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.

no practical consequence on 32-bit systems. old prototype was
int profil(char *, int, int, int), and new one is int profile(char *,

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.)
