[RFC v2] libdrm part of the render-node patch series

[Ilija Hadzic]

The following two patches are the rework of the patch series sent two weeks
ago [1] that add libdrm support for render node manipulation. All notes
described in [1] apply. A new option to render_node_add utility has
been added to specify the number of planes and plane IDs are supposed to
be the last in the ID list.

Regards,
