vorbis.h currently contains stuff only used by the native
Vorbis codecs and some Vorbis tables, which are also used by
Opus and libvorbis. Therefore split the data out into a header
of its own.

Don't increment back_frame if it does not correspond
to a real buffer. To do this, handle copying from
the back frame separately from the "use coded value"
codepath; also use memcpy for the former, as the
chunks here are typically worth it.

This check is intended to be avoid buffer overflows,
yet there are four problems with it:
1. It has an in-built off-by-one error: len == out_end - out
is perfectly fine and nothing to worry about.
This off-by-one error led to the pixel in the lower-right corner
not being set properly for the back frame of the sample from
the rl2 FATE-test. This pixel is copied to every frame which
is the reason for the update to the reference file of said test.
With this patch, the output of the decoder matches the output
as captured from the reference decoder* (apart from the fact
that said reference somehow lacks the top part of the frame
(copied over from the background frame)).
2. Given that the stride of the buffer may be different
from the width of the video (despite one pixel taking one byte),
there is a second check lateron making the first check redundant
(if one returns immediately; a simple break at the second check
is not sufficient, because it only exits the inner loop).
3. The check is based around the assumption of the stride being
positive (it has this in common with the other check which
will be fixed in a future commit).
4. Even after fixing the off-by-one error, the check in
question is still triggered by all the non-background frames
in the FATE sample as well as by A1100100.RL2. In all these
cases, they use len == 255 and val == 128. For videos with
background frame this just means "copy from the background
frame", which would be done anyway lateron.* Yet for videos
without it copying it is necessary to avoid leaving
uninitialized parts in the video.
*: Available in https://samples.mplayerhq.hu/game-formats/voyeur-rl2/
**: Due to this, the code that copies the rest from the
back frame is no longer executed for any of the samples
available on the sample server. Given that these are only
the files from the demo version of this game, I don't know
whether this code is executed for any file in existence or not.

It is only used by three of the thirty files that (potentially
indirectly) include mpeg4audio.h. Twenty of these files won't
have a put_bits.h inclusion any more after this patch.

This allows av_mediacodec_release_buffer to be called safely after
the decoder is closed, this was already the case with delay_flush=1.
Note that this causes holding onto frames to keep the decoding context
alive which is generally considered to be the intended behavior.

ff_check_pixfmt_descriptors() was added in commit
20e99a9c10cdbe9ad659dce5bdec569d744f8219. At this time,
the values of enum AVPixelFormat were not contiguous;
instead there was a jump from 111 to 291 (or from 115
to 295 depending upon AV_PIX_FMT_ABI_GIT_MASTER).
ff_check_pixfmt_descriptors() accounts for this
by skipping empty descriptors. Yet this issue no longer
exists: There are no holes.
The check for said holes makes GCC believe that the name
can be NULL; because it is used as argument corresponding to
%s in a log statement, it therefore emits a warning
(since d75c4693fef51e8f0a1b88798530f4c5147ea906). Therefore
this commit simply removes these checks.
Also move the checks for name before the log statement.

This is currently 64-bit only because the stack spilling code would not
assemble on RV32I (and it would corrupt s0 and s1 on RV128I, in theory).
This could be added later in the unlikely that someone wants it.

Furthermore, the current code would not work on mips
in case ff_lsp2polyf() were used outside of lsp.c,
because it is not compiled on mips since commit
3827a86eacd04d9d7b356f769be553f7b8cca361 at all;
instead it is overridden with a static av_always_inline
function which only works for the callers in lsp.c.

AVCodec.channel_layouts is deprecated and Clang (unlike GCC)
warns when setting this field in a codec definition.
Fortunately, Clang (unlike GCC) allows to use
FF_DISABLE_DEPRECATION_WARNINGS inside a definition (of an FFCodec),
so that one can create simple macros to set AVCodec.channel_layouts
that also suppress deprecation warnings for Clang.
(Notice that some of the codec definitions were already
inside FF_DISABLE/ENABLE_DEPRECATION_WARNINGS (that were not
guarded by FF_API_OLD_CHANNEL_LAYOUT); these have been removed.
Also notice that setting AVCodec.channel_layouts was not guarded
by FF_API_OLD_CHANNEL_LAYOUT either, so testing disabling it
it without removing all the codeblocks would not have worked.)

Pointers to void can be converted to any pointer to incomplete or
object type and back; but they are nevertheless not completely generic
pointers: There is no provision in the C standard that guarantees their
convertibility with function pointers. C90 lacks a generic function
pointer, C99 made every function pointer a generic function pointer and
still disallows the convertibility with void *. Both GCC as well as
Clang warn about this when using -pedantic.
Therefore use unions to avoid these conversions.
