This is a workaround until avcodec_close() stops freeing ch_layout through
av_opt_fre(), or the former is removed.

The IMF demuxer did not implement AVInputFormat::read_seek2(), resulting in
inefficient input seeking.

The rationale is the same as for the wrappers for inflateInit(),
although the case for it is admittedly not so strong because
there are less users of deflateInit().
Also remove an unnecessary inclusion of config.h in
libavformat/protocols.c in order to trigger a request for reconfigure
(which is needed for CONFIG_DEFLATE_WRAPPER to take effect).

This avoids unnecessary churn and build breakage for users, by
making sure the whole version.h is included like it has been so far,
while keeping the benefit of not needing to rebuild most files in
the ffmpeg tree on minor/micro bumps.

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

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.

Since the request_channel_layout is used only by a handful of codecs,
move the option to codec private contexts.
