This fixes frame corruption issue when decoder started reusing frames
while they are still in use of encoding process

Issue with frame corruption  was reproduced using:

    avconv.exe -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i input.h264 -an -c:v h264_amf output.mkv

It is recommended to use -extra_hw_frames 16 option in case if hw frames
number in pool is not enough

This fixes building with clang in msvc mode, which does support
gcc style inline assembly.

This removes the XP compatibility code, and switches entirely to SRW
locks, which are available starting at Windows Vista.

This removes CRITICAL_SECTION use, which allows us to add
PTHREAD_MUTEX_INITIALIZER, which will be useful later.

Windows XP is hereby not a supported build target anymore.

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).

Starting from API 1.25 helps to improve performance of the simultaneous

    -filter_complex "split=2[s1][s2]; [s1]scale_qsv=1280:720[o1];
[s2]scale_qsv=960:540[o2]" \
    -map [o1] -c:v h264_qsv -b:v 3200k -minrate 3200k -maxrate 3200k -f
rawvideo /tmp/3200a.264 \
    -map [o2] -c:v h264_qsv -b:v 1750k -minrate 1750k -maxrate 1750k -f

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.

AMFTraceWriter is an abstraction to configure how AMF outputs its logs
for the current process and can be configured to output different levels
of trace output. If multiple LibavWriter objects are used in one process,
there will be duplication of output in av_log. Use a constant writer_id
to prevent this scenario.

Deletes both filler NAL units and filler SEI messages.  (Annex B zero_bytes
between NAL units are already discarded by the read/write process.)

It's very large, and is only used in some FMO streams.

This should be added even if the first access unit does not contain
parameter sets.

This makes it easier for users of the CBS API to get alloc/free right -
all subelements use the buffer API so that it's clear how to free them.
It also allows eliding some redundant copies: the packet -> fragment copy
disappears after this change if the input packet is refcounted, and more
codec-specific cases are now possible (but not included in this patch).

If there is exactly one possible SPS but it is not yet active then just
assume that it should be the active one.

This is harmless and should not be a warning - unknown units are passed
through to the write functions unchanged, and no other code will interact
with them.

The iHD driver looks at entries beyond num_ref_idx_l[01]_active_minus1
for unknown reasons.

The buffers are created associated with the context, so they should be
destroyed before the context is.  This is enforced by the iHD driver.

This removes the arbitrary limit on the allowed number of slices and
parameter buffers.

Also fix conversion specifiers used for the unit type.

... instead of making callers allocate it themselves.  This is more
consistent with other APIs in libav.

This number is definitely required when frame threading is enabled, so
add it here rather than forcing all users to handle it themselves.

DXVA2 contained this addition in specific code as well (therefore being
added twice in the internal case) - just remove it from there.

AVCodecContext.extra_hw_frames is added to the size of hardware frame
pools created by libavcodec for APIs which require fixed-size pools.
This allows the user to keep references to a greater number of frames
after decode, which may be necessary for some use-cases.

It is also added to the initial_pool_size value returned by
avcodec_get_hw_frames_parameters() if a fixed-size pool is required.

This makes sure that consumers of the side data actually can
rely on the padding as intended, without having the callers of
av_packet_new_side_data to explicitly zero initialize it.
