    kernel - misc MPSAFe work
    
    * prisoncount, prison_hold(), and prison_free() are now MPSAFE
    
    * Remove spinlock from ucred
    
    * Fix cr_ref race in crfree(), and crfree() is now fully MPSAFE.
    
    * cache_hold(), cache_copy(), cache_changemount() are now MPSAFE.
    
    * cache_drop() is not yet MPSAFE in the 1->0 transition case.
    
    * nlookup_init() is now MPSAFE
