including all the stuff already pushed into epic4.

* Add /on signal (pegasus)
* Fix build on interix (twincest)
* Fix compile warnings and a c99-ism
* Fix another panic() causable by /echo. ugh.

* Use $unsplit() to convert $splitw() into a uword list (see UPDATES)
* Fix ./configure --without-ipv6 to allow compiling on opensewer.

--- This is a bunch of stuff I've been sitting on while I wait for howl to
finish what he was doing. ---

* Add support for ./configure --localdir
* Add support for ./configure --with-iconv=/usr/local

Normalize the BUILT_IN_BINDING/BUILT_IN_KEYBINDING macros.

* Make the build work with socks5 again, for freebsd ports support
* Add malloc_strcat3_c().
* Optimize malloc_strcat_word_c

* Include <stddef.h> if we can, for no particular reason...
* Nix now unused mangle_line(). yay!
* Use (intptr_t) instead of (intmax_t) to treat pointers as integers...
* Try to handle failures from the dns helpers with more grace.

* Use "intmax_t" for dcc byte counts, eliminate notion of "packets".

* Change %D status bar expando to look like "0.1Kb of 2.3Mb" (no packets)
* Choke on dcc send offers that don't have file sizes.
* Make a feeble attempt to handle 32-bit rollover on dcc get's > 2gb.
* Use "intmax_t" for the new math parser, 64 bit int's ahoy!
* Use INTMAX_FORMAT to format intmax_t's in new math parser.

Add configure glop for intmax_t for c90 systems.  Will start using later.

* Add --with-multiplex=[select|poll|kqueue|pthread] to configure
* Check thread-safety of SSL in configure when using pthreads.

* Don't call set_input_prompt() in main() any more, it's handled elsewhere.
* Whack /set logfile callback, since nobody seems to have missed it.

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

* Add arc4random stuff to compat.c -- will be used later!
* Fix $realpath() to use normalize_filename() so it gets realpath() fix.

* Fix bug with /QUEUE -delete
* Remove unused variable in window_scroll().

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.

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

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

Yet another swath of changes in The Great IPv4 Cleanup.  This time I
took a broad hatchet to the resolver-assistant functions in network.c.
Using modern techniques really increases readability and makes it look
less like a hack.  Making good progress!

Next round of in_addr/u_short -> sockaddr_in conversions, along with some
other minor details.  As far as i know, this shouldn't break anything,
but I don't promise that.  Save your old binary first!
If anything is really bad, let me know.  I'll fix it ASAP.

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 in the deep...

Two new functions in ircsig.c: "block_signal" and "unblock_signal"
which use sigprocmask() which I hope everybody has!

Based on a discussion with |Rain|, block the SIGCHLD signal before we
go waitpid()ing, and then unblock it when we're done.  This cleans up a
race condition that might happen if two of our child processes die in the
same time slice; we would only get one call to our SIGCHLD handler, but we
would have two children to reap; "dead_children_processes" would then be
a negative value and bad things would occur.  Now we handle SIGCHLD as a
condition rather than a discrete event; whenever we get a SIGCHLD, the next
time through a sequence point we block SIGCHLD, reap our children, reset
"dead_children_processes" to 0 and then unblock SIGCHLD and go on our way.

Add MIN() and MAX() macros in irc_std.h.

More complete support for random local ports; /set random_local_ports now
cooperates with /setenv EPIC_USE_HIGHPORTS=1, and it works on freebsd,
openbsd, and linux, such as it is.

* Fix server assignment in /exec so it works in /on's again.
* Fix failsafe declaration for MAXPATHLEN for hurd in irc_std.h and glob.c.
* Fixes to make dcc-over-ctcp-over-dcc work again (|Rain|)
* Fix $querywin() so it can take a second argument, a server ref (for scromp)
