38f8fea4bb guard buffer export API if not available
The support for buffer exports in VA-API was added in version 0.36. These
interfaces are for interop with EGL, OpenCL, etc.

GStreamer-VAAPI uses it for a dmabuf memory allocator. Though, gstreamer-vaapi
has to support VA-API versions ranging from 0.30.4, which doesn't support it.

This patch guards all the buffer exports handling (and dmabuf allocator) if
the detected VA-API version is below 0.36.

dd37fc4999 surface: add initial support for foreign buffer imports.
Add gst_vaapi_surface_new_from_buffer_proxy() helper function to
create a VA surface from an external buffer provided throug the
new GstVaapiBufferProxy object.

4ebfba0d49 surface: add more fine-grained allocation helper.
Add new gst_vaapi_surface_new_full() helper function that allocates
VA surface from a GstVideoInfo template in argument. Additional flags
may include ways to
- allocate linear storage (GST_VAAPI_SURFACE_ALLOC_FLAG_LINEAR_STORAGE) ;
- allocate with fixed strides (GST_VAPI_SURFACE_ALLOC_FLAG_FIXED_STRIDES) ;
- allocate with fixed offsets (GST_VAAPI_SURFACE_ALLOC_FLAG_FIXED_OFFSETS).

3b714c8913 context: move overlay composition to separate files.
Move GstVideoOverlayComposition handling to separate source files.
This helps keeing GstVaapiContext core implementation to the bare
minimal, i.e. simpy helpers to create a VA context and handle pool
of associated VA surfaces.

33bb859228 Fix printf()-like formats.
Fix formts for various GST_DEBUG et al. invocations. More precisely,
make size_t arguments use the %zu format specifier accordingly; force
XID formats to be a 32-bit unsigned integer; and fix the format used
for gst_vaapi_create_surface_with_format() error cases since we have
been using strings nowadays.

2b0a4a0304 image: clean image API up.
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.

GStreamer 0.10 builds.

7fa4973f8a Fix new video format API.
Fix new internal video format API, based on GstVideoFormat, to not
clobber with system symbols. So replace the gst_video_format_* prefix
with gst_vaapi_video_format_ prefix, even if the format type remains
GstVideoFormat.

8663ad9492 surface: try to determine the underlying VA surface format.
If a VA surface was allocated with the chroma-format interface, try to
determine the underlying pixel format on gst_vaapi_surface_get_format(),
or return GST_VIDEO_FORMAT_ENCODED if this is not a supported operation.

a1b27c920b surface: allow creation with explicit pixel format.
Make it possible to create VA surfaces with a specific pixel format.
This is a new capability brought in by VA-API >= 0.34.0. If that
capability is not built-in (e.g. using VA-API < 0.34.0), then
gst_vaapi_surface_new_with_format() will return NULL.

d633e0d072 surface: add new chroma formats.
Add new chroma formats available with VA-API >= 0.34.0. In particular,
this includes "RGB" chroma formats, and more YUV subsampled formats.
Also add a new from_GstVaapiChromaType() helper function to convert
libgstvaapi chroma type to VA chroma format.

99dfd44f33 surface: add simple surface info accessors as helper macros.
Add helper macros to retrieve the VA surface information like size
(width, height) or chroma type. This is a micro-optimization to avoid
useless function calls and NULL pointer re-checks in internal routines.

18031dc6ff surface: fix memory leak through unreleased parent context.
Break the circular references between GstVaapiContext and its children
GstVaapiSurfaces. Since the VA surfaces held an extra reference to the
context, which holds a reference to its VA surfaces, then none of those
were released.

How does this impact support for subpictures?

The only situation when the parent context needs to disappear is when
it is replaced with another one because of a resolution change in the
video stream for instance, or a normal destroy. In this case, it does
not really matter to apply subpictures to the peer surfaces since they
are either gone, or those that are left in the pipe can probably bear
a reinstantiation of the subpictures for it.

So, parent_context is set to NULL when the parent context is destroyed,
other VA surfaces can still get subpictures attached to them, individually
not as a whole. i.e. subpictures for surface S1 will be created from
active composition buffers and associated to S1, subpictures for S2 will
be created from the next active composition buffers, etc. We don't try
to cache the subpictures in those cases (pending surfaces until EOS
is reached, or pending surfaces until new surfaces matching new VA context
get to be used instead).

67eea92044 libs: drop GST_VAAPI_IS_xxx() helper macros.
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.

1cd4a8fc04 subpicture: add support for global-alpha.
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.
