When interacting with SW elements, the buffers and underlying video
memory could be mapped as read/write. However, we need to use those
buffers again as plain VA surfaces, we have to make sure the VA image
is thus committed back to VA surface memory.
This fixes pipelines involving avdec_* and vaapi{postproc,sink}.
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.

Simplify GstVaapiVideoMeta to only hold a surface proxy, which is
now allocated from a surface pool. This also means that the local
reference to the VA surface is also gone, as it could be extracted
from the associated surface proxy.
Drop the following functions that are not longer used:
- gst_vaapi_video_buffer_new_with_surface()
- gst_vaapi_video_meta_new_with_surface()
- gst_vaapi_video_meta_set_surface()
- gst_vaapi_video_meta_set_surface_from_pool()
Fix gst_vaapi_video_meta_new_from_pool() to allocate VA surface proxies
from surface pools instead of plain VA surfaces. This is to simplify
allocations now that surface proxies are created from a surface pool.
Add support for GstVideoCropMeta in GStreamer >= 1.0.x builds and gst-vaapi
specific meta information to hold video cropping details. Make the sink
support video cropping in X11 and GLX modes.
Some video clips may have a clipping region that needs to propogate to
the renderer. These helper functions make it possible to attach that
clipping region, as a GstVaapiRectangle, the the video meta associated
with the buffer.

Since GST_VAAPI_IS_xxx_VIDEO_POOL() was only testing for NULL and not
the underlying object type, the gst_vaapi_video_meta_new_from_pool()
was hereby totally broken. Fixed this regression by using the newly
provided gst_vaapi_video_pool_get_object_type() function.
Make it possible to copy GstVaapiVideoMeta objects, unless they contain VA
objects created from GstVaapiVideoPool. This is mostly useful to clone a
GstVaapiVideoMeta object containing a VA surface proxy so that to alter its
rendering flags.
Fix GstVaapiVideoMeta to allow VA objects to be destroyed when they are
reset to NULL. i.e. make gst_vaapi_video_meta_set_{image,surface}() and
gst_vaapi_video_meta_set_surface_proxy() actually clear VA objects when
argument is NULL.
Port vaapidecode and vaapisink plugins to GStreamer API >= 1.0. This
is rather minimalistic so that to test the basic functionality.
Disable vaapiupload, vaapidownload and vaapipostproc plugins. The latter
needs polishing wrt. to GStreamer 1.x functionality and the former are
totally phased out in favor of GstVaapiVideoMemory map/unmap facilities,
which are yet to be implemented.

Move GstVaapiVideoMeta from core libgstvaapi decoding library to the
actual plugin elements. That's only useful there. Also inline reference
counting code from GstVaapiMiniObject.
