When unconfiguring a ccd, only free as many interleave indices as
...
were allocated, which may not be the same as the number of components

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().
