	src/usr.bin/tip: cmds.c tip.c tip.h tipout.c

Log Message:
Replace abuse of SIGIOT, SIGEMT, SIGSYS for communication between the
TIPIN and TIPOUT processes with a third "attention" pipe.  While we're
here, fix a few other minor nits like the hardcoded use of fd 3 in
consh().

Now ~+/~C appear to work.  This must have been broken for years.
