libs: display: redirect logging at initialize 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. https://bugzilla.gnome.org/show_bug.cgi?id=777115

decoder: optimize slice data buffers initialization. VA drivers may have a faster means to transfer user buffers to GPU buffers than using memcpy(). In particular, on Intel Gen graphics, we can use pwrite(). This provides for faster upload of bitstream and can help higher bitrates. vaapi_create_buffer() helper function was also updated to allow for un-mapped buffers and pre-initialized data for buffers.

decoder: h264: properly support grayscale formats. 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.

libs: encoder: initialize chroma_type 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. https://bugzilla.gnome.org/show_bug.cgi?id=771291
