Use AV_PKT_FLAG_CORRUPT flag to mark packets that might be incomplete
or have errors. Formats that have a mean to validate their packets
should use this flag to deliver such information instead of silently
dropping the packets.

It doesn't work and is therefore useless.

It's unused an serves no purpose.

When converting RGB format to RGB format with the same bits per sample,
unscaled path performs conversion on the whole buffer at once. For
non-multiple-of-16 BGR24 to RGB24 conversion it means that padding at the
end of line will be converted too. Since it may be of arbitrary length
(e.g. 8 bytes), operating on the whole buffer produces obviously wrong
results.

The link target was missing $(EXAMPLES)

This prevents out of bounds reads when extradata is being decoded.

A loop control variable was shadowed inside the loop and never updated.

mpegts_read_header is used by both mpegts and mpegtsraw, so this
erro check is no longer valid.

It's more readable and less prone to breakage.

This fixes build with clang.

Inspection of compiled code shows gcc handles these fine on its own.
Benchmarking also shows no measurable speed difference.

Removing the remaining cases in get_cabac_bypass_sign_x86() does
cause more substantial changes to the compiled code with uncertain
impact.

Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical
for most codecs, move Bink IDCT into separate context. Get rid of an additional
permutation table while at it since SIMD support for Bink IDCT is unlikely to
be implemented in foreseeable future.
Quantisation tables also have to change type to signed for proper
dequantisation of DCT coefficients.
