The support for GStreamer 1.0 has been obsoleted in 0.5.10 release.
GStreamer 1.2 is the a minimal requirement for building the gstreamer-vaapi.
This patch removes all the pre-processor conditional code compilation guarded
for gstreamer-1.0.
Thus, all the video converters were removed too.

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 Since gstreamer-0.10 is obsolete, the code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

Add initial support for EGL through GstVideoGLTextureUploadMeta.
Fix gst_vaapi_ensure_display() to allocate a GstVaapiDisplay off the
downstream supplied GstGLContext configuration, i.e. use its native
display handle to create a GstVaapiDisplay of type X11 or Wayland ;
and use the desired OpenGL API to allocate the GstVaapiDisplayEGL
wrapper.

Allow v4l2src element to connected to vaapipostproc or vaapisink when
"io-mode" is set to "dmabuf-import". In practice, this is a more likely
operational mode with uvcvideo. Supporting v4lsrc with "io-mode" set
to "dmabuf" could work, but with more demanding driver or kernel reqs.
Note: with GStreamer 1.4, v4l2src (gst-plugins-good) needs to be built
with --without-libv4l2.

Reword surface pool allocation helpers so that to allow for a simple
form, e.g. gst_vaapi_surface_pool_new(format, width, height); and a
somewhat more elaborated/flexible form with optional allocation flags
and precise GstVideoInfo specification.
This is an API/ABI change, and SONAME version needs to be bumped.
Add GST_VAAPI_VIDEO_BUFFER_POOL_ACQUIRE_FLAG_NO_ALLOC params flag that
can be used to disable early allocations of vaapi video metas on buffers,
thus delagating that to the bufferpool user.
Always add VideoAlignment bufferpool option if the downstream element
expects its own pool to be used but does not offer it through a proper
propose_allocation() implementation for instance, and that the ALLOCATION
query does not expose the availability of the Video Meta API.
This fixes propagation of video buffer stride information to Firefox.
Requesting the GLTextureUpload meta on buffers in the bufferpool
prevents such metas from being de-allocated when buffers are released
in the sink.
This is particulary useful in terms of performance when using the
GLTextureUploadMeta API since the GstVaapiTexture associated with
the target texture is stored in the meta.

Reset the buffer pool allocator only if the config caps changed in a
sensible way: format or resolution change. i.e. don't bother with
other caps like colorimetry et al. as this doesn't affect the way to
allocate VA surfaces or images.
Fix GstVaapiVideoBufferPool::reset_buffer() to reset the underlying
memory resources, and more particularly the VA surface proxy. Most
importantly, the GstVaapiVideoMeta is retained. Cached surface in
memory are released, thus triggering a new allocation the next time
we need to map the buffer.
If the video buffer pool config doesn't have new caps, then it's not
necessary to reinstantiate the allocator. That could be a costly
operation as we could do some extra heavy checking in there.
Implement GstVideoMeta::{,un}map() to support raw YUV buffer upload when
the last component is unmapped. Downloads are not supported yet. The aim
was to first support SW decoding + HW accelerated rendering (vaapisink).
e.g. for Wayland.
Add initial support for GstVaapiVideoMemory backed buffer pool. The memory
object currently holds a reference to GstVaapiVideoMeta.
