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.

We used to to handle the driver pitch only for single plan video format.
Add support for multi planes format by re-using the extrapolate function
from the v4l2 element.
Also use this pitch to calculate the proper offsets.
Prevent DRM drivers to pick a slow path if the pitches/offsets don't
match the ones it reported.

No semantic change, just renamed the 'tmp' variable to a more meaningful
name and to use the same structure as in gst_kms_allocator_bo_alloc().
Needed as I'm going to move the gst_memory_init() call after the
allocation of the DUMB buffer.

HRESULT is unsigned long on Windows, but the Decklink headers define
it to 'int' on Linux. Confusingly, the defines that talk about the
possible return values for it use long constants. The easy fix would
be to change the linux/LinuxCOM.h header, but that's copied from the
decklink SDK.
Change the logging to always upcast to unsigned long while printing
HRESULT for consistency across platforms.

The default memory allocator of the decklink library allocates
a fixed pool of buffers, and the number of buffers is unknown.
This makes it impossible do useful queuing downstream. The new
memory allocator can create an unlimited number of buffers,
giving all queuing features one would expect from a live source.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=782774
kmssink keeps a reference on the last rendered buffer. If this buffer
refers to an upstream buffer, it should be should be released on DRAIN
and ALLOCATION queries so all upstream buffers can be returned to the
pool if needed. As the buffer may be used for scanout, we copy this
buffer into a dumb buffer prior to let it go.
Based on patch from Guillaume Desmottes <guillaume.desmottes@collabora.com>
https://bugzilla.gnome.org/show_bug.cgi?id=782774
This otherwise breaks DMABuf reclaiming. This is not visible from
userspace, but inside the kernel, the DRM driver will hold a ref to the
DMABuf object. With a V4L2 driver allocating those DMABuf, it then
prevent changing the resolution and re-allocation new buffers.

Milliseconds was wrong and made use of this timeout quite
confusing. The code uses the value as microsenconds so
any meaningful number was off by orders of magnitude.
Set the pts and dts on the frame that we receive from the msdk.
Also fix the inverted logic in setting sync points, previously we
were marking all frames as sync points except IDRs.

When extracting an aux buffer from an MJPG carrier, at
*least* put the original timestamp on it, even if we
fail to apply any other timestamp (which we always do
at the moment, because the timestamp calculating code
was never finished). Apply a DTS using the camera
supplied delay value as well, assuming that there's
no re-ordering going on (there isn't in the C920,
which is really the only extant camera doing this
stuff) and a warning if that turns out not to be true.
