Removed Files:
	src/sys/arch/xen/x86 [netbsd-3]: bus_dma.c

Log Message:
Pull up file removal (requested by yamt in ticket #175):
tweak x86 bus_dma code so that it can be used by xen port.
- distinguish paddr_t and bus_addr_t.
  for xen, use bus_addr_t in the sense of machine address.
- move _X86_BUS_DMA_PRIVATE part of bus.h into bus_private.h.
- remove special handling of xen_shm.  we can always grab
  machine address from pte.
