a5650e8dc3 libs: utils: return NULL if failed to get surface formats 
Thus, when generating the allowed caps, the element will throw a
warning and it will use its caps template.

This behavior might be a bug in the VA driver.

d1581ba557 libs: move get_surface_formats to utils_core 
The query of all the supported formats for a VA config were only used by the
postprocessor (vaapifilter). But, in order to enable the vaapidecoder to
negotiate a suitable raw format with downstream, we need to query these
formats against the decoder's config.

This patch is the first step: moves the code in filter's ensure_image() to a
generic gst_vaapi_get_surface_formats() in vaapiutils_core, so it can be
shared later by the decoder.

db7a3b8d3e libs: factor out usages of vaGetConfigAttributes(). 
Add gst_vaapi_get_config_attribute() helper function that takes a
GstVaapiDisplay and the rest of the arguments with VA types. The aim
is to have thread-safe VA helpers by default.
