This allows the usage of codecs in builds that have a parser but no decoders
for remuxing scenarios with raw sources.

Also remove the _minus8 part of the name to be in line with the rest of the
decoder, and fix the storage type for pps_palette_predictor_initializer,
to support hbd values.

Support pixel formats 0x11412100, 0x11311100, and 0x41211100, and add
logic to perform 4x horizontal upsampling. This should fix various JPEG
files found in Ticket #8930.

- qsv_internal.h: Remove unnecessary include va_drm.h
- qsv_internal.h: Enable AVCODEC_QSV_LINUX_SESSION_HANDLE on Linux/VA only
- hwcontext_qsv.c: Do not allow child_device_type VAAPI for Windows until
support is added, keep D3D11/DXVA2 as more prioritary defaults.

framebuf is only allocated when the new width/height are larger than the old
but nothing sets the old so its always allocated.
Use av_fast_mallocz() instead.

The change introduced in b18a9c2971
created a regression for non-subsampled progressive RGB jpegs. This
should fix that.
Additionally, this should fix other RGB JPEGs broken before the recent
patches, such as those in Trac issue #10190.
The decoder is tagged as being FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM, so might as
well make use of it.

A single smvjpeg packet decodes into one large mjpeg frame, slices of
which are then returned as output frames. Packet duration covers all of
these slices.
Current code prefers deprecated AVFrame.pkt_duration over its
replacement AVFrame.duration whenever the former is set and not equal to
the latter. However, duration will only be actually used when the
caller sets the AV_CODEC_FLAG_FRAME_DURATION flag, which was added
_after_ AVFrame.duration.
This implies that any caller aware of AV_CODEC_FLAG_FRAME_DURATION is
also aware of AVFrame.duration. pkt_duration should then never be used.
Commit b18a9c2971 introduced a regression
that broke some baseline RGB jpegs. (See Trac issue #4045). This fixes
that.
