While a 25 fps stream can in general store frame durations in 1/25
units, this is not true for the timestamps. For example a 25fps
and a 25000/1001 fps stream when they are stored together might have
a matching 0 timestamp point but when for example a chapter from
this is cut the new start is no longer aligned. The issue gets
MUCH worse when the streams are lower fps, like 1 or 2 fps.
This commit thus makes the muxer choose a multiple of the
framerate as timebase that is at least about 20 micro seconds precise

With this, when we use a finer timebase than neccessary to store
durations the demuxer still knows what the original timebase was.

This generalizes the previous work on disposition printing.
Disposition flags are shown in a dedicated section, which should improve
output intellegibility, extensibility and filtering operations.
This breaks output syntax with the recently introduced disposition
printing.
Be compatible with texi2html 5.0 which doesn't search relative
file names in search paths anymore.

Also factorize the common options for the different mov-based tests.
Since the header is now on top in the last generated file, the data
offset in the seek test needed some updates as well.
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

A flashsv2 block may have a "diff block" to indicate which scan lines of

used when the entire block is coded.

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.
