support multiple monitors on a single display channel

Browse Source 
Adds on device:

RAM
 Header
  monitors_config - pointer

 QXLMonitorsConfig
  count == n
  max_allowed = N >= 0
  QXLHead 1
  ...
  QXLHead n
   id, surface_id, x, y, width, height, flags

IO:
 QXL_IO_MONITORS_CONFIG
  server flushes command ring, then calls server callback for changing monitors config.

New revision to let the driver know about the new io:
 QXL_REVISION_STABLE_V12=0x04,

Adds server/client capability:
 SPICE_DISPLAY_CAP_MONITORS_CONFIG

Server message will be added in spice-server and spice-common.

Version is bumped to 0.12.0 to indicate new IO and structs
