VAProcColorStandardExplicit and associated VAProcColorProperties
(primaries, transfer and matrix) are not supported until
VA-API 1.2.0.
Use VAProcColorStandardNone instead of VAProcColorStandardExplicit
if VA-API < 1.2.0.
Fixes#231
Addresses #228 on iHD side. It seems iHD can't handle
VAProcColorStandardSRGB in all situations for vpp. But
it has no problem when we specify the sRGB parameters
via VAProcColorStandardExplicit parameters.
The return value of vaGetConfigAttributes() of VAConfigAttribRTFormat
is a bitwise flag with *all* the supported chroma types.
Previously it was assumed that the return value was a single value,
thus when returning the GST_VAAPI_CHROMA_TYPE_XXX the code was a
simple case. But it is wrong.
This patch changes the case block with a sequence of ifs testing the
bitwise. For now we assume a "priority" list in the testing sequence.
When set multiple settings of color balance like hue, saturation,
brightness and contrast for vaapipostproc, they should be set as
parameters of color balance filter, at the same color balance
filter calling.
Otherwise, multiple color balance filter calling will cause
previous setting get reset by the last calling with default value.
Fixes#182.

ICQ is Intelligent Constant Quality. It will use the initial QP
vaule of icq-quality-factor to adjust QP at MB level intelligently
to improve subjective quality.
QVBR is Quality defined VBR. It will use qvbr-quality-factor to
adjust QP for each MB to get enough quality picture without waste
of bits.
Adds vpp mirroring support to vaapipostproc. Use
property video-direction. Valid values are identity,
horiz or vert. Default is identity (no mirror).
Closes#89
v2: Use GstVideoOrientationMethod enum
v3: Don't warn for VA_MIRROR_NONE.
Use GST_TYPE_VIDEO_ORIENTATION_METHOD type.
v4: Query VAAPI caps when setting mirror value
instead of during per-frame processing.
v5: Return TRUE in warning cases when setting mirror value.
string_of_va_chroma_format() gets a wrong string format description.
For example, the YUV420_10BPP get a string of 0x00000100 as output.
It's because VA_RT_FORMAT_xxx values are macro definitions. And
STRINGIFY(VA_RT_FORMAT_xxx) will expand to its real value
0x00000XXX.
To avoid the macro evaluation, it is changed to show only the color
format without VA_RT_FORMAT_ prefix.
Add more kinds of chrometype which will be used to describe
new video formats. Sync it with 1.4.0 version header file.
Alse delete useless GST_VAAPI_CHROMA_TYPE_YUV410 chrome type.

Add 422 10bit yuv format Y210, which can be used to decode
main-10-422 10bit streams. Currently, this feature is only
supported by media-driver in Icelake.

gstreamer-vaapi initializes the display by trial-and-error, thus
logging an error message if the display initialisation fails the user
may be weary of the error message in the screen, if using VA-API 1.0
This commit set the VA error log handler to GStreamer warning level
while calling vaInitialize() and set it to error after that.

Instead of initialize the chroma_type with a undefined value, which
will be converted to GST_VAAPI_CHROMA_TYPE_YUV420 by GstVaapiContext,
this patch queries the VA config, given the received
GstVaapiContextInfo's parameters, and gets the first response.
In order to get the GstVaapiChromaType value, also it was needed to
add a new utility function: to_GstVaapiChromaType(), which, given a
VA_RT_FORMAT_* will return the associated GstVaapiChromaType.

Redirect libva's logs to GStreamer logging mechanism. This is
particularly useful when VA is initialized, because it always logs
out the drivers details.
In order to achieve this a new helper function was added as a wrapper
for the vaInitialize() function.

Request the correct chroma format for decoding grayscale streams.
i.e. make lookups of the VA chroma format more generic, thus possibly
supporting more formats in the future.
This means that, if a VA driver doesn't support grayscale formats,
it is now going to fail. We cannot safely assume that maybe grayscale
was implemented on top of some YUV 4:2:0 with the chroma components
all set to 0x80.
