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.

a2ce90f34c change definition of profil() to make it 64-bit friendly. This has 
no practical consequence on 32-bit systems.  old prototype was
int profil(char *, int, int, int), and new one is int profile(char *,
size_t, u_long, u_int).  the size_t is the size of the buffer,
and the u_long is the 'starting offset'.  (I changed the last int
to u_int, because it's treated as a u_int everywhere, and isn't
logically a signed value.)

f5bbdfba41 bdwrite() should upgrade writes to tape devices by sending them to 
bawrite().  it's logically more correct (doesn't return an error code,
because it's async; bdwrite is also async), it still writes things
in-order, it makes sure the proper accountins is done (see the
wasdelayed cases in bwrite()), and it allows writes to vnodes on volumes
mountd with the MNT_ASYNC to be converted into delayed writes the way
God, err, Kirk intended.  Convert synchronous bwrite()s on MNT_ASYNC
file systems to delayed writes.
