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

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.

This also disabled the case of mixed x/ymin with tiles, the code
handles these cases inconsistent for the 2 coordinate axis and is
unlikely working correctly.

"[av_frame_copy_props()] potentially contains memory allocation,
so the return value needs to be checked."

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.
