VA-API HEVC decoding needs to known which is the last slice of a
picture, but slices are processed sequencially, so we know the
last slice until all the slices are already pushed into the
VABuffer array.
In order to mark the last slice, they are pushed into the
VABuffer array with a delay of one slice: the first slice is
hold, and when the second slice come, the first one is pushed
while holding the second, and so on. Finally, at end_picture(),
the last slice is marked and pushed into the array.

The VA acceleration now has more usages in linux-like platforms,
such as the MSDK. The different plugins based on the VA acceleration
need to share some common logic and types. We now move the display
related functions and types into a common va lib.

The VP9 related definitions in mfxvp9.h are available under the
condition of 'MFX_VERSION >= MFX_VERSION_NEXT', which implies that these
definitions are never used in a public release.
This is in preparation for oneVPL support because mfxvp9.h was
removed from oneVPL

We have only one copy of gst_va_base_dec_parent_class inside the
vabasedec, so it can not handle the case when there are multi va
decoders inside one pipeline. The pipeline:
gst-launch-1.0 filesrc location=xxx.h264 ! h264parse \
! vah264dec ! msdkh265enc ! vah265dec ! fakesink
generates a assertion of
"invalid cast from 'GstVaH264Dec' to 'GstH265Decoder"
and gets a crash.
We should keep the parent_class for each decoder type.

VADecPictureParameterBufferAV1.mode_control_fields.bits were filled
twice, overwriting to zeros the first assignation. This patch unifies
both assignations.
Also it makes explicit an enum casting between libva and gstreamer; it
removes the assignation to zero a deprecated parameter; and use an
appropriate assertion.

Before creating output duplication interface, call SetThreadDesktop()
with HDESK of the current input desktop in case a desktop switch has
occurred.
This allows d3d11desktopdupsrc to capture Windows User Account Control
(UAC) prompts, which appear on a separate secure desktop. Otherwise
IDXGIOutput1::DuplicateOutput() will return E_ACCESSDENIED and the
element won't produce any frames as long as the UAC screen is active.
Note that in order to access secure desktop the application still has to
run at LOCAL_SYSTEM privileges. For GStreamer applications running with
regular user privileges this change has no effect.

IDXGIOutputDuplication can become invalid for example when there's
desktop switch, resolution change or Windows User Account Control prompt
appears on screen.
When that happens, try to re-create the duplication interface for the
changed output. Note that in the case of UAC prompt this operation will
fail if the GStreamer process doesn't run at LOCAL_SYSTEM privileges. In
such situation the source element won't create any frames as long as the
output is occupied by UAC screen.
In order to enable UAC access to sufficiently privileged GStreamer
processes, call SetThreadDesktop() with the desktop handle that
currently receives user input before creating our output duplication.

The problem is for uploading YUV frames using derived images, is that
derived images imply tiling, so frames are wrongly uploaded.
Though derived for reading might work we cannot know the Intel graphics
generation to validate the caching. Overall, it's safer to disable derived
images for i965.

iHD driver sets a tiled DRM modifier if surface's usage hint is set to
VPP_WRITE. This result in a garbled rendering when using glimagesink.
This patch changes the usage hint to generic if the caps feature is
DMABuf. Either way only iHD driver, so far, uses the usage hint flag.

Some capture devices might not provide channel mask value which will
result in capturing failure because of unknown channel mask in case
that device generates more than 2 channels. Although it might not
be correct, we can assume channel mask with the given number of channels.
