Move display types from gstvaapipluginutil.* to gstvaapidisplay.* so that
we could simplify characterization of a GstVaapiDisplay. Also rename "auto"
type to "any", and add a "display-type" attribute.
This improves display name comparisons by always allocating a valid display
name. This also helps to disambiguate lookups by name in the global display
cache, should a new backend be implemented.
The vdeo buffer creation routines shall actually be internal to gstreamer-vaapi
plugin elements. So deprecate any explicit creation routines that are not the
new *_typed_new*() variants.
Introduce new typed constructors internal to gstreamer-vaapi plugin elements.
This avoids duplication of code, and makes it possible to further implement
generic video buffer creation routines that automatically map to base or GLX
variants.
If GLX window was created from a foreign Display, then that same Display shall
be used for subsequent glXMakeCurrent(). This means that gl_create_context()
will now use the same Display that the parent, if available.
This fixes cluttersink with the Intel GenX VA driver.
This flag is obsolete.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 codecparsers-based decoders are the only supported decoders now.
Though, FFmpeg decoders are still available in gstreamer-vaapi 0.3.x series.
This is a preferred thread-safe version. Also add an inline version of
g_clear_object() if compiling with glib < 2.28.

Add valid flag to GstJpegQuantTable and GstJpegHuffmanTable so that
to determine whether a table actually changed since the last user
synchronization point. That way, this makes it possible for some
hardware accelerated decoding solution to upload only those tables
that changed.
Add new GstJpegHuffmanTables helper structure to hold all possible
AC/DC Huffman tables available to all components.

gst_jpeg_parse() now gathers all scans available in the supplied
buffer. A scan comprises of the scan header and any entropy-coded
segments or restart marker following it. The size and offset to
the associated data (ECS + RST segments) are append to a new
GstJpegScanOffsetSize structure.

Improve generation of presentation timestamps to be less sensitive
to input stream errors. In practise, GOP is also a synchronization
point for PTS calculation.

TRD and TRB fields are not large enough to hold the difference of PTS
expressed with nanosecond resolution. So, compute them from the original
VOP info.
