  Log:
   - Turn all explicit giant acquires into conditional VFS_LOCK_GIANTs.
     Only ops which used namei still remained.
   - Implement a scheme for reducing the overhead of tracking which vops
     require giant by constantly reducing the number of recursive giant
     acquires to one, leaving us with only one vfslocked variable.
   - Remove all NFSD lock acquisition and release from the individual nfs
     ops.  Careful examination has shown that they are not required.  This
     greatly simplifies the code.
