thorpej 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.

thorpej 17eb6e2bc1 Move the old-style disk instrumentation "structures" to a central location
(sys/kern/subr_disk.c) and note that they should/will be deperecated.

perry 74e1e47aeb fixed my own pr 1758 -- the floppy drive motor was not being turned off
at halt time, especially if a floppy was mounted. Added a shutdown hook
to turn off the motor. Per a request by mycroft, the cookie from the hook
is saved in a new member I added to the fd_softc structure.

perry 765bb97fe9 fix my own pr 1762, in which it was noted that boot2 used a busy loop
to time out the boot prompt.  Now uses a usleep() routine that calls
the BIOS and the functionality is separate from gets(). Timeout is
#defined to 5 seconds. Also did some minor cleanup in preparation to
prototype/ANSIfy everything.
