Modified Files:
	syssrc/sys/dev/ic: ac97.c ac97var.h

Log Message:
Shadow the AC'97 codec registers.  This adds two capabilities:
* support devices that crash when reading the codec registers; a flags
  interface is added to the host interface and one flag is defined
  (AC97_HOST_DONT_READ).
* new API (restore_ports) for restoring the user's settings.  This
  can be useful after an APM resume after a suspend to disk.
