cb81acd48c vaapidecode: add system memory caps to template caps.
Since vaapidecode provides buffer that can be mapped as regular memory,
those caps should be added to the template caps. That only applies to
GStreamer >= 1.2.

d2f6274f31 vaapidecode: fix hang on SIGINT.
vaapidecode hangs when pipeline is stopped without any EOS, e.g. when
<Ctrl>+C is pressed, thus causing the srcpad task to keep running and
locked. This fixes a deadlock on state change from PAUSED to READY.

ef9819ecf4 plugins: add helpers to create video caps with features.
Add gst_vaapi_video_format_new_template_caps_with_features() helper
function to add the supplied caps feature string on GStreamer >= 1.2.

Add gst_vaapi_find_preferred_caps_feature() helper function to discover
the "best" caps feature to use for the supplied pad. In practice, we
will always favor memory:VASurface first, then meta:GLTextureUploadMeta,
and finally the system memory caps.

bdf91aa765 encoder: h264: allow target decoder constraints.
Allow user to precise the largest profile to use for encoding due
to target decoder constraints. For instance, if CABAC entropy coding
mode is requested by "constrained-baseline" profile only is desired,
then an error is returned during codec configuration.

Also make sure that the suitable profile we derived actually matches
what the HW can cope with.

5394c75461 encoder: add video codec-state API.
Add interface to communicate the encoder resolution and related info
like framerate, interlaced vs. progressive, etc. This new interface
supersedes gst_vaapi_encoder_set_format() and doesn't use any GstCaps
but rather use GstVideoCodecState.

Note that gst_vaapi_encoder_set_codec_state() is also a synchronization
point for codec config. This means that the encoder is reconfigured
there to match the latest properties.

2c4fde0eae vaapiencode: don't crash on NULL encoder on _finish().
Don't try to destroy an encoder, in GstVideoEncoder::finish() handler,
if it was not created in the first place. Return "not-negotiated" error
since this means we did not even reach GstVideoEncoder::set_format(),
where the encoder could have been created.

This fixes a crash when the vaapiencode_* plug-in elements get deallocated
and that we failed to negotiate either pad.

449ac54348 vaapiencode: fix negotiation process of output caps.
The specified caps in gst_video_encoder_set_output_state() function
arguments should not contain any resolution, pixel-aspect-ratio,
framerate, codec-data et al. Those rather should be set through the
returned GstVideoCodecState. This means that output caps creation
could be delayed until before gst_video_encoder_finish_frame() is
called.

This greatly simplifies the GstVideoEncoder::set_format() callback
by the way.

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.
