usr.bin: remove unnecessary lint comment CONSTCOND

Since 2021-01-31, lint no longer warns about 'do ... while (0)'.

No functional change.

Avoid using common symbol definitions.

get rid of equal(), use {s,g}etprogname().

branches: 1.32.2; 1.32.8;
Use __dead. Make a bunch of local functions static.

fix language

Move #include <libgen.h> from tip.h to the place where it's really needed.
From: Slava Semushin <php-coder@altlinux.ru>

Moved ctype.h from header to source file in usr.bin/tip.
Also removed unused getopt header.

Patch contributed by Slava Semushin <slava.semushin@gmail.com>
in private mail.

pass lint; from Anon Ymous

Use closefrom, don't iterate over file descriptors from 3 to 20.

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.

Pass a little lint.

delinting. more needed. (lint found some real bugs that I haven't fixed yet.)

Wwwwwwww! Do not remove variables from the vtable in vars.c without
changing the indices in tip.h -- what a terrible design.

Okay, "design". Fine. Whatever. ;-) Now we don't dump core all the time.

Remove vestiges of the ACULOG support. It depended on the suid support
(which is now gone) and it is woefully obsolete -- if something
analogous is ever needed in the future, syslog is the way to do it.

Remove support for uucp style locking.

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.

ANSIfy decls, de-__P, clean trailing whitespace

Fix the conditional compilation on ACULOG so it actually works.
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.

New 'cu' command-line handling, derived from Todd Miller's in OpenBSD,
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).

pull the following change from OpenBSD
and bump date of the manpage.

date: 2003/09/20 18:15:32; author: millert; state: Exp; lines: +4 -2
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.

constify and warns = 3

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

synchron*, not sychron*

Spell "privilege" correctly (correct spelling from Jonathan Stone).

<sys/dir.h> -> <dirent.h>
<sys/file.h> -> <fcntl.h>

- KNF
- use snprintf
- be safe with buffers (change prompt() to take a size_t len arg for this)

Rename an internal function who's name collides w/ pwrite(2).

Include <time.h>, needed for various definitions. Also, per KNF, don't include
both <sys/param.h> and <sys/types.h>; the former is sufficient.

WARNSify, KNFify, using ANSI string functions, cleanup .Nm usage

Add boolean for dc flag

Change booleans from char to int so that comparisons against negative
values work as expected on systems with unsigned chars.

replace old zzhack structure (YUCK!) and number(), boolean(), character(),
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.)

Convert to termios (from Scott Reynolds; PR#1621).
8-bit patches (from Matthieu Herrb; PR#1384).

Merged with 4.4lite.
Changed to conform to NetBSD's new RCS Id convention.

Add RCS identifiers.
