Renamed gst_va_decoder_set_format() to
gst_va_decoder_set_frame_size_with_surfaces() which resembles better
the passed parameters. Internally it creates the vaContext.
Added gst_va_decoder_set_frame_size() which is an alias of
gst_va_decoder_set_frame_size_with_surfaces() without surfaces. This
is the function which replaces gst_va_decoder_set_format() where
used.

We should use the NumPocTotalCurr value stored in decoder, which is a calculated
valid value, rather than use the invalid value in the slice header. Most of the
time, the NumPocTotalCurr is 0 and make the tmp_refs a very short length, and
causes the decoder's wrong result.
By the way, the NumPocTotalCurr is not the correct name specified in H265 spec,
its name should be NumPicTotalCurr. We change it to the correct name.

Some GPUs support BGRA format and it will be converted to subsampled
YUV format by GPU internally. Disable this implicit conversion
since the conversion parameters such as input/output colorimetry
are not exposed nor it's written in bitstream (e.g., VUI).
We prefer explicit conversion via our conversion elements.

Some manifests use the ContentProtection node to store additional information
such as the license server url. Our MPD parser used to process the
ContentProtection node, extracting Playready PSSH boxes. However for other DRM
systems, only the `value` attribute was passed down to the protection event, so
for example, Widevine data was not parsed at all and "Widevine" was passed to
the event, which is not very useful for decryptors that require a PSSH init
data.
Parsing should now be done by decryptors which will receive the entire
ContentProtection XML node as a string. This gives more "freedom" to the
decryptor which can then detect and parse custom nodes as well.

The VP9 streams have the ability to change the resolution dynamically
at any time point. It does not send ad KEY frame before change the
resolution, even the INTER frame can change the resolution immediately.
So we need to check the resolution change for each frame and do the
re-negiotiation if needed.
Some insaned stream may play in resolution A first and then dynamically
changes to B, and after 1 or 2 frames, it use a show_existing_frame to
repeat the old frame of resolution A before. So, not only new_picture(),
but also duplicate_picture() need to check this.

Some codecs such as VP9, its config and context have the ability to
dynamically. When we only change the width and height, no need to
re-create the config and context. The helper function can just change
the resolution without re-creating config and context.

When the muxer is operating in VBR mode, it's kind of expected
for now that we might not put the PCR in exactly the right place,
because the muxer doesn't schedule packets that way. In that case
don't warn constantly about the PCR ending up a few ms off target.

The spec mandates this field be parsed using unsigned arithmetic. Nevertheless,
av1parser will use -1 apparently as an uninitialized value in
gst_av1_parse_frame_header. This immediately underflows last_frame_idx
though, since its type was defined as guint8. Fix this by converting to gint8.

When the sink goes from PLAYING to READY and then back to PLAYING,
the initialization of the audioclient in prepare() fails with the
error AUDCLNT_E_ALREADY_INITIALIZED. As a result, the playback
stops.
To fix this, we need to drop the AudioClient in unprepare() and
grab a new one in prepare() to be able to initialize it again
with the new buffer spec.

The functionality now resides in
gst_wasapi_util_get_device() and
gst_wasapi_util_get_audio_client().
This is a preparatory patch. It will be used in the following
patch to init/deinit the AudioClient separately from the device.

failure to pass a display in 'handle' would result in uninitialized value
being returned, which would often segfault later down the road when trying
to initialize gstreamer context with it.
Check the return value of gst_structure_get() to make sure we return valid
data.
Furthermore, the gstglimagesink in gst-plugins-base also has a similar
mechanism but uses 'display' as field name to pass the value; instead of
requiring the application to behave differently depending on what sink
was automatically detected just try to read both values here, with display
being the new default.

The current setting of color properties are not very correct and
we will get some kind of "unknown Color Standard for YUV format"
warnings printed out by drivers. The video-color already provides
some standard APIs for us, and we can use them directly.
We also change the logic to: Finding the exactly match or explicit
standard first. If not found, we continue to find the most similar
one.

There may be leading frames after the IRAP frames, which has negative
POC. This kind of frames are allowed and they will be displayed before
the IRAP frame. So the warning should not be triggered for them. Init
the last_output_poc to G_MININT32 can avoid this.

Qualcomm GPU works fine with current implementation now.
Noticeable difference between when it was disabled and current
d3d11 implementation is that we now support GstD3D11Memory
pool, so there will be no more frequent re-binding decoder surface anymore.
