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.
This means we can get rid of the suid/sgid parts of the code (which
have been removed). The program is now installed with normal permissions.
To prevent accidents, we now flock the tty line, attempting to get an
exclusive lock.

Turn it off by default -- it hardly saves any space, but it's
one of the reasons why the executable is installed setuid, and
other versions of tip/cu don't write a log file anyway. We can
add syslog support later if we ever really want this back, the
file-writing is all encapsulated in log.c.
but with some long options added for Taylor 'cu' compatibility, and
with some bugs fixed (in particular, the handling of -# now works as
documented and does not overwrite argv).

Implement hardwareflow varable in tip(1) like Solaris and hf in /etc/remote.
Based on PR 3411 from Matthew Gream
Also document "tandem" variable (XON/XOFF) in tip man page.
and address() macros with new macros of the same names (to get values),
and macros with those names but with "set" prepended and which take a
second argument (to set values). The new macros use type casts to do
type conversion, which is much cleaner than using a union and making
endianness-related hacks to get the right 'short's and 'char's from
the right array indices. (YUCK! again, for good measure.)
