faf4390c38 Save the "bustype" from our attach args in the controller "softc" 
and use that instead of hard-coding BUS_VME32 everywhere.
(The Sun3X needs a more specific bustype value.)

1ea958fad8 Move initialization code from xxattach to xx_init and call that 
from both xxattach and xxopen instead of calling xxattach from
xxopen with faked up autoconfig args.  Fix warnings.

5b39541e48 New generic disk framework. Highlights: 
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

b3a6cbaeb0 New from Chuck Cranor: drivers for SMD disks! 
xd: Xylogics 753/7053 SMD disk controller

These now compile, but have not been tested.
