Since there is duplicated code in h264/265 encoder, we could
refactor it to avoid duplicated code.

From man open(2):
The O_CLOEXEC, O_DIRECTORY, and O_NOFOLLOW flags are not specified
in POSIX.1-2001, but are specified in POSIX.1-2008. Since glibc
2.12, one can obtain their definitions by defining either
_POSIX_C_SOURCE with a value greater than or equal to 200809L or
_XOPEN_SOURCE with a value greater than or equal to 700. In glibc
2.11 and earlier, one obtains the definitions by defining
_GNU_SOURCE.
And indeed, with the uClibc C library, O_CLOEXEC is not exposed if
_GNU_SOURCE is not defined. Therefore, this commit fixes the build of
gstreamer-vaapi with the uClibc C library.

The "Reporting bugs" section gives
https://bugzilla.gnome.org/enter_bug.cgi?product=gstreamer-vaapi as the
link to report a bug, but this link says "Sorry, entering a bug into the
product gstreamer-vaapi has been disabled.".
This commit fixes the URL to point to the proper location, and also
removes the following paragraph that is no longer correct.

Particularly in GNOME Wayland, the negotiated or created GL context
defines a GLX environment, but VAAPI fails to create a GLX VA
display because there is no a DRI2 connection.
This patch retries to create the VA display if VA cannot create one
with the GL context parameters. Now using the old list of display
types.
This should also work in the case of systems with two GPU, when the
non-VAAPI has the graphics environment, and the VAAPI-enabled one
shall work headless.

The AC_CHECK_HEADERS macro was failing to locate some headers, in
particular the va_enc_* headers due to missing compiler flags.

Currently, it set rate control information even when query fails.
In addition, it doesn't update any more since the flag
got_rate_control_mask is set to TRUE.

The encoder should be able to change its caps even it is already
processing a stream.
This is suppose to happen after a flush so the codedbuf_queue should
be empty.

Configuring GCC to verify possible usage of uninitialized variables,
shows that found_index might be used without previous assignation.
This patch assigns a initial value to found_index, also avoid a
branching when returning the result value.

Rename to be consistent with H.264 and also H.265 encoder. The
meson build assumed this was already consistently named, and so
previously was not able to actually build the H.265 decoder.

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

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.

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