aac: Split function to parse ADTS header data into public and private part

ac3_parser: add a public function for parsing the data required by the demuxer
avpriv_ac3_parse_header() is left in place but without the
GetBitContext parameter, as the mov muxer requires a lot more fields
than just bitstream_id and frame_size from the AC3HeaderInfo struct.

This applies a specific fixup to some Blu-ray 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.
(cherry picked from commit e6874bc3af)
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.

This adds hardware decoding for H.264 / HEVC / VP8 / VP9 using the MPP
Rockchip API. It returns frames holding an AVDRMFrameDescriptor struct
in buf[0] that allows drm / dmabuf usage. Tested on RK3288 (TinkerBoard)
and RK3328.

This commit implements a psychoacoustic system for the native Opus
encoder. Its unlike any other psychoacoustic system known since its
capable of using a lookahead to make better choices on how to treat the
current frame and how many bits to allocate for it (and future frames).
Also, whilst the main bulk of the analysis function has to run in a
single thread, the per-frame anaylsis functions does not modify the main
psychoacoustic context, so in the future it will be fairly trivial to
run those as slice threads.

This patchset enhances Alexis Ballier's original patch and validates
it using Qualcomm's Venus hardware (driver recently landed upstream
[1]).
This has been tested on Qualcomm's DragonBoard 410c and 820c
Configure/make scripts have been validated on Ubuntu 10.04 and
16.04.
Tested decoders:
- h264
- h263
- mpeg4
- vp8
- vp9
- hevc
Tested encoders:
- h264
- h263
- mpeg4
Tested transcoding (concurrent encoding/decoding)
Some of the changes introduced:
- v4l2: code cleanup and abstractions added
- v4l2: follow the new encode/decode api.
- v4l2: fix display size for NV12 output pool.
- v4l2: handle EOS (EPIPE and draining)
- v4l2: vp8 and mpeg4 decoding and encoding.
- v4l2: hevc and vp9 support.
- v4l2: generate EOF on dequeue errors.
- v4l2: h264_mp4toannexb filtering.
- v4l2: fixed make install and fate issues.
- v4l2: codecs enabled/disabled depending on pixfmt defined
- v4l2: pass timebase/framerate to the context
- v4l2: runtime decoder reconfiguration.
- v4l2: add more frame information
- v4l2: free hardware resources on last reference being released
- v4l2: encoding: disable b-frames for upstreaming (patch required)

Intended for use with hardware frames for which rawvideo is not
sufficient. Requires the trusted packet flag to be set - decoding
fails if not to avoid security issues (the wrapped AVFrame can
contain pointers to arbitrary data).

It is redundant with costable. The first half of sintable is
identical with the second half of costable. The second half
of sintable is negative value of the first half of sintable.
The computation is changed to handle sign of sin values, in
C code and ARM assembly code.

Takes a raw input stream containing frames with correct timestamps but
possibly out of order and inserts additional show-existing-frame
packets to correct the ordering.

Also converted from bitstream to get_bits.
The library has stopped being developed and Debian has removed it
from its repositories citing security issues.
The native Dirac decoder supports everything the library has and basic
encoding support is still provided via the native vc2 (Dirac Pro, intra
only version of Dirac) encoder. Hence, there's no reason to still support
linking to the library and potentially leading users into security issues.
Enables rendering of SVG images. This is possible since SVG images
still contain and specify the dimensions in pixels to which they've
been drawn to and thus enable browsers to display them without any
external data. Users can still override and generate images with
arbitrary resolutions.

This makes the currently semi-public avpriv_aac_parse_header() function
private to libavcodec and adds a proper public API function to return
the parts of the ADTS header required in libavformat.
