GPU copy enables or disables GPU accelerated copying between video
and system memory. This may lead to a notable performance improvement.
Memory must be sequent and aligned with 128x64.

MSDK does not create internal acceleration device on Linux,
So MFXVideoCORE_SetHandle() is necessary.
It has been added for ff_qsv_init_session_device().
But missed for ff_qsv_init_internal_session() due to commit
1f26a23 overwrited commit db89f45Fix#7030
Signed-off-by: Zhong Li <zhong.li@intel.com>
Using MSDK parser can improve qsv decoder pass rate in some cases (E.g:
sps declares a wrong level_idc, smaller than it should be).
And it is necessary for adding new qsv decoders such as MJPEG and VP9
since current parser can't provide enough information.
Actually using MFXVideoDECODE_DecodeHeader() was disscussed at
https://ffmpeg.org/pipermail/ffmpeg-devel/2015-July/175734.html and merged as commit 1acb19d,
but was overwritten when merged libav patches (commit: 1f26a23) without any explain.
Split decode header from decode_init, and call it for everyframe to
detect format/resoultion change. It can fix some regression issues such
as hevc 10bits decoding.

It is helpful to know why some clips decoding failed.
Ticket#7330 is a good example, with this patch it is easily to
know bitstream codec level is out of support range.

Assertion avctx->codec_id != AV_CODEC_ID_NONE failed at src/libavcodec/parser.c:128
The setting on the internal AVCodecContext used for parsing only is
otherwise irrelevant, so just set it to avoid the assert.
Flush the buffered data in libmfx before video param reinit
in case the frames drop.
Cache the first frame causing the reinit and decode zero-size
pkt to flush the buffered pkt before reinit. After all the
buffered pkts being flushed, resume to reinit and decode.
Fix the issue in ticket #7399.
[V2]: Move the definition of zero_pkt to where it is exactly
used.

Current implementations of qsv components incorrectly work with async level, they
actually try to work in async+1 level stepping into MFX_WRN_DEVICE_BUSY and polling
loop. This change address this misbehaviour.

lavc/qsvdec: set complete_frame flags for progressive picture
Merged-by: James Almer <jamrial@gmail.com>
Set the flag MFX_BITSTREAM_COMPLETE_FRAME when it is a progressive picture.
This can fix vc1 decoding segment fault issues because can't set the start
code correctly.
See: ./avconv -hwaccel qsv -c:v vc1_qsv -i /fate-suite/vc1/SA00040.vc1
-vf "hwdownload, format=nv12" -f rawvideo /dev/null
v2: fix some h264 interlaced clips regression
a. field_order of some h264 interlaced video (e.g: cama3_vtc_b.avc) is marked as AV_FIELD_UNKNOWN
in h264_parser.c. This is not a completed frames.
So only set the MFX_BITSTREAM_COMPLETE_FRAME when it is progressive.
b. some clips have both progressive and interlaced frames (e.g.CAPAMA3_Sand_F.264),
the parsed field_order maybe changed druing the decoding progress.
This patch has been verified for other codecs(mpeg2/hevc/vp8).

Currently pict_type and key_frame are unset.
Add an extra param to fetch the picture type from qsv decoder
The judgement “key frame is equal to IDR frame” only suitable for H264.
For HEVC, all IRAP frames are key frames, and other codecs have no IDR
frame.

Fix a common vp8 decoding failure.
Many vp8 clips cannot decode if hw_frames_ctx is enabled, reporting
"Error during QSV decoding.: incompatible video parameters (-14)".
It is due to mfx.FrameInfo.Width/Height not matching coded_w/coded_h.

This includes a pointer to the associated hwaccel for decoders using

Also added is a new file listing all hwaccels as external declarations -
this will be used later to generate the hwaccel list at configure time.

qsvdec: only access hwaccel_context is the pixel format is QSV
Merged-by: Clément Bœsch <u@pkh.me>
Introducing enforced sync points in arbitrary places is bad for
performance. Since the vast majority of receiving code (QSV VPP or
encoders, retrieving frames through hwcontext) will do the syncing, this
change should not be visible to most callers. But bumping micro just in
case.
This is also consistent with what VAAPI hwaccel does.
This was correct for H.26[45], because libmfx uses the same values
derived from profile_idc and the constraint_set flags, but it is
wrong for other codecs.
Also avoid passing FF_LEVEL_UNKNOWN (-99) as the level, as this is
certainly invalid.
