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.

When unconfiguring a ccd, only free as many interleave indices as

Fix bad pointer deref, memory leak, and geometry calculation, pointed

out by Jochen Pohl in PR #1588 . Change the interleave index to an
array of ints rather than an array of chars to avoid losing in the event
one has more than 127 components.

Add the partition offset to the block number in ccdstart() as opposed

to ccdstrategy(), and do it in a way that doesn't corrupt the block number
for residuals. (What was I _thinking_?!)

Implement a simple locking mechanism and use it, for sanity's sake.
...
In ccdopen(), don't update the disklabel if any partition is already open.
Prevents race bewteen ccdstrategy() and ccdgetdisklabel().
