The whole libgstvaapi libraries got a major refresh to get rid of GObject.
This is a fundamental change that requires a new SONAME. More changes are
underway to streamline the core libraries.
So far, the net result is a reduction of .text size (code) by 32KB, i.e. -10%.
On one particular test (sintel HD trailer), the total number of executed
instruction was reduced by 8%.
Ensure libgstvaapi-glx*.so builds against libdl since dlsym() is used
to resolve glXGetProcAddress() from GLX libraries. This fix builds on
Fedora 17.

Bump library major version, while preserving a major version of 0 for
GStreamer 1.0 based libraries, and a major version of 2 for GStreamer
0.10 based librarieS.
Introduce a new configure option --with-gstreamer-api that determines
the desired GStreamer API to use. By default, GStreamer 1.0 is selected.
Also integrate more compatibility glue into gstcompat.h and plugins.
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.

GstVideoDecoder API is part of an unreleased GStreamer 0.10 stack. In particular,
this is only available in git 0.10 branch or GStreamer >= 1.0 stack. Interested
parties may either use upstream git 0.10 branch or backport the necessary support
for GstVideoDecoder API, thus including helper tools like GstVideoCodecFrame et al.
If GST_PLUGIN_PATH environment variable exists and points to a valid
directory, then use it as the system installation path for gst-vaapi
plugin elements.

Invoke gst_mpeg_video_finalise_mpeg2_sequence_header() to get the
correct PAR values. While doing so, require a newer version of the
bitstream parser library.
Note: it may be necessary to also parse the Sequence_Display_Extension()
header.

This patch updates to relect the 1.0 version of the protocol. The main
changes are the switch to wl_registry for global object notifications
and the way that the event queue and file descriptor is processed.

Use newer sources from the codecparsers/ submodule for
- GstH264SliceHdr.n_emulation_prevention_bytes: EPBs;
- GstH264VUIParams.{par_n,par_d}: pixel-aspect-ratio.
vaapisink is now built with support for multiple display types, whenever
they are enabled. The new "display" attribute is used to select a particular
renderer.
This flag is obsolete. It was meant to explicitly enable/disable VA/GLX API
support, or fallback to TFP+FBO if this API is not found. Now, we check for
the VA/GLX API by default if --enable-glx is set. If this API is not found,
we now default to use TFP+FBO.
Note: TFP+FBO, i.e. using vaPutSurface() is now also a deprecated usage and
will be removed in the future. If GLX rendering is requested, then the VA/GLX
API shall be used as it covers most usages. e.g. AMD driver can't render to
an X pixmap yet.
