* Allow Getaddrinfo() and Freeaddrinfo() to be called extern.
* Track writable sockets in 'global_max_fd' too.
* Keep a list of AI's for server addresses in the server code
* When server connection lost before registration, use the next AI
* Implement set_server_status(), which controls where server is in lifetime
* Nix reconnect(), which is replaced by close_server + set_server_status().
* Nix server_reconnects_to(), we no longer reconnect to servers.
* Make /xdebug server_connect the default for this commit at least
* Call window_check_servers() every time through io(), because...
* Make window_check_servers() look for disconnected servers and restart them.
* Add add_mode_to_str() which adds a channel or usermode to a string (sorted)
* Make usermodes use add_mode_to_str()
* Make channel modes use add_mode_to_str()
* Now modes are not stored in bitmasks, not hard-coded at compile time. HUZZAH!
* Nix "inactive" field in channels, channels are thrown away at disconnect
* Don't allow channels to move between servers, natch.
* Nix all the code to handle disconnected channels and such.
* Use change_window_server() to move windows to new servers, because...
* Make window_check_servers() auto-close windowless servers.
* Make change_window_server(<server>, NOSERV) cause a disconnect from <server>
* Don't honor /set auto_reconnect, we don't ever reconnect.
* Fix printf() error in /on kick default output
* Add new server state, SERVER_RECONNECT which means "i can be connected"
* So now SERVER_CLOSED means "don't reconnect me"
* Allow /server, /window server, and /reconnect to change CLOSED -> RECONNECT
* Make server connections nonblocking.
* Server connections are now nonrecursive, nonblocking, multi-protocol. HUZZAH!
* GC a bunch of server code dealing with reconnection we don't use now.
* Don't call window_check_servers() other than io() for sanity reasons.
* Make /window server just change server, let w_c_s() bootstrap connection
* Remove many window->channel->server sanity checks.

Make 'empty_string' (const char []).  Now we're cooking with gas!

EPIC5-0.0.1!  Huzzah!

Make message_from() work off of a stack; use panics to guard against
unmatched message_from()s, and other wackiness.

* Nix auto-append-of-$* feature (args_flag to expand_alias/parse_inline)
* Fix provided scripts to add $* when necessary.
* Fix up Makefile, configure, et al, to use epic5/ directories.

Fix some more problems in the pf loader.

* Add /ON WINDOW_BEFOREKILL
* Another iteration of the 'notify' script, hooks the system's /ONs now! =)
* Put a space in place of a newline in the PF loader.
* Always ignore spaces after semicolons in parse_line (the {} parser).
* Some compiler warning fixes from rain.

(*gulp*) Some changes for fudd.
* Add /ON WINDOW_COMMAND, hooked after every /window command, $* is refnum.
* Add concept of "fixed" or "frozen" windows when you SKIP ON FIXED ON
* Fix /window kill to not kill the last "non-fixed" window
* Fix /window hide to not hide the last "non-fixed" window
* Allow /window kill to kill a "fixed" window, but not the last window.
* (*gulp*) I hope all of the above works!
* Fix $windowctl(REFNUM ...) it was out of order with REFNUMS
* Make /xecho -l override the "who_from" target and always send to the level

Implement infinite recursion detector and thwarter.  It requires a #define
in config.h, the future of which I have not decided yet.

* Numerous updates/changes/fixes to DCC, functions, scripts, /EXEC, the
  new math parser, as per UPDATES and KNOWNBUGS.

One potential incompatibility is in the change to $open(). (as per UPDATES)

Implement "privleged yells" which allow syou to do /set debug 7 at the
same time as /set output_rewrite.  Yea~!

* Add $servernick(<global>) to return the client's global nickname
* Update tabkey.jm to latest version
* Add new ircII-compatable /window hold_mode thingee.
* Add /set hold_slider, /window hold_slider
* Add 'hold_mode' script, implements ircII-like /set hold_mode[_interval]
* /XEVAL -- ends eval option processing, like how /xecho does it.

Commit 581
* Fix /dcc chat nick -p 4444
* Return empty string if you do $aliasctl(pmatch <bogus> <whatever>)
* Update some copyright notices.

* Fix buffer overrun crash with CTCP UTC.

* Fix time functions to take (const Timeval) if they don't change the arg.
* Create a special handler for /squit to avoid sending QUIT * to server.
* Protect some IPv6 stuff i added recently to dcc with #ifdef INET6.  Ooops.
* Hack up $repeat(<num><space><space>) so it works again. ugh.
* Hack up /set <variable><space><space> so it works again.  ugh.
* Dont allow /timer -repeat -1 0 because that busy-loops.
* Add shell of $windowctl() which will be filled in going forward.

Fix up /load to honor the /return command so you can abort early from
within a /load'ed file.  See 'pf-loader' for details on why you would
want to do this.

Commit 551 -- second to last commit for this project -- the big one!
* Roll in the new universal_next_arg_count() and attendant macros.
* Comment out some deprecated function decls in ircaux.h
* Do another round of make depends.
* Modify alias arglist code to use the new universal_next_arg_count() stuff
* Convert dequote() to dequoter().
* Convert new_new_next_arg() into new_new_next_arg_count().
* Comment out deprecated functions in ircaux.c -- will be deleted later.

Overhaul of malloced string handling functions:
* Convert m_[s]c3cat[_s]() to malloc_strcat_wordlist_c()
* Nix m_e3cat(), m_s3cat(), m_s3cat_s(), m_3cat()
* Nix m_ec3cat(), m_sc3cat(), m_sc3cat_s(), m_c3cat().
* Convert m_dupchar() to malloc_dupchar().
* Convert m_strndup() to malloc_strndup().
* Make malloc_strcpy/malloc_strcat/malloc_strcat2/malloc_strcat_wordlist macros
* Convert m_2dup() to malloc_strdup2().
* Convert m_3cat() to malloc_strcat2[_c]().
* Convert m_3dup() to malloc_strdup3().
* Convert m_ec3cat() to malloc_strcat2_c()
* Use strlcat_c() in $repeat() instead of strlcpy(). whee!
* Sanity check first arg to $regcomp(), to avoid crashes.
* Don't pass NULL to bsearch(), even if 'nmem' is 0 [$remws()]
* Nix the original malloc_strcpy (supplanted by malloc_strcpy_c)
* Comment out all the deprecated functions

Convert m_strdup() to malloc_strdup().

* Misc bugfixes as per KNOWNBUGS.
* This patch involves renaming crypt.h to sedcrypt.h.

* 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
