2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

3cd14f7597 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

8a6ad45eed In fdcretry(), if we're not using implied seeks, set the state to DOSEEK
rather than SEEKCOMPLETE before retrying the operation.  If implied seeks
are being used, the state is set to DOIO (no change).  This is why I
couldn't reproduce the disk_unbusy() panic on my SS2; it uses implied
seeks.  Patch from John F. Woods <jfw@jfwhome.funhouse.com>

8a5504241e Three distinct changes:
- Better disklabel handling.  While a disklabel isn't used
	  in the driver, some versions of the OpenPROM insist on
	  one being present in order to boot from floppy.  These
	  changes provide a default label (in a way similar to how
	  the SCSI disk driver provides a default) so that a user
	  can more easily place the label on the disk.

	- Fix semi-bug in bootpath handling.  It appears as if the
	  bootpath can appear in a couple of formats: "/fd@0,0", which
	  is what bootpath_fake() creates on v0 proms and may be
	  passed by some v2 proms, and "/fd0" which is what the
	  v2 prom on my SS2 passes.  We now handle both formats.

	- Use a mountroot hook to eject the floppy and wait for
	  the user to insert a filesystem floppy if we're the boot/root
	  device.

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.
