First fix a memory leak when skipping cursor planes by inverting the
check and putting everything, but the free, in the body.
Then fix a missed drmModeFreePlane by simply copying the fields of the
drmModePlane we are interested in and freeing the drmModePlane struct
early.

We are currently using primary / overlay planes drm objects, assuming that primary plane is osd and overlay plane is video.
This commit is doing two things :
- replace the primary / overlay planes members with osd and video planes member without the assumption
- Add two more options to determine which one of the primary / overlay is associated to osd / video.
- It will default osd to overlay and video to primary if unspecified

This patch adds
- DRM connector object to atomic context.
- fd property to the drm atomic object as well as a method to read blob type properties.
This allows to ensure that the proper connector is picked up, especially when specifying it
from the commandline, and also allows to make sure we're using the right one when embedding
with interop into an application.

Passing in an invalid DRM overlay id with the --drm-overlay option would
cause drmplane to be freed twice: once in the for-loop and once at the
error-handler label fail.
Solve by setting drmpanel to NULL after freeing it.
Also the 'return false' statement after the error handler label should
probably be 'return NULL', given that the return type of
drm_atomic_create_context returns a pointer.

This commit allows to use the AV_PIX_FMT_DRM_PRIME newly introduced
format in ffmpeg that allows decoders to provide an AVDRMFrameDescriptor
struct.
That struct holds dmabuf fds and information allowing zerocopy rendering
using KMS / DRM Atomic.
This has been tested on RockChip ROCK64 device.
