ucred system overhaul:
1) mpsafe (protect the refcount with a mutex).
2) reduce duplicated code by removing the inlined crdup() from crcopy()
   and make crcopy() call crdup().
3) use M_ZERO flag when allocating initial structs instead of calling bzero
   after allocation.
4) expand the size of the refcount from a u_short to an u_int, by using
   shorts we might have an overflow.
