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 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)

The filter supports two inputs and (implicitly) scaling the second input
during composition, unlike the software overlay.
The code has been separated into common interface and qsv overlay
implementation. The common part mainly creates the qsv session and
manages the surface which is nearly the same for all qsv filters.
So the qsvvpp.c/qsvvpp.h API can be used by other QSV vpp filters
to reduce code redundancy.
Usage:
-hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv
-i in.h264 -filter_complex
"overlay_qsv=eof_action=repeat:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M
-c:v h264_qsv -y out.h264
Two inputs should have different sizes otherwise one will be completely
covered or you need to scale the second input as follows:
-hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv
-i in.h264 -filter_complex
"overlay_qsv=w=720:h=576:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M -c:v
h264_qsv -y out.h264

This also adds support to avconv (which is trivial due to the new
hwaccel API being generic enough).
The new decoder setup code in dxva2.c is significantly based on work by
Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites.
Merges Libav commit f9e7a2f95a.
Also adds untested VP9 support.
The check for DXVA2 COBJs is removed. Just update your MinGW to
something newer than a 5 year old release.

NASM is more actively maintained and permits generating dependency information
as a sideeffect of assembling, thus cutting build times in half.

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 decoder can decode all existing SpeedHQ formats (SHQ0–5, 7, and 9),
including correct decoding of the alpha channel.
1080p is decoded in 142 fps on one core of my i7-4600U (2.1 GHz Haswell),
about evenly split between bitstream reader and IDCT. There is currently
no attempt at slice or frame threading, even though the format trivially
supports both.
NewTek very helpfully provided a full set of SHQ samples, as well as
source code for an SHQ2 encoder (not included) and assistance with
understanding some details of the format.
Decode the Image Data Section (which contains merged pictures).
Support RGB/A and Grayscale/A in 8bits and 16 bits per channel.
Support uncompress and rle decompression in Image Data Section.
