Add initial API for video encoding: only basic interfaces and small
encoder objects are implemented so far.

GstBitWriter provides a bit writer that can write any number of bits
to a pre-allocated memory buffer. Helper functions are also provided
to write any number of bits from 8, 16, 32 and 64 bit variables.

Automatically detect GStreamer API version. The --with-gstreamer-api
configure option now defaults to "autodetect" and configure then tries
to derive the GStreamer API version from the highest version based on
what pkg-config --modversion would report.

The GStreamer 1.2.x packages sticked to the naming convention for 1.0.x
packages, i.e. -1.0 suffix. However, for gstreamer-vaapi packaging
purposes, update the versioning to -1.2 suffix instead.
Port vaapidecode and vaapisink plugins to GStreamer API >= 1.2. This
is rather minimalistic so that to test the basic functionality.
Disable vaapipostproc plugin for now as further polishing is needed.
Also disable GstVideoContext interface support since this API is now
gone in 1.2.x. This is preparatory work for GstContext support.

Fix detection of VA/JPEG decoding API with non-standard libva packages.
More precisely, some packages were shipping with a <va/va.h> header that
did not include <va/va_dec_jpeg.h>.

Use hardware accelerated XRenderComposite() function, from the RENDER
extension, to blit a pixmap to screen. Besides, this can also support
cropping and scaling.
Bump the library major version due to API/ABI changes that occurred in
the imaging API. In particular, GstVaapiImageFormat type was replaced
with the standard GstVideoFormat type. All dependent APIs were updated
to match this change.
Add flag to have all codecparsers built-in, thus ensuring that the
resulting binaries have all the necessary bug fixes and this is what
the QA has been testing anyway.
Of course, for a completely up-to-date Linux distribution, you could
also opt for --disable-builtin-codecparsers and use the system ones.
Though, some core fixes could be missing, and those cannot be tested
for with API checks.
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

bitstream parser library.
Note: it may be necessary to also parse the Sequence_Display_Extension()
header.

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.
GStreamer -base plugins >= 0.10.31 are now required, so the checks for
new APIs like GstXOverlay::set_window_handle() and ::set_render_rectangle()
are no longer necessary.
GStreamer codecparsers-based decoders are the only supported decoders now.
Though, FFmpeg decoders are still available in gstreamer-vaapi 0.3.x series.
Also do not generate tamplate files as all the documentation is inline.
Drop un-needed code in autogen.sh as well.

Unlike what VA-API documentation defines, the slice_data_bit_offset
represents the offset to the first macroblock in the slice data, minus
any emulation prevention bytes in the slice_header().
This fix copes with binary-only VA drivers that won't be fixed any
time soon. Besides, this aligns with the current FFmpeg behaviour
that was based on those proprietary drivers implementing the API
incorrectly.
