Tim Chase 1b8951b319 Prevent arc_c collapse
Adjusting arc_c directly is racy because it can happen in the context
of multiple threads.  It should always be >= 2 * maxblocksize.  Set it
to a known valid value rather than adjusting it directly.

In addition refactor arc_shrink() to a simpler structure, protect against
underflow in the calculation of the new arc_c value.
