the av_image_() API, and
simplifies understanding and copy operations, it also preserves
alignment information which was lost with the previous layout.

This breaks API/ABI, but since the function was never referenced in
the code (and it isn't unlikely already used by someone) then this
should not be a problem.

output-example.c (and renamed to muxing-example.c) has been moved to
doc/examples.

The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.

Parts are inspired from the 8-bit H.264 predict code in Libav.
Other parts ported from x264 with relicensing permission from author.

It is only used on the host and may not compile on the target.

The filename is unnecessary and brittle across file renames.

It's simpler and less error-prone.

Fixes some memleaks along the way.
