gralloc: provide methods for hwc to change handle of a plane
Patch changes reserve_plane to get id number as additional parameter.
This can be used by hwc to make changes to a particular plane. New
api hwc_set_plane_handle is introduced so that hwc can change the
buffer handle of a plane, this is required because after plane has
been reserved for a particular ui layer, this handle can change as
the layer is typically multibuffered.
