Split long comments, move long comments at the end of lines to
separate lines above, fix vertical alignment, fix up comment style
(unify trailing dots - comments had a mix of 2, 3 or 4 dots, where
it would be just as good without them at all).

Wrong bit depth can lead to invalid rowsize values, which crashes the
decoder further down.

Commit adebad07 "arm: intreadwrite: fix inline asm constraints for gcc
4.6 and later" caused some older gcc versions to miscompile code.
This reverts to the old version of the code for these compilers.

The decoder assumes in various places that the image size
is a multiple of the block size, and there is no obvious
way to support odd sizes.  Bailing out early if the header
specifies a bad size avoids various errors later on.

Fixes CVE-2012-0947.

This avoids returning duplicate timestamps for multiple packets when the
demuxer does not provide all timestamps and packet duration is not known.

This modifies pts in situations other than what was intended, leading to
invalid timestamps.

Progressive data is allocated later in decode_sof(), not allocating

This prevents sample_rate/data_length from going negative, which
caused various crashes and undefined behaviour further down.

It was to signal that allocations are 16-byte aligned, but AVX requires
32-byte alignment, thus the check is no longer useful (and causes
crashes).

This properly synchronizes frame size changes between threads if
subsequent threads abort decoding before frame size is initialized, i.e.
it prevents the thread after that from ping-ponging back to the original
value.
