* DO YOU THINK YOU CAN RE-ORDER AN ARRAY AND NOT CHANGE THE #DEFINES DUMMY?

* Add SEDSHA cipher type, which is better than SED, and always available.
* Add my_sleep|isreadable|iswritable() funcs to phase out rogue selects()h
* Add support for multiple concurrent servers to /encrypt. yay!
* Store the length of the Crypt key within the key itself.
* This moves us closer to being able to decrypt arbitrary data.
* Test all of the cipher types, incl. compat of CAST with ircII.  All set!

___ WARNING ___ This stuff is all wildly un(der)tested.
I will get to that soon!  But I'm too excited about this to sit on it.

* Add AESSHA256 support (AES256 using the SHA256 digest of your passkey)
* Rename "EXTCRYPT" to "PROGCRYPT"
* Migrate SED support from crypt.c to crypto.c
* Integrate SED and extprog support into the mainline [de]cipher_message()
* Refactor [de]cipher_message() to be less lame.
* Support "anycrypt" support (AESSHA, AES, BLOWFISH, CAST5, SED, PROG)
* Include sha256 implementation from Karll.  Thanks Karll!
* Unify the ctcp handling of all crypto ctcps
* Add $sha256() function to test sha support (digest)
* Make funcs in crypto.c static and just expose [de]crypt_msg().
* This finishes the divide between crypt.c (front end) and crypto.c (back end)
* Fix a gazillion compiler warnings and sort out const/unsigned char issues.

AES support!

* Support cast5/blowfish encryption a la ircII.
* Fix build for non-ssl users.

Commit 541
* Move #define CTCP_* into ctcp.h
* Add /xdebug extractw_debug
* Move #define LOCAL_COPY and SAFE into irc_std.h
* Create compat.h, move all the compat.c decls into there (from ircaux.h)
* Create network.h, move all the network.c decls into there (from ircaux.h)
* Create words.h, move all the words.c decls into there (from ircaux.h)
* Include "compat.h" and "network.h" in ircaux.h
* Do another round of make depends
* Rename 'search' to 'search_for'.
* Fix the metric clock hooking /on timer too much.
* Revamp words.c, to support passing word quoter (' or ") as an argument.

* 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!

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

Commit 436
This commit is deceptive because it is huge in scope but can be explained
pretty simply.

* Const correctness improvements.
* Invert the meaning of 'new_check_flooding' to return TRUE if flooding.
* Revamp funny.c, /list, /names, /mode reply handling.
* Remove unused joined_nick, public_nick
* Change got_initial_version_28() arguments singly and not an array
* Change signature of protocol handling to take "command" as an argument
* The above change cascades to a lot of other changes.
* Allow the /msg'ing of @W<refnum> to msg a window's refnum.
* First round of larnification (Protection against unexpected server data)
* This involved substantial rewrites of parse.c, and numbers.c
* Now "fake" stuff goes through /on odd_server_stuff.
* Fix /on invite so it takes 3 arguments, not 2.

* Added functions $asciiq() $chrq() $exec() $timerctl() $tcl() $winline()
  and $floodinfo().
* Altered the two argument version of $read() to ctcp quote the strings it
  returns.
* Added sets FLOOD_RATE_PER and FLOOD_MASKUSER.
* Altered the "accept" mode of the dcc_raw and dcc_connect hooks to refer
  to the local port instead of the remote port.
* Added a "-closein %proc" switch to /exec.
* Altered the arg list mode of /alias to use extractw instead of next_arg.
* Added the documented "words" argument to the above.
* Tuned autoget, mudirc, tabkey.ce and commandqueues.
* Altered /pretend to not chop the string.
* Set about rewriting the flood detection and then decided that it's better
  off being a script.
* Moved the function macros to their own file (functions.h) and replaced
  all the copies that are strewn throughout the source with an #include.
  The exception is array.c which broke when I tried it.
* Moved the ctcp enquoting/dequoting functions to ircaux.c.
* Added some command/function ordering checks to funcs/regress, and a check
  for all the functions that are undocumented.
* Rewrote function chanmodetype() so that it doesn't have all those flakey
  buffering things.  Hopefully it's readable now.  The significant change
  is that if a mode character appears twice in CHANMODES, the first one is
  returned instead of the last.
* Added EPIC::call() in the perl routines and an equivalent under tcl.
  this is designed to call a $function() directly, but it isn't really that
  fast, so I might rip them out again.
* The /wait internals used to store a few other settings, which were taken
  out, so I put them back.
* Fixed a few problems with normalize_filename() around the place.
* Fixed a bug with /timer in which it would never show the timers after a
  callback.

* Applied Ay-Ars patch (with a few modifications) which fully melds ssl
  into the server spec, which is now server:port:pass:nick:group:proto
  where proto currently is "irc" or "irc-ssl".
* Removed -ssl flags from "/window server" and /server.
* Ay-Ars patch also includes a new function, $servertype() which returns
  the proto field by way of extrapolation, (it is not the exact text
  entered into that field).

* Entering a server spec in a /server or "/window server" that currently
  exists, but which has different additional field values normally
  alters the current spec to conform to the new spec.  This doesn't work
  with the proto field.  This is probably a bug.

I am somewhat uncomfortable with all of this.  I would like to alter
add_to_server_list to be the one true reference for decoding the server
spec and simplify the other functions to only breaking it into server,
port and "additional".  This may be too big a change currently.
