c0c6b68ddb tools/target_dec_fuzzer: assume that discarded audio packets produced max samples 
We do not know how many samples these produce as its not exported.
Alternatively we could export that but as long as its not we better
assume its more than 0 as otherwise the thresholds would not work

ee33fecb62 avcodec/mpeg12dec: Limit maximum A53 CC size 
This is more than 10 times the size of the largest i found. And also alot more
than our encoder could handle (our encoder is limited to max 31)
Without any limit megabyte+ sized blocks can be reallocated millions of times.
Sadly the SCTE-20 spec does not seem to contain any hard limit directly, so this limit here
is arbitrary

746ab8327c avcodec/asvenc: Avoid reversing output data twice 
The ASUS V2 format is designed for a little-endian bitstream reader, yet
our encoder used an ordinary big-endian bitstream writer to write it;
the bits of every byte were swapped at the end and some data (namely the
numbers not in static tables) had to be bitreversed before writing it at
all, so that it would be reversed twice.

This commit stops doing so; instead, a little-endian bitstream writer is
used. This also necessitated to switch certain static tables, which
required trivial modifications to the decoder (that uses the same
tables).

cdf7619705 avcodec/asvdec: Avoid reversing input data twice 
Up until now the ASV2 decoder used an ordinary big-endian bitreader to
read data actually destined for a little-endian bitreader; this is done
by reversing the whole input packet bitwise, using the big-endian
bigreader and reversing (and shifting) the result again. This commit
stops this and instead uses a little-endian bitreader directly.

d4c46dc328 avcodec/movtextenc: fix writing to bytestream on BE arches 
Fixes fate-binsub-movtextenc on PPC64

Currently tags are written in reverse order on BE arches. This is fixed
by using MKBETAG() and AV_RB32() to be arch agnostics.

Also s->font_count is of type int. On BE arches with 32bit int,
count = AV_RB16(&s->font_count) will read two most significant bytes
instead of the least significant bytes. This is fixed by assigning
s->font_count to count first.

The final change is modifying the type of len. On BE arches
the most significant byte of the int was written instead of the least
significant byte.
