randr: Add Monitor support (v1.1)
Store the user-defined monitors in the RandR screen private. Generate a list of monitors from both the user-defined ones and from any outputs not mentioned in one of the user-defined monitors. This list covers both the outputs in the main screen as well as any slaves. v1.1: airlied: fix up primary skipping bug, fix wrong height initialiser add get_active flag from updated protocol.
