6f2dfb71e6 plugins: factor out display creation process.
Move common VA display creation code to GstVaapiPluginBase, with the
default display type remaining "any". Also add a "display-changed"
hook so that subclasses could perform additional tasks when/if the
VA display changed, due to a new display type request for instance.

All plug-ins are updated to cope with the new internal APIs.

7e58d60854 plugins: add new base object, store display in there.
Introduce a new GstVaapiPluginBase object that will contain all common
data structures and perform all common tasks. First step is to have a
single place to hold VA displays.

While we are at it, also make sure to store and subsequently release
the appropriate debug category for the subclasses.

2f5e5f0784 encoder: clean-ups and document public APIs.
Clean public APIs up so that to better align with the decoder APIs.
Most importantly, gst_vaapi_encoder_get_buffer() is changed to only
return the VA coded buffer proxy. Also provide useful documentation
for the public APIs.

038149b69b encoder: refactor status codes.
Drop obsolete or unused status codes. Align some status codes with the
decoder counterparts.

0fb7c60508 encoder: rework GstVaapiCodedBuffer and related proxy.
Refactor the GstVaapiCodedBuffer APIs so that to more clearly separate
public and private interfaces. Besides, the map/unmap APIs should not
be exposed as is but appropriate accessors should be provided instead.

* GstVaapiCodedBuffer: VA coded buffer abstraction
- gst_vaapi_coded_buffer_get_size(): get coded buffer size.
- gst_vaapi_coded_buffer_copy_into(): copy coded buffer into GstBuffer

* GstVaapiCodedBufferPool: pool of VA coded buffer objects
- gst_vaapi_coded_buffer_pool_new(): create a pool of coded buffers of
  the specified max size, and bound to the supplied encoder

* GstVaapiCodedBufferProxy: pool-allocated VA coded buffer object proxy
- gst_vaapi_coded_buffer_proxy_new_from_pool(): create coded buf from pool
- gst_vaapi_coded_buffer_proxy_get_buffer(): get underlying coded buffer
- gst_vaapi_coded_buffer_proxy_get_buffer_size(): get coded buffer size

Rationale: more optimized transfer functions might be provided in the
future, thus rendering the map/unmap mechanism obsolete or sub-optimal.

7a33165436 plugins: fix reference leaks of VA display objects.
Fix GstElement::set_context() implementation for all plug-in elements
to avoid leaking an extra reference to the VA display, thus preventing
correct cleanup of VA resources in GStreamer 1.2 builds.

30f382fcdf vaapiencode: optimize _handle_frame() to avoid extra allocation.
Optimize gst_vaapiencode_handle_frame() to avoid extra memory allocation,
and in particular the GstVaapiEncObjUserData object. i.e. directly use
the VA surface proxy from the source buffer. This also makes the user
data attached to the GstVideoCodecFrame more consistent between both
the decoder and encoder plug-in elements.

081ff63f9a vaapiencode: fix memory leaks in _push_frame() on error.
Simplify gst_vaapiencode_push_frame(), while also removing the call
to gst_video_encoder_negotiate() since this is implicit in _finish()
if caps changed. Also fixed memory leaks that occured on error.

8116d8a50e vaapiencode: additional clean-ups.
Constify pointers wherever possible. Drop unused variables, and use
consistent variable names. Fix gst_vaapiencode_h264_allocate_buffer()
to correctly report errors, especially when in-place conversion from
bytestream to avcC format failed.

d759fe34e6 vaapiencode: move common properties to base class.
Move "rate-control" mode and "bitrate" properties to the GstVaapiEncode
base class. The actual range of supported rate control modes is currently
implemented as a plug-in element hook. This ought to be determined from
the GstVaapiEncoder object instead, i.e. from libgstvaapi.

unmap the coded buffer prior to returning an error.

a6b8f94470 vaapiencode: fix error handling in _finish() hook.
Fix GstVideoEncoder::finish() implementation to really return possible
errors instead of GST_FLOW_OK. That is, fix check for timeout status.

e01d48feba vaapiencode: minor clean-ups.
Add a GST_VAAPIENCODE_CAST() helper to avoid run-time checks against
the GObject type system. We are guaranteed to only deal with the same
plug-in element object.

84af151796 vaapiencode: fix support for raw YUV sink buffers.
Allow vaapiencode plug-in elements to encode from raw YUV buffers.
The most efficient way to do so is to let the vaapiencode elements
allocate a buffer pool, and subsequently buffers from it. This means
that upstream elements are expected to honour downstream pools.

If upstream elements insist on providing their own allocated buffers
to the vaapiencode elements, then it possibly would be more efficient
to insert a vaapipostproc element before the vaapiencode element.
This is because vaapipostproc currently has better support than other
elements for "foreign" raw YUV buffers.
