wm4 66dd21d50b avcodec/utils: split side-data in new decode API too
The deprecated avcodec_decode_video2() and avcodec_decode_audio4()
functions called av_packet_split_side_data() on the input packets. This
is required for packets produced by libavformat with the
AVFMT_FLAG_KEEP_SIDE_DATA flag unset (which is unfortunately the
default).

The new API didn't do this yet, although it didn't matter as no decoder
supports the new API yet. The emulation layer for the old API calls the
old API functions, which took care of the splitting. Add this code to
the new API codec entrypoints too, because we shouldn't send essentially
corrupted data to decoders.

wm4 7fc329e2dd lavc: introduce a new decoding/encoding API with decoupled input/output
Until now, the decoding API was restricted to outputting 0 or 1 frames
per input packet. It also enforces a somewhat rigid dataflow in general.

This new API seeks to relax these restrictions by decoupling input and
output. Instead of doing a single call on each decode step, which may
consume the packet and may produce output, the new API requires the user
to send input first, and then ask for output.

For now, there are no codecs supporting this API. The API can work with
codecs using the old API, and most code added here is to make them
interoperate. The reverse is not possible, although for audio it might.

From Libav commit 05f66706d1.

Michael Niedermayer 21acc4db5f avcodec: Add bits_per_raw_sample to AVCodecParameters
The bits_per_raw_sample represents the number of bits of precision per sample.

The field is added at the logical place, not at the end as the code was just
recently added

This fixes the regression about losing the audio sample precision information

The change in the fate test checksum un-does the change from the merge
