8574154cc8 kmssink: Avoid drain on caps changes
Draining systematically on caps changes was a hack. Instead, properly
save the render information used to render last_render, and use that
information to drain. This fixes performance issues met with video crop
meta and per frame caps changes.

7d79378895 kmssink: Add "restore-crtc" property
This adds "restore-crtc" property using which one
can restore previous crtc mode.

By default it is enabled, if CRTC was already
active with a valid mode and kmssink set a new mode
on CRTC using force-modesetting.

This helps user restore previous crtc mode and get
the previous session back after running a kmssink
pipeline involving a force-modesetting.

For e.g. When running a kmssink pipeline on rpi
using force-modesetting on tty console, it was giving
a blank screen after pipeline, and now with help of restore-crtc
functionality, CRTC is set with previous crtc mode
previously active on tty console.

63dca26fac kmssink: Add 'plane-properties' property
This is similar to 'connector-properties' but will change
selected plane properties instead.

71ab97cba6 kmssink: add 'connector-properties' prop
Can be used to pass custom connector properties to DRM. Properties can
be enumerated using modetest tool. These properties can then be applied
with the following gst-launch-1.0 syntax. Note that the name of the
structure is ignored.

  ... ! kmssink connector-properties="s,props1=value,props2=value"

b24bb73101 kmssink: support videooverlay interface
Implement videooverlay interface in kmssink, divided into two cases:
when driver supports scale, then we do refresh in show_frame(); if
not, send a reconfigure event to upstream and re-negotiate, using the
new size.

9d5a524547 kmssink: Move the mem cache into the allocator
No functional change, the cache will be later reused by the buffer
pool to keep track of the kmssink memory when exporting dmabuf.

1ec081f96d Revert "kmssink: support videooverlay interface"
This is causing hard failure for non-squared pixel. The fix isn't
trivial so taking offline by reverting.

This reverts commit db07f4507d.

0a0bc8ab94 kmssink: Track cached kmsmem and clear them on drain
In this patch we keep track of the cached kmsmem in a way
that we can clear the cache during the drain process. This
release the framebuffer before waiting for the next vblank,
hence add support for DRM driver (like Intel one) that release
the associated DMABuf reference asynchronously.

9ed9c14eb5 kmssink: if the plane can not scale, retry without scaling and remember
Retry the drmModeSetPlane call without scaling if the first try fails,
and remember not to scale anymore.

649364b923 kmssink: configure display mode during set_caps
Configure the display mode when setting the negotiated caps instead of
during showing the first frame.

A framebuffer is required to set the mode. Allocate a buffer object
according to the negotiated caps and use it to set the mode. This buffer
object cannot be freed until another page flip happened on the crtc
(i.e., until the first frame is rendered).

f52baadd1e kmssink: add mode setting and base plane rendering
The kmssink assumed that the mode was already set by another application
and used an overlay plane for displaying the frames.

Use the preferred mode of the monitor and render to the base plane if
the crtc does not have a valid mode.

b2c58d3bc5 kmssink: add sync support for secondary pipes
The vblank event request must specify the crtc for which to request
the event. This fixes kmssink synchronisation for crtcs other than
the first.

b29f7d048c kmssink: wait for page flip or vblank
This patch requests for drmModePageFlip() for the used CRTC, if the kernel
module suppports async page flip. If it does not, the element requests for a
vblank event. A GstPoll waits for the event to happen.

c419d17dbf kmssink: add dmabuf support
This patch will enable the import of dmabufs into a KMS buffer using
the PRIME kernel interface.

If the driver does not support prime import, the method is skipped.

It has been tested with a Freescale I.MX6 board.

620e1d2fcd kmssink: add plugin and sink element
This is simple video sink that use libdrm/libkms API to render frames.

The element uses planes to render through drmModeSetPlane().

It has been tested in an Exynos4412 board and in a Freescale I.MX6 board.
