Instead of recalculating the miscellaneous buffer parameters for
every buffer, it is only done once, when the encoder is configured.
And for every buffer, the same structures are just copied.

This is patch pretends to decouple the assignation of the values
in the parameter structures and the VA buffer's parameters setting.
It may lead to some issues since HRD, framerate or controlrate may
not be handled by the specific encoder, but they are set in
the VA buffer's parameters.
I leave as it because this patch is just a transitional patch.
https://bugzilla.gnome.org/show_bug.cgi?id=783449
According to the VA documentation:
The framerate is specified as a number of frames per second,
as a fraction. The denominator of the fraction is given in
the top half (the high two bytes) of the framerate field, and
the numerator is given in the bottom half (the low two bytes).
For example, if framerate is set to (100 << 16 | 750), this is
750 / 100, hence 7.5fps.
If the denominator is zero (the high two bytes are both zero)
then it takes the value one instead, so the framerate is just
the integer in the low 2 bytes.
This patch fixes the the framerate calculation in vp8 encoder
according to this.

Move frame-rate parameter from ensure_misc_params() to
ensure_contro_rate_param() since it only has meaning when the
control rate is either VBR or CBR.

Move the Hypothetical Reference Decoder (HRD) parameter, from
ensure_misc_params() to ensure_control_rate_params(), since it
only shall be defined when the control rate is either VBR or CBR.
https://bugzilla.gnome.org/show_bug.cgi?id=783449
Instead of filling the control rate param in ensure_misc_params(),
this patch refactor it out, as a first step to merge the same code
for all the encoders.

Instead of using a proxy to story the buffer quality level, the
encoder now uses the native VA structure, which is copied to the
dynamically allocated VAEncMiscParameterBuffer.
This approach is computationally less expensive.
Right now, H264 and HEVC can set as a property the number of slices to
process. But each driver can set a maximum number of slices, depending
on the supported profile & entry point.
This patch verifies the current num_slices to process against the maximum
permitted by the driver and the media size.

- Use gst_element_send_event() instead of gst_pad_push_event()
- don't zero App structure
- check for pipeline parsing error
- only get vaapisink for property set
When state of vaapisink is changed from PLAYING to NULL, the handle_events
flag is set to FALSE, and never recovered, and then event thread is never
going to run.
So we should allow to set the flag only when users try it.

Since we started using VPP in VaapiWindowX11, we need to care about
the case that src rect and window's size are different.
So, once VPP has converted to other format, we should honor the
size of the VPP's surface as source rect. Otherwise, it is cropped
according the previous size of the source rect.

Queries if the driver supports "Region of Interest" (ROI) during the config
creation.
This attribute conveys whether the driver supports region-of-interest (ROI)
encoding, based on user provided ROI rectangles. The attribute value is
partitioned into fields as defined in the VAConfigAttribValEncROI union.
If ROI encoding is supported, the ROI information is passed to the driver
using VAEncMiscParameterTypeROI.

This patch adds the handling of VAEncMiscParameterTypeQualityLevel,
in gstreamer-vaapi encoders:
The encoding quality could be set through this structure, if the
implementation supports multiple quality levels. The quality level set
through this structure is persistent over the entire coded sequence, or
until a new structure is being sent. The quality level range can be queried
through the VAConfigAttribEncQualityRange attribute. A lower value means
higher quality, and a value of 1 represents the highest quality. The quality
level setting is used as a trade-off between quality and speed/power
consumption, with higher quality corresponds to lower speed and higher power
consumption.
The quality level is set by the element's parameter "quality-level" with a
hard-coded range of 1 to 8.
Later, when the encoder is configured in run time, just before start
processing, the quality level is scaled to the codec range. If
VAConfigAttribEncQualityRange is not available in the used VA backend, then
the quality level is set to zero, which means "disabled".
All the available codecs now process this parameter if it is available.

When downstream negotiates a pixel-aspect-ratio of 0/1, the
calculations for resizing and formatting in vaapipostproc and
vaapisink, respectively, failed, and thus the pipeline.
This patch handles this situation by converting p-a-r of 0/1 to
1/1. This is how other sinks, such as glimagesink, work.

Since it's created by itself, it should be unref-counted
after gst_buffer_pool_config_set_allocator call. Afterwards,
this allocator will be ref-counted again when assigning to priv->allocator.
https://bugzilla.gnome.org/show_bug.cgi?id=781577
Sometimes a video decoder could set different buffer pool
configurations, because their frame size changes. In this case we
did not reconfigure the allocator.
This patch enables this use case, creating a new allocator inside
the VAAPI buffer pool if the caps changed, if it is not dmabuf-based.
If so, it is just reconfigured, since it doesn't have a surface pool.

Sometimes gst_vaapi_window_wayland_sync returns FALSE when poll returns EBUSY
during destruction.
In this case, if GstVaapiWindow is using vpp, leak of vpp surface happens.
This surface is not attached to anything at this moment, so we should release
it manually.

When the frame listener callbacks 'done', the number of pending
frames are decreased. Nonetheless, there might be occasions where
the buffer listener callbacks 'release', without calling previously
frame's 'done'. This leads to problem with
gst_vaapi_window_wayland_sync() operation.
This patch marks as done those frames which were callbacked, but if
the buffer callbacks 'release' and associated frame is not marked
as 'done' it is so, thus the number of pending frames keeps correct.

Don't call gst_vaapi_window_wayland_sync() when destroying the
wayland window instance, since it might lead to a lock at
gst_poll_wait() when more than one instances of vaapisink are
rendering in the same pipeline, this is because they share the
same window.
Since now all the frames are freed we don't need to freed the
private last_frame, since its address is invalid now.

Fix leakage of the last wl buffer.
VAAPI wayland sink needs to send a null buffer while destruction,
it assures that all the wl buffers are released. Otherwise, the last
buffer's callback might be not called, which leads to leak of
GstVaapiDisplay.
This was inspired by gstwaylandsink.

The proxy object of wl_buffer for the last frame remains in the
wl_map. Even though we call wl_buffer_destroy() in
frame_release_callback(), the proxy object remains without being
removed, since proxy object is deleted when wayland server sees the
delete request and sends 'delete_id' event.
We need to call roundtrip before destroying event_queue so that the
proxy object is removed. Otherwise, it would be mess up as receiving
'delete_id' event from previous play, when playing in the next
va/wayland window with the same wl_display connection.

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.
