da9cc22d5b allowed the MOV muxer to relay a custom stream handler name,
whether populated from the input stream or user-set. However, the entry
key didn't match the key set by the MOV demuxer, so it wasn't
effective. Fixed.
Due to the change, four FATE refs have to be updated. Verified that the
target payload of the tests hasn't changed in terms of CRC.
CLI options -maxrate, -bufsize and -rc_init_occupancy can now be picked
up by the x265 wrapper. Min. rc init has to be 1001 to avoid x265
setting it to vbv-bufsize.
In 9152c1e495, the mpegts parser was taught how to parse
PMT sections which contained multiple tables. That commit
fixed parsing of PMT packets from some cable providers,
which included a special SCTE table (0xc0) before the
standard program map table (0x2).
Sometimes, however, the combined 0xc0 and 0x2 tables are
larger than a single TS packet (188 bytes). The mpegts parser
already attempts to parse sections which span multiple packets,
but still assumed that the split section only contained one
table.
This patch fixes parsing of such a sample[1].

Stream #0:6[0xf03]: Unknown: none ([192][0][0][0] / 0x00C0)
With the patch, the PMT is parsed correctly so the streams are
created in the correct order, are associated with "Program 1",
and their codecs are set correctly.

@xyz reported a regression on his Sony Xperia Z3 Tablet Compact where
playback would intermittently fail to start, essentially deadlocking in
the decoder. Bisecting narrowed down the issue to this commit, which was
meant as an optimization but is not necessary.

When using hardware accelerated decoding for multi-slice field interlaced pictures,
only the first slice was decoded. This patch adds the neccesary looping over the
remaining slices that may exist in field interlaced pictures. Additionally, we align
the calculation of mby_start for the second field with the method given in VC-1 spec.

Overlap filtering I and BI frames for Simple and Main profile is only
dependent on PQUANT. Restrict testing for CONDOVER and OVERFLAGS to
advanced profile. Change from mb_width to end_mb_x in ff_vc1_i_loop_filter
to avoid breaking the Microsoft Screen 2 decoder.

The v_overlap_filter needs to run on the colocated block of the previous
macroblock. For the luma plane, the colocated block is located two blocks
on the left instead of one. In addition, the overlap filter needs to run
on the non-edge blocks of the first macroblock row and column.
Fixes ticket #7171.
