Do not show the message for the first frame by default, show a
warning if increasing is necessary in the middle of the stream.

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.

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.
