Let us never speak of this commit again.

Wrapper for atoll() for freebsd-stable and stuff.

Unconditionally do (long long) integer math in the new math parser if
your system supports (long long).  I suppose on some systems this will
make math slower, but that seems like a small price to pay for having
integers that will actually support IP addresses!

$info(o) will inclue the letter 'l' if the host client is working with
64 bit integers in the new math parser.

Please note that the old math parser has not changed, and still only
supports 32 bit integers, and that won't change for backwards compatability.
If you really really really need 64 bit integers, think about changing to
the new math parser.

Fix it so you can compile on systems without (intptr_t) again.

Include <stdint.h> and <inttypes.h> if they exist.

Add support for clock_gettime() which is the posix version of gettimeofday().

* Rename 'dcc()' to 'dcc_cmd()' so we can use dcc as variable
* Garbage collect unused 'irc_path' global variable.
* Add --with-warns to configure to do FreeBSD "WARNS" like compiler checks
* Many hundreds of changes to improve the "quality of code" in epic, including:
* - Treat all literal strings as (const char *) and fix const correctness.
* - Mopping up all remaining const-correctness issues
* - Do not "launder" a (const char *) to a (char *) in string searches, (ala
    strchr) but rather return a ssize_t offset value.
* - Particular, MatchingBracket() returns (ssize_t) and not (char *).
* - Eliminate all "shadow" variable names by changing them to something else.
* - Eliminate most function decls that do not include a prototype list.
* - Add prototypes for all extern functions that are missing them.
* - Ensure most function pointers include a prototype list.
* - In term.c, most of those (char *)'s are really (const char *)'s.
* - Explicitly specify 'static' functions as 'static'
* - Ensure every function is either 'static' or has a prototype.
* - Eliminate (unsigned) < (signed) type comparisons.
* Hopefully you should not notice any changes!

* Nuke strmcpy(), strmcat(), strmcat_ue(), strmccat(),
* Change strmopencat() to strlopencat().
* Change strmpcat() to strlpcat().
* Fix switch_hostname so it doesn't return a (const) string.
* Fix TimerTimeout so it doesn't return a (const) Timeval.
* Change things like (ret) to do ret while (0); for when "ret" is "{}".
* Fix initialization for load_level
* Stop passing in static strings into io(), so we can modify them.
* Make messages passed to io() more informative to the user.
* Fix CTCP FINGER handler not to assume (struct pw) strings can be overwritten.
* Use (socklen_t) and not an (int) for socket sizes.
* Don't return a value in a void function...
* Don't use return value of process_dcc_chat_ctcps() for assignment.
* Don't put semicolons after function bodies
* Fix $getopt() to save 'input_size' so we can use it with strl*().
* Convert all uses of stpcpy() to strlcat() and strlopencat().
* Nix checks for stpcpy() in configure -- regen configure.

Okay.  User input is now handled specially, and parse_command() will not
accept incomplete command names anymore.

Another merge.

Fix various specious warnings from gcc, also, don't test for "sun_len"
in configure; use "sa_len" test for that.

Yikes.  Merged to become consistent with HEAD.  Sorry for all the commits,
I'll be quiet again soon. :)
-wd

* Configure now does a deeper search for the perl libs.
* Rebuilt configure.

* Fix for NAMES processing.  Discovered by Paladin.

Commit #427
* Add -l<tcl> to the front of $LIBS so -lm can come after it
* Look for SSL stuff in default location before hunting for it in /usr/local.
* Reset $withval after check for perl so --without-perl doesn't --without-tcl
* Make first arg of cvtchar() a (const char *) to silence warning.
* Move 'this_sucks' label to a place where it is legal.
* Make check_val() cope with NaNs and INFs more graciously...
* Fix null deref with /lastlog -c
* Update the input line in set_update(), not the caller
* Do update the input line when redrawing status
* Change make_status() to return a success/failure value.

* Nuke the now unecessary "in_window_command" global variable.
* Fix bug where <scrollback> + <scrollforward> left you in scrollback mode.
* Force init of Window->lines_held = 0 even though that shouldnt be needed.

Fix compile errors in configure.in.  These were my fault.

