  Log:
  Merge subr_prof.c:1.119, 1.120, 1.121, nfs_socket.c:1.130,
  rpcclnt.c:1.14 from HEAD to RELENG_6:
  
  Acquire Giant in uprintf() and tprintf() due to the non-MPSAFEty of
  the tty code invoked from these functions.  In two cases, during
  timeout handling in NFS-related RPC client code, acquire Giant in
  the caller before other mutexes the caller might hold, in order to
  avoid lock order reversals with Giant (a recursive acquire is not
  a reversal as it won't ever wait).
  
  Correct age-old comments about uprintf()/tprintf() sleeping: they
  will never sleep.
  
  Much useful feedback from:      bde
