    Detail:
      hdr/HALEntries - Add new HAL_Video_StartupMode HAL entry to allow the HAL to specify a startup mode
      s/HAL, s/Kernel - Tweaked debug routines
      s/vdu/vdudriver - Make use of HAL_Video_StartupMode in InitialiseMode to decide what initial mode should be. Clean up some hacks & debug. Improve handling of external framestores; if bit 5 of GraphicsV_DisplayFeatures r0 is set, the kernel will now allow the display driver to grow/shrink/move its framestore in response to mode changes.
      s/vdu/vdugrafv - Adjust default GV_FramestoreAddress implementation to only claim vector if HAL returns a framestore
      s/vdu/vduswis - Re-enable FindOKMode
