1e7c4db5a7 Add initial support for EGL.
Add initial support for EGL to libgstvaapi core library. The target
display server and the desired OpenGL API can be programmatically
selected at run-time.

A comprehensive set of EGL utilities are provided to support those
dynamic selection needs, but also most importantly to ensure that
the GL command stream is executed from within a single thread.

d48ab9a3d6 Encode: Add support for Picture level Entrypoint
This is useful for JPEG encoding which is utilizing picture level
entrypoint instead of slice level entrypoint like h264,mpeg2 etc.

807c4e8248 display: add utility function to check for OpenGL rendering.
Add gst_vaapi_display_has_opengl() helper function to help determining
whether the display can support OpenGL context to be bound to it, i.e.
if the class is of type GST_VAAPI_DISPLAY_TYPE_GLX.

7d5d3e8640 display: refine the meaning of display type.
Make gst_vaapi_display_get_display_type() return the actual VA display
type. Conversely, add a gst_vaapi_display_get_class_type() function to
return the type of the GstVaapiDisplay instance. The former is used to
identify the display server onto which the application is running, and
the latter to identify the original object class.

1843774c0b display: record native display object.

underlying native display, e.g. for creating an EGL display.

7c2c4c7a97 display: add interface to retrieve the display name.

the name associated with the underlying native display. Note that for
raw DRM backends, the display name is actually the device path.

c0993182bd display: add utility function to query VA driver name.
Add gst_vaapi_display_get_vendor_string() helper function to query
the underlying VA driver name. The display object owns the resulting
string, so it shall not be deallocated.

That function is thread-safe. It could be used for debugging purposes,
for instance.

71053228b3 display: make cache maintenance really MT-safe.
Make sure to initialize one GstVaapiDisplay at a time, even in threaded
environments. This makes sure the display cache is also consistent
during the whole display creation process. In the former implementation,
there were risks that display cache got updated in another thread.

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.

51151e7aa1 Add initial support for GStreamer 1.0.
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.

8ebe4d63d5 display: fix validation process of properties during discovery.
Some VA drivers (e.g. EMGD) can have completely random values for initial
display attributes. So, try to improve the discovery process to check the
initial display attribute values actually fall within valid bounds. If not,
try to reset those to some sensible values like the default value reported
through vaQueryDisplayAttributes().

a192f40ed9 display: add support for rendering modes.
A rendering mode can be "overlay" or "texture"'ed blit.

The former mode implies that a VA surface used for rendering can't be
re-used right away for decoding, so the sink shall make provisions to
retain the associated surface proxy until the next surface is to be
displayed.

The latter mode implies that the VA surface is implicitly copied to an
intermediate backing store, or back buffer of a frame buffer, so the
associated surface proxy can be disposed right away.
