Working on bug #744042 I realized that the gstvaapiuploader is practically not
used.
This patch removes the gstvaapiuploader and add the method
gst_vaapi_plugin_base_get_allowed_raw_caps () that returns the raw caps that
the system can handle, which is used by vaapisink and vaapipostproc.

If a GstGLContext is supplied by the downstream element, then make
sure that the VA plugin element gets a compatible display to what
is requested by the GL context. e.g. re-allocate a VA/GLX display
when a GLX context is provided by the downstream element.
Record GL context supplied by downstream elements. This can be useful,
and further needed, to enforce run-time check that the GL context is
compatible for use by libgstvaapi. e.g. check that we don't create a
VA/GLX display for EGL/X11 contexts.

Add a default decide_allocation() hook to GstVaapiPluginBase. The caps
feature argument can be used to force a bufferpool with a specific kind
of memory.
Add a "display-name" property to vaapisink so that the end user could
select the desired output. Keep "display-name" in-line with the existing
"display" (GstVaapiDisplayXXX type).
So, for X11 or GLX, the "display-name" is the usual display name as we
know for XOpenDisplay(); for Wayland, the "display-name" is the name used
for wl_display_connect(); and for DRM, the "display-name" is actually the
DRI device name.

Factor out propose_allocation() hooks, creation of video buffer pool
for the sink pad, conversion from raw YUV buffers to VA surface backed
buffers. Update vaapidecode, vaapiencode and vaapipostproc to cope
with the new GstVaapiPluginBase abilities.
Move common VA display creation code to GstVaapiPluginBase, with the
default display type remaining "any". Also add a "display-changed"
hook so that subclasses could perform additional tasks when/if the
VA display changed, due to a new display type request for instance.
All plug-ins are updated to cope with the new internal APIs.
Introduce a new GstVaapiPluginBase object that will contain all common
data structures and perform all common tasks. First step is to have a
single place to hold VA displays.
While we are at it, also make sure to store and subsequently release
the appropriate debug category for the subclasses.
