Rework DRI buffer mappings and sarea setup to allow for moving buffers.

While this has been a desired feature for some time, to allow for reallocation
of the front buffer, it was made more necessary by the desire to avoid
requiring a NO_MOVE buffer type in TTM because buffer objects may not be left
pinned over VT switch.  This is a step towards making those buffers
movable and resizable.
