This patch enables the Constant BitRate encoding mode in VP8 encoder.
Basically it adds the configuration parameters required by libva to
CBR enconding.

When dmabuf is negotiated downstream and decoding and rendering are
not done on the same device, the layout has to be linear in order for
the memory to be shared accross devices, since each device has its
own way to do tiling.
Right now this code is rather just a to-do comment, since we are not
fetching the device ids.

Reduce frame num gaps so that we don't have to create unnecessary
dummy pictures, just throw them away.

Use new -base API gst_video_decoder_allocate_output_frame_full() to
pass the current proxy/surface to the pool.
The pool will will export thins given surface instead of exporting a
brand new surface that will never be filled in with meaningfull data.
https://bugzilla.gnome.org/show_bug.cgi?id=755072
Overriding the vmethod acquire_buffer() it is possible to attach the
right GstMemory to the current acquired buffer.
As a matter of fact, this acquired buffer may contain any instantiated
GstFdmemory, since this buffer have been popped out from the buffer
pool, which is a FIFO queue. So there is no garantee that this buffer
matches with the current processed surface. Evenmore, the VA driver
might not use a FIFO queue. Therefore, it is no way to guess on the
ordering.
In short, acquire_buffer on the VA driver and on the buffer pool return
none matching data, we have to manually attach the right GstFdMemory to
the acquired GstBuffer. The right GstMemory is the one associated with
the current surface.

gst_vaapi_dmabuf_memory_new() always exports a surface. Previously, it
had to create that surface. Now it can also export an already provided
surface. It is useful to export decoder's surfaces (from VA context).
https://bugzilla.gnome.org/show_bug.cgi?id=755072
This patch adds a GstMemory as a variable member of the buffer proxy,
because we will need to associate the buffer proxy with the memory
which exposes it. Later, we will know which memory, in the video buffer
pool, is attached to the processed surface.

Do not add the meta:GstVideoGLTextureUploadMeta feature if the render
element can handle dmabuf-based buffers, avoiding its negotiation.
Similar as "vaapidecode: do not add meta:GstVideoGLTextureUploadMeta
feature if can dmabuf"

If the negotiated caps are raw caps and downstream supports the
EGL_EXT_image_dma_buf_import extension, then the created allocator
is the DMAbuf, configured to downstream.
At this moment, the only element which can push dmabuf-based buffers
to downstream, is vaapipostproc.
In order to enable, in the future, dmabuf-based buffers, the vaapi base
plugin needs to check if downstream can import dmabuf buffers.
This patch checks if downstream can handle dmabuf, by introspecting the
shared GL context. If the GL context is EGL/GLES2 and have the extension
EGL_EXT_image_dma_buf_import, then dmabuf can be negotiated.

The surface created for downstream is going to be filled by VAAPI
elements. So, the driver needs write access on that surface.
This patch releases the derived image held by the proxy, thus the
surface is unmarked as busy.
This is how it has to be done as discussed on libva mailing list.

Add GstPadDirection param to gst_vaapi_dmabuf_allocator_new(), thus
we later could do different thing when the allocated memory is for
upstream or dowstream, as required by VA-API.

Thus, when generating the allowed caps, the element will throw a
warning and it will use its caps template.
This behavior might be a bug in the VA driver.
https://bugzilla.gnome.org/show_bug.cgi?id=775490
A value of width/height property should be set to out caps,
if negotiation had been going properly.
So we can use srcpad_info when making decision of scaling.

If a GstVaapiDisplay is not found in the GStreamer context sharing,
then VAAPI elements look for a local GstGLContext in gst context
sharing mechanism ('gst.gl.local.context').
If this GstGLContext not found either then, only the VAAPI decoders
and the VAAPI post-processor, will try to instantiate a new
GstGLContext.
If a valid GstGLContext is received, then a new GstVaapiDisplay will
be instantiated with the platform, API and windowing specified by the
instantiated GstGLContext.

Instead of calling g_return_val_if_fail() to check the context type, we
should use a normal conditional, since it is possible that other context types
can arrive and try to be assigned. Otherwise a critical log message is
printed.
This happens when we use playbin3 with vaapipostproc as video-filter.
https://bugzilla.gnome.org/show_bug.cgi?id=777409
Every time a new buffer is allocated, the pool is activated. This
doesn't impact in performance since gst_buffer_pool_set_active()
checks the current state of the pool. Nonetheless it logs out a
message if the state is the same, and it floods the logging subsystem
if it is enabled.
To avoid this log flooding first the pool state is checked before
changing it.
When a new sink caps arrive the internal decoder state is updated
and, if it is, request a downstream renegotiation.
Previously, when new caps arrived the whole decoder where destroyed
and recreated. Now, if the caps are compatible or has the same codec,
the internal decoder is kept, but a downstream renegotiation is
requested.

Redirect libva's logs to GStreamer logging mechanism. This is
particularly useful when VA is initialized, because it always logs
out the drivers details.
In order to achieve this a new helper function was added as a wrapper
for the vaInitialize() function.

Adds two buffers as the default value of minimum buffer.
This would be used when creating and proposing vaapi bufferpool for
sink pad, hence the upstream element will keep, at least, these two
buffers.

If the frame is a cloned picture, its PTS comes from its parent
picture. In addition, the base decoder doesn't set a valid PTS to
the frame corresponding to the cloned picture.

Rename the parameters 'vip' and 'flags' to 'alloc_info' and
'surface_alloc_flags' respectively. The purpose of this change is
to auto-document those parameters.
Also, aligned to this patch, the local 'alloc_info' variable was
renamed as 'surface_info', because it stores the possible surface's
video info, not the allocate one.
In order to auto-document the code, this patch renames the 'vip'
parameter in the functions related to gst_vaapi_video_allocator_new ()
to 'alloc_info', since it declares the allocation video info from
the vaapi buffer pool.
gst_vaapi_surface_new_with_format() is a wrapper for
gst_vaapi_surface_new_full (). In this case, the former is simpler
than the first. This patch changes that.
If src pad caps have changed, it needs to notify it downstream. In
addition, do not set passthrough if they have changed.
Otherwise, transform sometimes starts processing before caps change.
The passthrough value will be set in fixate later in this case.
https://bugzilla.gnome.org/show_bug.cgi?id=775204
Add a capsfilter forcing the caps
"video/x-raw(memory:VASurface), format=(string)NV12" between the
queue and the vaapipostproc so no renegotiation is required.
