If we drop many frames at once, printing one message per video frame and
one per audio packet would cause a lot of disk IO. Just print a total at
the end.

Now that we are doing lazy allocation, we may endup calling _stop()
before the allocator was created. As a side effect, we need to nul-check
the pointer before calling it's method (_clear_cache()).

DRM_RDWR was not defined until libdrm 2.4.68. However,
in configure.ac we only require libdrm >= 2.4.55.
Seems silly to to bump minimum libdrm version for a simple
define. Thus, define DRM_RDWR if it's not defined.
This fixes compilation error introduced in:

kms: Export DMABuf from Dumb buffer when possible
https://bugzilla.gnome.org/show_bug.cgi?id=787593
Signed-off-by: U. Artie Eoff <ullysses.a.eoff@intel.com>
When we guess the strides, we need to also update the GstVideoInfo.size
otherwise the memory size will be set to something smaller then needed.
This was causing crash with the DMABuf exportation, since we would not
mmap() a large enough buffer.
https://bugzilla.gnome.org/show_bug.cgi?id=787593
The buffer itself is 128 bytes into the allocated memory area, to be
able to store the size and other metadata before it. Freeing the buffer
directly will make malloc moderately unhappy.
If bo allocation failed we destroy the buffer and return GST_FLOW_ERROR,
but the @buffer pointer was still pointing to the address of the
destroyed buffer. gst_kms_sink_copy_to_dumb_buffer() was then trying to
unref it when bailing out causing a crash.
Leave @buffer untouched if allocation failed to fix the crash.
Also remove the check on *buffer being not NULL as gst_buffer_new()
will abort if it failed.

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.
