As part of the upstreaming process of gstreamer-vaapi into the GStreamer
umbrella, we need to comply with the project's code style. This meant to
change a lot of code.
It was decided to use a single massive patch to update the code style.
I would like to apologize with the original developers of this code because of
the history breakage.

Don't expose functions that reference a GstVaapiImageRaw, those are
meant to be internal only for implementing subpictures sync. Also add
a few private definitions to avoid functions calls for retrieving
image size and format information.
Drop obsolete GST_VAAPI_IS_xxx() helper macros since we are no longer
deriving from GObject and so those were only checking for whether the
argument was NULL or not. This is now irrelevant, and even confusing
to some extent, because we no longer have type checking.
Note: this incurs more type checking (review) but the libgstvaapi is
rather small, so this is manageable.
This integrates support for GStreamer API >= 1.0 only in the libgstvaapi
core decoding library. The changes are kept rather minimal here so that
the library retains as little dependency as possible on core GStreamer
functionality.

Use newer gst_video_overlay_rectangle_get_pixels_unscaled_raw() helper
function with GStreamer 0.10 compatible semantics, or that tries to
approach the current meaning. Basically, this is also just about moving
the helper to gstcompat.h.
Handle global-alpha from GstVideoOverlayComposition API. Likewise,
the same code path could also work for premultiplied-alpha but this
was not tested.

Add the necessary helpers in GstVaapiDisplay to determine whether subpictures
with global alpha are supported or not. Also add accessors in GstVaapiSubpicture
to address this feature.

This is a preferred thread-safe version. Also add an inline version of
g_clear_object() if compiling with glib < 2.28.
