88d80cb975 changed the type of
PutBitContext.BitBuf to uint64_t; it used to be an uint32_t.
While said structure is not public, it is nevertheless used by
certain avpriv functions and therefore crosses library boundaries:
avpriv_align_put_bits and avpriv_copy_bits were used in other libraries
in release 4.3 (and at the time of 88d80cb9) and so this commit broke
ABI.
This commit mitigates the trouble caused by this by using an uint32_t
again, but only for the 4.4 release branch and not the master branch,
as doing so for master, would break the ABI of master again, although
it is very unlikely that anyone would be helped by this (there don't
seem to be any users that combine libavcodec built from master and
libavformat from an old release: otherwise we would have received bug
reports about said ABI break).

This is how it is supposed to happen, yet when using frame threading,
the codec's init function has been called before preinit. This can lead
to crashes when e.g. using unsupported lowres values for decoders
together with frame threading.

(cherry picked from commit 746796ceb4)
When flushing, the parser receives a dummy buffer with padding
that lives on the stack of av_parser_parse2(). Certain parsers
(e.g. Dolby E) only analyze the input, but don't repack it. When
flushing, such parsers return a pointer to the stack buffer and
a size of 0. And this is also what av_parser_parse2() returns.
Fix this by always resetting poutbuf in case poutbuf_size is zero.

Commit 6973df1122 added support
for music tracks by outputting its two containing tracks
together in one packet. But the actual data is not contiguous
in the file and therefore one can't simply use av_get_packet()
(which has been used before) for it. Therefore the packet was
now allocated via av_new_packet() and read via avio_read();
and this is also for non-music files.
This causes problems because one can now longer rely on things
done automatically by av_get_packet(): It automatically freed
the packet in case of errors; this lead to memleaks in several
FATE-tests covering this demuxer. Furthermore, in case the data
read is less than the data desired, the returned packet was not
zero-allocated (the packet's padding was uninitialized);
for music files the actual data could even be uninitialized.
The former problems are fixed by using av_get_packet() for
non-music files; the latter problem is handled by erroring out
unless both tracks could be fully read.

(cherry picked from commit e668c55649)
When extended atom size support was added to probing in
fec4a2d232d7ebf6d1084fb568d4d84844f25abc, the buffer
size check was backwards, but probing continued to work
because there was no minimum size check yet, so despite
size being 1 on these atoms, and failing to read the 64-bit
size, the tag was still correctly read.
When 0b78016b2d introduced a
minimum size check, this exposed the bug, and broke probing
any files with extended atom sizes, such as entirely valid
large files that start whith mdat atoms.
