e819063285 Define a full set of [234][bl]tol() and lto[234][bl]() conversion functions, 
inlined.
Use sized types in protocol structures.
Make the definition of scsi_sense_data less ugly.

532e997971 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.

8068d9eeb2 Handle cases like the following: 
- controller calls scsi_done() with error XS_TIMEOUT
	- scsi_done() calls sddone()
	- sddone() calls disk_unbusy()
	- scsi_done() calls controller to retry command (missing the
	  call to disk_busy())
	- controller calls scsi_done()
	- scsi_done() calls sddone()
	- sddone() calls disk_busy(), which panics because of the imbalance.
Bug noticed by Leo Weppleman, who also suggested this fix; pass an additional
boolean argument ("complete") to the device's "done" routine, with a
value of `0' passed from the previous call to "done", and add an additional
call to "done" when the xfer resources are freed.

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.

b6c6d46a82 In sdminphys(), add a comment about the semantics of the "length" field 
in a 6-byte read/write cdb (namely, length == 0 really means 256), and
that we handle this conservatively by limiting the transfer to 255 blocks.
*sigh* One just never knows how a pre-scsi-1 device is going to behave.

c9895db015 In both cd.c and sd.c: 
If the read or write request can fit into a 6-byte cdb, then
	use a 6-byte cdb, otherwise use the 10-byte as before.

In sd.c:
	In sdattach(), make a note if the device is "ancient" (i.e.
	inqbuf.version & SID_ANSII == 0).

	Implement sdminphys(): if the device is "ancient", shorten the
	transfer so it will fit into a 6-byte cdb.

These changes have eliminated the rejected read/write requests on my
Sun 3/60 with 2 ESDI disks behind an Emulex MD21.
