ffmpeg: Compensate non monotonicity errors in the audio TSs.
Audio timestamps are passed through by default and when the input
doesnt contain clean timestamps this can lead to non monotonicity
errors. (rounding to a course timebase can cause this too)
Print a warning when the errors in the timestamps are large
Fixes Ticket1167 (regression since timestamps are passed through)
This is a generic workaround that is intended to handle
slightly incorrect input files. It is very possible that some
demuxers contain bugs that lead to wrong timestamps, these demuxers
should of course still be fixed even if this change happens to
hide the issue.

x86inc improvements for 64-bit
Fixes potential out-of-bounds writes.
This is mostly possible when muxing ALS files where from
an extradata size of about 1050 put_bits would write data
outside the buffer.
For the FATE test sample used, this only avoids a warning
message.
However for other samples like al05_44.mp4 the converted
file can be played only after this fix.
This will only work for DSEs that are first in a packet, but
that is enough to fix handling of the reference files in
fate-suite/aac (though most of them still have other issues).

wmalosslessdec: Reset residues to 0 if they were not decoded from bitstream.
If channel residues are have not been decoded from bitstream, they should be
initialized to 0 instead of using values from previous subframe.
This causes bursts of noise in silent parts of some files.

Otherwise for muxers like e.g. latmenc that never call
avio_flush (and do not have a write_trailer function)
a part of the data will always be missing.
Also update references for the voc muxer, which was also
buggy before and did not write out all data.

interplayvideo: fix av_dlog parameter type mismatch
Drop some pointless #ifdefs.
"Fix" in so far as at least it will no longer overread and possibly
crash and makes somewhat sense, but no idea whether there is anything
that can play the resulting files (FFmpeg can't).
Currently they end up twice in the binary, since both
encoder and decoder include the header and thus each gets
their own copy.
This is clearly nonsense for the const tables, but shouldn't
be necessary for the RLTable either.

avplay: Don't free video filters string until the end of decoding.
av_freep()ing inside configure_video_filters() leaves a dangling
reference in the calling code, and the filter string is needed again when
reconfiguring video filters for a size change.
Share the formerly internal write_packet with the hinter and move the
fragment flush logic to the user facing one since it is not concerned
about movtrack-only streams.

rv40dsp: implement prescaled versions for biweight.
Quite often, the original weights are multiple of 512. By prescaling them
by 1/512 when they are computed (once per frame), no intermediate shifting
is needed, and no prescaling on each call either.
The x86 code already used that trick.

avconv: use default channel layouts when they are unknown
If either input or output layout is known and the channel counts match,
use the known layout for both. Otherwise choose the default layout based on
av_get_default_channel_layout().
Changed some FATE references due to some WAVE files now having a non-zero
channel mask.

mem: Consistently return NULL for av_malloc(0)
Plain POSIX malloc(0) is allowed to return either NULL or a
non-NULL pointer. The calling code should be ready to handle
a NULL return as a correct return (instead of a failure) if the size
to allocate was 0 - this makes sure the condition is handled
in a consistent way across platforms.
This also avoids calling posix_memalign(&ptr, 32, 0) on OS X,
which returns an invalid pointer (a non-NULL pointer that causes
crashes when passed to av_free).
Abort in debug mode, to help track down issues related to
incorrect handling of this case.

avconv: allow '-async -1' to disable timestamp sync for audio encoding
This will allow a workaround for cases where input timestamps are invalid or
when decoder delay of 1 packet or more confuses avconv into using the wrong
timestamps as a sync reference.
