This patch fix the auto-plugging problem in gstreamer 1.2 and gstreamer 1.4
Right now there is not a primary ranked parser for vc1 and the demuxers
delivers caps without specifying the profile. This situation is not an issue
for avdec_vc1 but for vaapidecode it is, which refuses to negotiate without a
explicit profile defined in the negotiated caps.
Nonetheless, in gstreamer 1.5 it seems not to be a problem since the
negotiation admits caps subsets try outs.
This patch solves the issue ignoring the profile negotiation in the caps. For
gstreamer < 1.5 the profile string is not handled, so the auto-plugging get
done without the vc1 parser, such as happens in gstreamer 1.5.

The purpose of gstcompat.h is to couple the API differences among
gstreamer-1.0 and gstreamer-0.10. Since gstreamer-0.10 is obsolete, the code
in this compatibility layer shall be removed.
Nevertheless, the gstcompat.h header should be kept, if new incompatibilites
appear in the future, but it shall live in gst/vaapi, not in gst-libs.
This patch removes the crumbs defined gstcompat.h and moves it to gst/vaapi.
In order to avoid layer violations, gstcompat.h includes sysdeps.h and all
the includes in gst/vaapi of sysdeps.h are replaced with gstcompat.h

Recognize streams marked as conforming to the "Constrained Baseline
Profile". If VA driver supports that as is, fine. Otherwise, fallback
to baseline, main or high profile.
Constrained Baseline Profile conveys coding tools that are common
to baseline profile and main profile.

[Added fallbacks to main and high profiles]

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.

Use standard GstVideoCodecState throughout GstVaapiDecoder and expose
it with a new gst_vaapi_decoder_get_codec_state() function. This makes
it possible to drop picture size (width, height) information, framerate
(fps_n, fps_d) information, pixel aspect ratio (par_n, par_d) information,
and interlace mode (is_interlaced field).
This is a new API with backwards compatibility maintained. In particular,
gst_vaapi_decoder_get_caps() is still available.

HACK: qtdemux does not report profiles for H.263. So, assume plain
"video/x-h263" is H.263 Baseline profile.
