This patch fixes two things:

 - in case of subtitles, check_recording_time() is comparing the current
   PTS to the recording time (-t option, set to INT_MAX by default), so
   the -ss option needs to be taken into account. It is not required in
   do_{audio,video}_out() because this adjustment is set while polling
   the filtergraph (see poll_filters()).

 - It also adjusts the PTS sent to the encoder (and later transmitted to
   the muxer) so the TS in the output make sense and are not kept
   verbatim.

Note: this only works for muxers honoring the PTS, such as
lavf/matroskaenc. But for other such as the ASS muxer which just does a
verbatim copy, or the SubRip muxer which doesn't write the TS in some
cases, it will not work yet.

The previous validity check seems to work only for some
(presumably older) files, in current versions the first bytes
now contain the data size.

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.

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.

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.
