getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument. We can
handle this case with the "default" failure case with no loss of
legibility. Hence, remove all the redundant "case '?':" lines.
Prompted by dlg@. With help from dlg@ and millert@.

Change several instances, most of them to the usual -width Ds.

rediscovered that telnet has more more signal race conditions and trashing
of global state than all the rest of the openbsd source tree (where signal
races have either been fixed or marked with "XXX signal race". I don't
feel like being a hero here today, so I'm fixing a whitespace error in an
unrelated file.

value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

telnet would perform a gethostbyname on close/quit commands
when the machine hostname is not a fully qualified domain.
This behavior added on 12-March-98 breaks the current pledge
that "dns" operations are not needed after establishing
a connection leading to a coredump from telnet when
quiting or closing an existing connection.

While here, there is no option to pass a different tos, and no other
use of the "tos" variable out of tn(), so move the "tos" variable in tn()
and assign it the right value from the start.

kettenis@ agrees with reverting to fix the regression; we can consider a
better diff afterwards but clearly this is a sensitive area.

possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution. These are the files confirmed
through binary verification.

troff displays these as typographic quotes, but nroff implementations
almost always print them literally, which rarely has the intended effect
with modern fonts, even in stock xterm.
These uses of `` '' can be replaced either with more semantic alternatives
or with Dq, which prints typographic quotes in a UTF-8 locale (but will
automatically fall back to `` '' in an ASCII locale).
