To allow adding proper negotiation, in particular, to fftools.
These values will simply be negotiated downstream for YUV formats, and
ignored otherwise.
Motivated by YUVJ removal. This change will allow full negotiation
between color ranges and matrices as needed. By default, all ranges and
matrices are marked as supported.
Because grayscale formats are currently handled very inconsistently (and
in particular, assumed as forced full-range by swscale), we exclude them
from negotiation altogether for the time being, to get this API merged.
After filter negotiation is available, we can relax the
grayscale-is-forced-jpeg restriction again, when it will be more
feasible to do so without breaking a million test cases.
Note that this commit updates one FATE test as a consequence of the
sanity fallback for non-YUV formats. In particular, the test case now
writes rgb24(pc, gbr/unspecified/unspecified) to the matroska file,
instead of rgb24(unspecified/unspecified/unspecified) as before.
Some encoders (e.g., libx264) dump encoder configuration as user
data unregistered SEI message. This option try to print it as
ascii character when possible.

This can be used to run tests multple times, with e.g. differing
QEMU settings, by adding something like this to the FATE configuration
file:
target_exec="qemu-aarch64-static"
fate_targets="fate-checkasm fate-cpu"
fate_environments="sve128 sve256 sve512"
sve128_env="QEMU_CPU=max,sve128=on"
sve256_env="QEMU_CPU=max,sve256=on"
sve512_env="QEMU_CPU=max,sve512=on"
It's also possible to customize the target_exec command further
by injecting a sufficiently quoted variable into it, which then can
be updated for each run, e.g. target_exec="\$(CUR_EXEC_CMD)".
For each of the environment names in fate_environments, the tests
that are run get the name suffixed on the fate tests in the
test log and fate report, e.g. "fate-checkasm-h264dsp_sve128".

This can be useful if doing testing of uncommon CPU extensions by
running tests with QEMU (by configuring with e.g.
"target_exec=qemu-aarch64"), by only running the checkasm tests,
to get a reasonable test coverage without excessive test runtime.
For such a config, setting fate_targets="fate-checkasm fate-cpu"
can be a good tradeoff.

The {br}/{abr} directives are not limited to post-encoding, they can
also be used pre-muxing. The already-present {packet} tag describes this
more accurately, so just drop the assertions.
x11grab can capture windows by their ID, but gdigrab can only capture
windows by their names, internally calling FindWindowW to lookup its
handle.
This patch simply allows the user to specify a window handle directly.

3d29724c00 removed the doc entry for the option pool while adding
a parser function for it at the same time!
The option remains available and undeprecated.
