Should fix compilation on clang.

There is no need to start_frame immediately on the output link
since the rest is only done with the last frame of the tile.
link->out_buf is now automatically dereferenced; since we give
it away it must be cleared.

Fix an assert failure; found by Clément Bœsch.

Fix an assert failure with packets of invalid size.

Fixes ticket #1580

Pallete is written to frame->data[1] only if it changes.
This fixes PAL8->PAL8 transcoding.

The return value was the number of bytes left,
it is supposed to be the number of bytes used.

Commit 2bf09826 introduced an overflow check in loco_decode_plane,
but the error code is never taken into account, leading to
completely idiotic return values.

i is the decoded size of a recoded packet, which is larger
than the original packet. Assume that if decoding succeeded,
all the packet was used.

samples_size and samples_idx are supposed to be multiple of
channels at all time. If they are, the division is exact;
if they are not, something is very wrong in the code.

esc->table was inited based on codec->id: re-testing codec->id
is code duplication and can lead to inconsistencies.

MM_PREAMBLE_SIZE is subtracted from buf_size almost immediately.
The original size is still in avpkt->size.

Add "data" and "extradata" attributes to the schema.
Add "tag" element in "streams".
Print extradata before tags to avoid closing the element.

Fix trac ticket #1588.

This fixes compilation with YASM disabled.

The yadif mmx optimizations contain the pmaxsw and pmaxub mmxext
instructions, causing sigills on CPUs that do not support mmxext.

This ensures that the output buffers will have the channel layout set,
which is required by filters.

Also consistent with ffmpeg.c behavior.

This is required otherwise it is not always possible to guess the number
of channels from the layout, for example if the channel layout is
unknown.

There is no need to duplicate the input reference, since a filter should
not pass along a reference which is later modified. If this happens the
filter passing the reference should be fixed.

Also improve consistency with start_frame() of settb, allowing a pending
factorization.

The documentation was erroneously removed in 7cf9aadd.

This completes the conversion of h264dsp to yasm; note that h264 also
uses some dsputil functions, most notably qpel. Performance-wise, the
yasm-version is ~10 cycles faster (182->172) on x86-64, and ~8 cycles
faster (201->193) on x86-32.
