When using streaming input, it may be possible to see frames that appear
before the current_frame.  When these frames are inserted into the
index, the current_frame needs to be updated so it is still pointing
at the same frame.

DDS1 chunks are decoded in 2x2 blocks, odd chunk width or height is not
allowed in that case. Also ensure that the decode buffer is big enough
for all blocks being processed.

It is not necessary to pad to the CTU size.  The CB size of 8x8 should be
sufficient, but due to constraints in the Intel driver (the one usable
implementation of this) it has to be padded to 16x16 like in H.264.

Matching the H.264 encoder.

Also improves the metadata and generally makes the configuration
a bit cleaner.

Included by default with non-IDR intra frames.

Adds a new private option to enable them (off by default).

This is able to modify some header metadata found in the VPS/SPS/VUI,
and can also add/remove AUDs.

This applies a specific fixup to some Bluray streams which contain
redundant PPSs modifying irrelevant parameters of the stream which
confuse other transformations which require correct extradata.

A new single global PPS is created, and all of the redundant PPSs
within the stream are removed.

This is able to modify some header metadata found in the SPS/VUI,
and can also add/remove AUDs and insert user data in SEI NAL units.

Supports all streams that the coded bitstream infrastructure does
(currently H.264 and H.265).
