The YUV channels of VP6 are encoded in a highly linear fashion which does
not have any slice-like concept to thread. The alpha channel of VP6A is
fairly independent of the YUV and comprises 40% of the work. This patch
uses the THREAD_SLICE capability to split the YUV and A decodes into
separate threads.
Two bugs are fixed by splitting YUV and alpha state:
- qscale_table from VP6A decode was for alpha channel instead of YUV
- alpha channel filtering settings were overwritten by YUV header parse

This is consistent with stdio and is what we want to do in all cases.
Fixes a bug in the voc muxer which didn't flush in write_trailer()
previously. This is the cause of the change in the test results.
A flashsv2 block may have a "diff block" to indicate which scan lines of
the block are actually encoded. However, this diff block need not be
used when the entire block is coded.

In vp6 Advanced Profile, deblock filtering is conditionally enabled in
each frame header. In Simple Profile it should always be off. vp6 was
inheriting the wrong default from ff_vp56_init.

Fix a failure when running do_lavfi_pixfmts() for the
lavfi-tinterlace_merge and lavfi-tinterlace_pad tests concurrently.
Since they were using the same names for the temporary files, the first
ending test was removing them, and the second test was failing at
removing unexisting files.
Make do_lavfi_pixfmts() support an user-specified name for the test.
This allows to specify two pixfmts tests for the same filter, e.g. to
test a filter with different parameters. Useful for the pending
tinterlace tests.
Previously, the value given to put_bits was 10 bits long for positive
predictors, even though 9 bits were to be written. The extra bit could
in some cases overwrite existing bits in the bitstream writer cache.
This fixes a failed assert in put_bits.h, when running a version
built with -DDEBUG.
The fate test result gets slightly improved, thanks to getting rid
of the overwritten bits in the bitstream writer cache.

Rewrite 10 bit dpx decoder to decode into GBRP10 color space
instead of converting to RGB48.
Add 12 bit decoder to decode into GBRP12 color space.

The failures on various architectures and compilers on the RGB(A)
tests seem to have been because of one-off YCbCr->RGB conversion
results. This should make the conversion results match on most if
not all code paths.

Unsurprisingly, if a timing-less subrip decoder is desireable, an
encoder is as well. With this in place, we can move on to remove
the use of the old encoder/decoder with embedded timing and move
all timing handling the (de)muxer where they belong.

Fixes Ticket1627
The fate change is due to ffmpeg no longer pushing audio timestamps
aggressively up (which is what caused the AV sync issues in the ticket)
but leaving them as they are.

The previous code dependent on the input buffer matching the
buffer that has been provided by yadifs get_buffer.
The API does in now way gurantee this though its often true.
This fixes some out of array reads.
The regression test checksums change due to "out of picture" values

This change introduces a basic encoder for 3GPP Timed Text subtitles,
also known as TX3G, Quicktime subtitles, or "movtext" in the existing
code.
This initial change doesn't attempt to write styling information,
and just writes the plain text of the subtitles. I intend to add
support for styles eventually, but it's challenging due to a lack
of existing players that support them.
Note that an additional change is required to the mov/mp4 muxer to
write empty subtitle packets to indicate subtitle duration.
