Track title (atom 'name') is a well defined user data atom for mov files. Existing code (for mp4) only writes title metadata if present.

When building with libopenmpt 0.3, use the libopenmpt file header
probing functions for probing. libopenmpt probing functions are
allocation-free and designed to be as fast as possible.

For libopenmpt 0.2, or when libopenmpt 0.3 file header probing cannot
probe successfully due to too small probe buffer, test the filename
against the file extensions supported by the libopenmpt library that
is actually linked, instead of relying on a hard-coded file extension
list. File extension testing is also allocation-free and designed to
be fast in libopenmpt. Avoiding a hard-coded file extension list is
useful because later libopenmpt versions will likely add support for
more module file formats.

libopenmpt file header probing is tested regularly against the FATE
suite and other diverse file collections by libopenmpt upstream in
order to avoid false positives.

FATE passes with './configure --enable-libopenmpt' as well as with
'./configure --enable-libopenmpt --enable-libmodplug'.

libopenmpt probing adds about 5%..10% cpu time (depending on precise
usage pattern and host CPU and compiler version used for libopenmpt)
compared to all current internal FFmpeg probing functions combined in
tools/probetest for all of its module formats combined (currently 41
modules formats in libopenmpt 0.3.4 and 234 file formats in FFmpeg).

When a decoded stream is being looped, after each post-EOF rewind,
decoders are flushed in seek_to_start(). This only drains 1 frame, and
thus the output has a few frames missing at the tail of each iteration
except the last.

With this patch, process_input is looped till process_input_packet
reaches EOF.

Fixes building with VAAPI but not libdrm, which was broken by
389f4c3e.  Just unconditionally include
the header, since it doesn't depend on libdrm being present.

This can remove units with types in or not in a given set from a stream.
For example, it can be used to remove all non-VCL NAL units from an H.264 or
H.265 stream.

vaGetDisplayDRM() is required for this code to work, libdrm is not.

Use it as the set of codec IDs supported by the trace_headers BSF.

The SEI NAL is unused since 69062d0f,
while the AUD NAL is small and would more sensibly be on the stack.
