Add features required for basic userland management utility:

 - implement user-initiated background drive rebuild
 - implement user-initiated background consistency check
 - log controller-initiated background rebuild/check operations

Try to fix the elusive "invalid log operation" bug, and panic if we do
hit this one in the hopes of getting better information.

Tidy up diagnostic messages.

Try to use disk_create/disk_destroy correctly.  This isn't working
properly yet, but it's not clear whose fault that is.
