This mechanism comes from ffmpeg vaapi implementation, where they have
their own quirks.
A specific driver is identified by a substring present in the vendor
string. If that substring is found, a set of bitwise flags are store.
These flags can be accessed through the function
gst_vaapi_display_has_driver_quirks().
The purpose for this first quirks is to disable the put image try for
AMD Gallium driver (see [1]).

Don't reset the can_dmabuf field. This restores the
close/reset logic that existed prior to commit
ca2942176b in regards to
dmabuf support.
Plugins only call gst_vaapi_plugin_base_set_srcpad_can_dmabuf
once during startup, but may need to reset the other private
fields multiple times during negotiation. Thus, can_dmabuf
should be exempt from the resets.

GstVaapiMiniObject and GstVaapiObject are deprecated.
This is the first step to remove them by porting GstVaapiSurface as
a GstMiniBuffer descendant.

The base plugin public API function implementations determine
which pad should be passed to the internal helper functions.
Currently, only the base plugin static sinkpad and static
srcpad are supported/used. However, this change enables future
API functions to be added that can accept a pad (i.e. request pad)
from an element subclass (e.g. a GstVideoAggregator subclass).
Define a struct (GstVaapiPadPrivate) to encapsulate the
pad-specific data (i.e. buffer pool, allocator, info,
caps, etc.).
Add an interface to retrieve the data struct for a given
pad.
Finally, update the base plugin to use the data struct
throughout the implementation.
This will enable us to easily extend the base plugin in the
future to allow for N-to-1 pad subclasses (e.g. overlay/
composite).
If the allocation caps and negotiated caps are the same,
then ensure any previously negotiated video info is also
removed. This can occur when multi-resolution video
decoding returns to it's original resolution.
Fixes#170
The gst_vaapi_plugin_base_get_allowed_raw_caps is used for both sink
pad and src pad, which cause some bugs. For sink pad, we need to verify
vaPutImage() while for the src pad we need to verify vaGetImage().
For vaapidecoderXXX kind of plugins, the case is more complex. We need
to verify whether the decoded result(in some surface, NV12 format most
of the time) can be vaGetImage to some raw image format. Add more check
to fix all these problems.

The extract_allowed_surface_formats function just check whether
we can support some kind of surface/image format pair. We just
need to create a surface, create an image with the same video-format
and putImage from image to surface. All these operations success,
that kind of video-format is supported.
The old manner do not work for some kind of video-format. For example,
the RGBA kind of format will create a NV12 surface and RGBA image,
and the putImage will fail because the format is not same. And so
the RGBA format is not supported but actually it is supported.
Instead of using our own context handling for looking for GstGL
parameters (display, context and other context), this patch changes
the logic to use the utility function offered by GstGL.

The parameters of gst_gl_ensure_element_data() have to be not
local variable since they are going to be used to see if they're
set in gst_element_set_context() inside the API.
This is basically a revert of commit 3d56306chttps://bugzilla.gnome.org/show_bug.cgi?id=793643
When importing buffers to a VA-base buffer, it is required to copy
the metas in the original buffer, otherwise information will be
lost, such as GstVideoRegionOfInterestMeta.
https://bugzilla.gnome.org/show_bug.cgi?id=768248
This patch add the member copy_output_frame and set it TRUE when
when downstream didn't request GstVideoMeta API, the caps are raw
and the internal allocator is the VA-API one.

In propose_allocation() if the numer of allocation params is zero, the
system's allocator is added first, and lastly the native VA-API
allocator.
In decide_allocation(), the allocations params in query are travered,
looking for a native VA-API allocator. If it is found, it is reused as
src pad allocator. Otherwise, a new allocator is instantiated and
appended in the query.

gst.vaapi.app.Display context is made for applications that will
provide the VA display and the native display to used by the
pipeline, when are using vaapisink as overlay. There are no use
case for encoders, decoders, neither for the postprocessor.
In the case of the vaapisink, it shall query for gst.vaapi.Display
upstream first, and then, if there is no reply,
gst.vaapi.app.Display context will be posted in the bus for the
application. If the application replies, a GstVaapiDisplay object
is instantiated given the context info, otherwise a
GstVaapiDisplay is created with the normal algorithm to guess the
graphics platform. Either way, the instantiated GstVaapiDisplay
is propagated among the pipeline and the have-message bus message.
Also only vaapisink will process the gst.vaapi.app.Display, if
and only if, it doesn't have a display already set. This is
caused because if vaapisink is in a bin (playsink, for example)
the need-context is posted twice, leading to an error state.

As buffers negotiated with memory:VASurface caps feature can also be
mapped, they can also be configured to use VA derived images, in other
words "direct rendering".
Also, because of the changes in dmabuf allocator as default allocator,
the code for configuring the direct rendering was not clear.
This patch cleans up the code and enables direct rendering when the
environment variable GST_VAAPI_ENABLE_DIRECT_RENDERING is defined,
even then the memory:VASurface cap feature is negotiated.

Set if source pad can handle dmabuf only if the GstGL context comes
from downstream.
It is possible to know that at two moments:
1\ In the case of GstGLTextureUpload caps feature is negotiated and
downstream pool reports back gst.gl.GstGLContext.
2\ When GstGLContext is found as GstContext from dowstream.

This patch refactors the code by adding the function
vaapi_plugin_base_set_srcpad_can_dmabuf(), it determines if the passed
GstGLContext can handle dmabuf-based buffers.
The function is exposed publicly since it is intended to be used later
at GstVaapiDisplay instantiation.

Refactor gst_vaapi_plugin_base_create_gl_context() in order to check
the return value of gst_gl_ensure_element_data(). The result is a code
bit cleaner.
There is a regression in 7a206923, since the buffer pool ditches all
the buffers generated by them because the pool config size is
different of the buffer's size.
Test pipeline:
gst-launch-1.0 filesrc location=big_buck_bunny_1080p_h264.mov \
! qtdemux ! vaapih264dec ! vaapipostproc ! xvimagesink \
--gst-debug=GST_PERFORMANCE:5
The allocator may update the buffer size according to the VA surface
properties. In order to do this, the video info is modified when the
allocator is created, which reports through the allocation info the
updated size, and set it to the pool config.
The vaapi video decoders might have different allocation caps from
the negotiation caps, thus the GstVideoMeta shall use the negotiation
caps, not the allocation caps.
This was done before reusing gst_allocator_get_vaapi_video_info(),
storing there the negotiation caps if they differ from the allocation
ones, but this strategy felt short when the allocator had to be reset
in the vaapi buffer pool, since we need both.
This patch adds gst_allocator_set_vaapi_negotiated_video_info() and
gst_allocator_get_vaapi_negotiated_video_info() to store the
negotiated video info in the allocator, and distinguish it from
the allocation video info.

Direct rendering (use vaDeriveImage rather than vaPutImage) has better
performance in some Intel platforms (Haswell, for example) but in others
(Skylake) is the opposite.
In order to have some control, the patch enables the direct rendering
through the environment variable GST_VAAPI_ENABLE_DIRECT_RENDERING.
Also it seems to generating some problems with gallium/radeon backend.
See bug #779642.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=755072
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.

Add GstPadDirection param to gst_vaapi_dmabuf_allocator_new(), thus
we later could do different thing when the allocated memory is for

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.

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.
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.

First, deactivate source pad pool when the out caps change, and if so,
destroy texture map, the source pad allocator and pool only if the
new caps are different from the ones already set.
