amerge/astreamsync/pan: fix license boilerplate.
The boilerplate states that the files are under LGPL,
but refer the user to the GPL at one place.
These files were (re)implemented specifically for FFmpeg.
Some calculations were changed in b6a3849 to use mmsize, which was not correct
for the AVX version, which uses INIT_YMM and therefore has mmsize == 32.

dct-test: always link with aandcttab.o
This allows building dct-test even if aandcttab.o is not pulled in
by any enabled codec. The DCT with which these tables are used does
not use them directly, so building it without the tables is possible.

vp8: pack struct VP8ThreadData more efficiently
Reordering the members in this struct reduces the holes required
to maintain alignment. With this order, the only remaining, and
unavoidable, hole is 3 bytes following left_nnz.

x86: remove libmpeg2 mmx(ext) idct functions
These functions are not faster than other mmx implementations on
any hardware I have been able to test on, and they are horribly
inaccurate. There is thus no reason to ever use them.
lavfi/video: remove duplicated function ff_null_start_frame_keep_ref()
Semantic for the function ff_null_start_frame() was changed in 07bad27810cd, and it has now the same behavior of
ff_null_start_frame_keep_ref(), thus it makes no sense to keep both of
them.

ffmpeg: honor -ss and -t parameters with muxed subtitles.
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.

vf_tile: fix output buffer ownership.
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 standard syntax requires two destination registers for

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
