This makes sure the various DSP contexts get properly initialized in
ff_h264_set_parameter_from_sps() whatever the value of
raw_bits_per_sample.

There is in general no reason for the currently active SPS to be the one
referenced by the PPS being parsed.

The way it is currently designed is fundamentally unsafe and cannot be
reasonably fixed without completely rewriting it.

Since we are not doing encoding, there is no point in ever touching the
separate encoding context. Always use the stream codec context.

Fixes writing attachments.

This is the same as is done for SPS.

This allows the callers to have a hint of the probable stream parameters
without actually decoding anything.

Additionally always set the software pixel format, so it's available
even if ff_get_format() is not called later. This will be useful for
exporting stream parameters from init().

Make sure we don't buffer up more than max_delay worth of data
before writing a PES packet, even if pes_payload_size is set to
a larger value.

AviSynth 2.6 (and by extension, AviSynth+) moves these functions
into AVSC_API. This requires both adjusting their normal use,
and for AvxSynth, adjusting the position/use of the USING_AVISYNTH
ifdefs.

Rename the existing tscc2 test.

This will allow to copy the matrix as is and it is just cleaner to keep
the matrix in the same order specified by the mov standard (which is
also explicitly described in the documentation).

In order to preserve compatibility, flip the angle sign in the display API
av_display_rotation_set() and av_display_rotation_get(), and improve the
documentation mentioning the rotation direction.

These are essential allowing QuickTime to keep detecting content
as slow-motion - this allows preserving them on stream copy.
