  Log:
  Add a per-thread ucred reference for syscalls and synchronous traps from
  userland.  The per thread ucred reference is immutable and thus needs no
  locks to be read.  However, until all the proc locking associated with
  writes to p_ucred are completed, it is still not safe to use the per-thread
  reference.
  
  Tested on:	x86 (SMP), alpha, sparc64
