4b8bb69f55 avcodec/tiff: Restrict tag order based on specification
"The entries in an IFD must be sorted in ascending order by Tag. Note that this is
 not the order in which the fields are described in this document."

This way various dimensions, sample and bit sizes cannot be changed at
arbitrary times which reduces the potential for bugs.
The tag reading code also on various places assumes that numerically previous
tags have already been parsed, so this needs to be enforced one way or another.

If this commit causes problems with real world files which are not easy to fix
then some other form of checks are needed to ensure the various dependencies
in the tag reading are not violated.

1498f31b5b avcodec/alac: Check decorr_shift to avoid invalid shift
Later the decorrelate_stereo call is guarded by channels == 2
and non-zero decorr_left_weight. Make sure decorr_shift is in
the expected shift range for that case.

Fixes: shift exponent 128 is too large for 32-bit type 'int'

ca55240b8c avformat/mpegts: make sure mpegts_read_header always stops at the first pmt
mpegts_read_header stops parsing the file at the first PMT. However the check
that ensured this was wrong because streams can also be added before the first
PMT is received (e.g. EIT).

So let's make sure we are in the header reading phase by checking if ts->pkt is
unset instead of checking if the number of streams found so far is 0.

avformat/argo_asf: fix handling of v1.1 files
Version 1.1 (FX Fighter) files all have a sample rate of 44100
in the header, but only play back correctly at 22050.

Force the sample rate to 22050 when reading, and restrict it
when muxing.