Rebuilt configure.  perl and tcl support should default to on for BSD and
Linux now.

Regenerated autoconf.

* Add checks/workaround for linux's broken realpath(). Bleh.
* Add arc4random stuff to compat.c -- will be used later!
* Fix $realpath() to use normalize_filename() so it gets realpath() fix.
* Add $serverctl(SET <refnum> PRIMARY) to set primary server.  User beware!

* #include <unistd.h> for configure check for sys_siglist[] for netbsd.

Check for getaddrinfo() and getnameinfo() in configure
otherwise we can't do ipv6 lookups. doh!

Update documentation prior to epic4-1.1.6 release
Add "HAVE_GETSERVBYNAME" check to configure stuff.
Remove /SET RANDOM_LOCAL_PORTS which has gone away.
Fix some layout issues with gailib.c and change two function names.
Fix comment issue with ircsig.c
Fix uninitialized variable issue with keys.c
Remove mention of /SET RANDOM_LOCAL_PORTS in network.c

Add GAILIB, a bsd licensed getaddrinfo/getnameinfo implementation for
ipv4 only systems.  This was lifted from ruby, who lifted it from WIDE.
Add #ifdef's as necessary to compile on non-ipv6 systems.

Change configure script's generation of "sig.inc" to make sys_siglist a
static global variable, to avoid multiple declarations which would fail
at link time.  Reported by da5id.

Lots more work on the ipv6 front.  Remove the last of the vestiges of the
old historical address handlers (inet_ntop/inet_pton/inet_aton/inet_ntoa).
Now everything, and I mean EVERYTHING goes through inet_strton and inet_ntostr
which are just fancy front ends to getaddrinfo() and getnameinfo().  Quite a
bit of EPIC is already family-independent, but there is still some left to be
clubbed into submission.  The project to add support for IPv6 is now about
75% complete!

Perversely enough, the only thing stopping DCC from being essentially 100%
IPv6 capable is the inability to send an IPv6 hostname through a handshake
without breaking the standard...

Changes by zinx for handling of 'configure --with-ssl'

Huge major commit #1 in the great IPv6 support addition...
Rather than include all of the changes here, read KNOWNBUGS changes.

It appears as though the last two changes to configure.in did not result
in the configure script being recreated and committed -- do that now.
This introduces configure changes to 'ssl' and the check for 'socklen_t'.
Also, fix a compiler warning in status.c.

Fixes inspired by first wave of testers
1) Fix casts to inet_anytop()
2) Fix configure to check for socklen_t, default to 'int'.

This is a huge monster commit -- I put the particulars of the commit in
KNOWNBUGS.  I will only say here that this fixes a lot of issues with
DCC and introduces a lot of protocol independance into the networking API
that epic works with.  Good things will continue to come in the future!

Let's try another approach to the "find out if sa_len exists" problem.

Check (struct sockaddr) for sa_len, and use this as a hint as to whether
sockaddrs have a "length" field in them.  I will phase out the (now obsolete)
check for HAVE_SUN_LEN in configure, once i'm comfortable that checking for
HAVE_SA_LEN is sufficient.  Whack up the (struct sockaddr_storage) to honor
the HAVE_SA_LEN value probed by configure, as requested by Q (Kurt R.).

Regen configure.  This brings the ssl stuff into play from CE's last commit.

Drums...
Drums...
Drums...
Drums in the deep...

Have 'configure' check for the worthiness of SNDLOWAT setsockopt option
so that the linux users stop griping to me that they don't like to see the
error message that linux's braindamage causes.

Rebuilt the configure script after applying SSL patch.

Applied the SSL patch from ay-ar.

Details are in README.SSL.  This works well at this point, but there may
be teething problems.

Add compat functions for setenv() and unsetenv().  Unfortunately,
if your system lacks these functions, setting environment variables
causes a memory leak, and you just plain flat out can't unset environment
variables.  These are defects in the API (or in the OS, whichever one you
prefer to blame) and do not represent bugs in EPIC.

Oops. I forgot to re-run autoconf. *blush*.

Re-run through autoconf to pick up -g -O instead of -g -O2.

Oh yes...  And rebuild the configure script..
