        sys/dev/ccd.c: revision 1.133 via patch
        sys/dev/ccdvar.h: revision 1.31
Fix problems with ccd:
- Pending async I/O was tossed on unconfigure (should not happen, but..)
- It could exhaust memory under heavy I/O load.
- If memory allocation failed, disk transfers could stall.
- v_numoutput was updated without v_interlock held.
Additionally:
- Make it MPSAFE.
- Use kmem_alloc().
