vf_colorspace: Add support for full range yuv
Whenever a full range video is input, since the YUVJ* formats are not
listed as supported for this filter, a range reduction takes place
through the auto-inserted format filter, forcing the conversion to
operate on a limited range,
However the filter handles full range videos perfectly fine, so adding
support to YUVJ* formats will allow skipping a conversion step, while
providing completely identical results.

af_hdcd: for easier maintenance alongside libhdcd
Mostly just re-arranges some code to make it easier to update this
filter and libhdcd together. filter_frame() is much simpler as a
result.
* use the HDCD detection data structure and functions from libhdcd,
moved detection code out of filter_frame()
* moved analyze_mode preparation out of filter_frame() into
hdcd_analyze_prepare(), from libhdcd
* moved some macro definitions to the top so they are all together

tests/audiomatch: Fix compile warning
Making sure bestpos is initialized to zero to prevent gcc from kvetching.
It's harmless (although it's not obvious that it's harmless)
from code inspection:
tests/audiomatch.c: In function ‘main’:
tests/audiomatch.c:40: warning: ‘bestpos’ may be used uninitialized in this function
Thanks to Moritz Barsnick for first bringing this to the attention.

handles these cases inconsistent for the 2 coordinate axis and is
unlikely working correctly.

memalign() is not guranteed to be compatible with free() or realloc()
and for platforms in this category we have --enable-memalign-hack
(which should be enabled automatically if such system is detected)
Trying to somehow half support systems that can free() memalign memory
but not reallocate it seems not worth the amount of work needed to
keep 2 then incompatible allocation systems and ensure their
seperation. That is unless this would affect a major platform
on which we want to avoid the memalign hack code
The warnings also cause wasted time and effort as people try
to maintain a separation that does not exist currently.

libavformat/mov: Accept known codepoints in 'colr'
This change relaxes the whitelist on reading color metadata in MOV/BMFF
containers. The whitelist on writing values is still in place.
As a consequence it also fixes an apparent bug in reading 'nclc' values.
The 'nclc' spec [1] is in harmony with ISO 23001-8 for the values it
lists, but the code getting removed was remapping 5->6 and 6->7 for
primaries, which is incorrect, and was remapping 6->5 for color matrix
("colorspace" in the code), which is equivalent but an unnecessary
inconsistency. This logic error doesn't appear in movenc.
Removing the whitelist allows proper conversion when the source codec
relies on the container for proper signaling of newer codepoints, such
as DNxHR and VP9. If converting to a codec or container that has updated
its spec to include the new codepoints, the metadata will be preserved.
If going back to MOV/BMFF, the output whitelist will still kick in, so
this won't result in out-of-spec files being created.
