Only index tables repeating previous index tables should use the same
InstaceUID. Use the index start position when generating the InstanceUID to fix
this.

Output buffer alignment might be different to ZIMG_ALIGNMENT or it may not be
aligned at all if a downstream filter (e.g. vf_pad) intentionally misaligns it.
Or maybe we should unconditionally always allocate output with
av_frame_get_buffer() instead of ff_get_video_buffer()?

Make sure it is between [1, MAX_THERADS] and also take into account the outlink
size in order not to request zero height output from zscale.

This avoids unnecessary rebuilds of most source files if only the
list of enabled components has changed, but not the other properties
of the build, set in config.h.

Also bump the minor versions of all libraries, to signify the
API change of splitting the version.h headers and adding the
new version_major.h header.
Signed-off-by: Martin Storsjö <martin@martin.st>
This avoids including version.h in all source files, avoiding
unnecessary rebuilds when the version number is bumped. Only
version_major.h is included by the main header, which defines
availability of e.g. FF_API_* macros, and which is bumped much
less often.
This isn't done for libavutil/version.h, because that header needs
to be included essentially everywhere due to LIBAVUTIL_VERSION_INT
being used wherever an AVClass is constructed.

bp->len cannot be used to detect if try_describe_ambisonic was successful
because the bprint buffer might contain other data as well.
Also describing an invalid ambisonic layout should not return 0 but
AVERROR(EINVAL) instead, so change try_describe_ambisonic to actually return
error on invalid ambisonics. This also allows us to fix the first issue.

This reduces code duplication an allows printing AMBI%d channel names for
custom layouts for non-standard or partial ambisonic layouts.

Later we use av_channel_layout_copy, but that uninits the struct
unintentionally freeing the possibly allocated u.map pointer.
