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
