Log Message:
- added video_vosf_init()/video_vosf_exit() for initialization and destruction
  of the internal structures used for the VOSF system
- use vm_acquire()/vm_release() for VOSF buffers and hope the_buffer is
  allocated above RAM address space (temporary workaround for 64-bit
  addressing systems)
- don't free() screen buffers in driver_base dtor
- don't free() memory mapped buffers in driver_base dtor
