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

* Add /set wserv_type, either "xterm" or "screen".

Commit 556
* Change #define DEFAULT_CPU_SAVER_EVERY to 60, it needs not be 0.
* Create 'clock.c', to hold clock generation, system timers, cpu saver watchdog
* Create notion of "sys(tem)timers", callbacks for mail, notify, clock gen.
* Add 'system_timer', generalized callback for all of the system timers.
* Fix add_timer() so the 'command' argument does what the docs say it does.
* Extern 'timer_exists' so we don't try to remove_timer() and invalid timer

Commit #555:
* Add #define MINIMUM_CLOCK_INTERVAL and MINIMUM_MAIL_INTERVAL in config.h
* Add #define DEFAULT_CLOCK_INTERVAL and DEFAULT_MAIL_INTERVAL in config.h

* Add time_to_next_interval(), general form of time_to_next_minute().
* Add get_clock() and reset_clock() to replace update_clock().
* Make remove_timer() an extern function so i can delete timers. ;-)
* Add /SET CLOCK_INTERVAL and /SET MAIL_INTERVAL
* Make $T use the static clock.
* Reorganize system timers 1 and 2 into four timers:
* - CPU SAVER timer, checks for idleness, to turn on cpu saver
* - CLOCK timer, updates the status bar clock periodically
* - MAIL timer, checks for new mail periodically

* Comment stuff in words.c

Metric clock support!

Commit 512
* Add $levelwindow()
* Change default for /set new_server_lastlog_level to ALL,-DCC
  to prevent multiple servers having level dcc until i figure out why
  the code to handle this isn't working.  This value is more sensible anyways.

* New /set, /SET SWITCH_CHANNELS_BETWEEN_WINDOWS

* Revamp channel structure to hold window refnum and not window pointer
* Add "current channel counter" to channel structure.

* Fix $winbound() to work when given a window refnum
* Fix valgrind issue with $regcomp()
* Remove sanity checks from traverse_all_channels(); handled elsewhere now
* Change traverse_all_channels() with "this server" or "not this server" arg
* Nuke (Window *)->current_channel.  Handled by channels now.  HUZZAH!
* Implement /ON SWITCH_WINDOWS again.

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

* CTCP-over-DCC fix.  There are some things that confuse me about the inner
  workings here, so I'm not sure if this fix was done properly, but I did
  a few tests including a DCC send over a SED encrypted DCC and everything
  seems to tick over well.
* Unix socket configure tests as per KNOWNBUGS.
* /set flood_ignore defaulted to off.
* Tuned commandqueues.
* The 324 hook is now called for joins as well.
* %{1}D status setting as per UPDATES.
* DCC hold mode as per UPDATES.

* "Word Philosophy" alterations, /alias leak, flood checking, $glob(),
  tabkey.ce, regression tests, autoget, /fe, /fec, safe_new_next_arg, as
  per KNOWNBUGS.
* $findws(), functions (script), ${i}finditems(), $dccctl(), as per
  UPDATES.

Commit 449.  New feature added
* Split NOTIFY stuff off into its own timer
* Add #define MINIMUM_NOTIFY_INTERVAL in config.h
* Add set_notify_interval, force that /SET NOTIFY_INTERVAL >= MIN_NOT_INT

* Altered the default FLOATING_POINT_PRECISION from 6 to 16 which fixes a
  math bug.
* Melded a count argument into next_args and new_next args to cause a
  specific number of words to be returned.
* Rewrote the /alias xxx (args) form of /alias to avoid using extractw and
  to use *next_args_count instead.
* Tuned the call.xtrace alias in debug.irc.
* Extended $is_on() in guh to allow and return multiple arguments.
* Added $is_off() as a compliment to $is_on().
* Made a minor philosophical change to the way flood detection works:  A
  message is not counted as a flood if it is the first message in a flood.
  The most important impact of this is that rate calculations are more
  accurate.

Documented /exec features.

Note:  The -line* switches for the %proc mode are new and haven't been
       commited yet.

* 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.

New keybindings system coming through.  Details can be found in doc/keys
and in a few other places. :)
-wd

* New STATUS_HALFOP setting which acts much the same way as STATUS_CHANOP.
* New function $getcommands() which acts much the same way as $getsets().
  The internals for these two functions probably need to be rolled together.
* Cleanups and minor updates to tabkey.ce.

Applied the SSL patch from ay-ar.

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

The whole ROM_CHAR thing was an accident waiting to happen.  Removed.
Add /SET ALLOW_C1_CHARS to protect from the ascii char 128-159 attacks
upon XTerm and GNU Screen users.  Defaults to OFF.

Thanks go to crazyeddy and zinx for working on this in my absence.
Add /set rom_char (defaults to off) which determines whether ^R rom_char
sequences will be honored or dishonored by epic.  Dishonored sequences
are not removed; they are just mangled.  This will help you detect those
who might try to use this feature for less than noble purposes.

Re-set the ^R character to "mode 5" processing; it had been set to "mode 6"
as a stop-gap measure.

Thanks to zinx, terminal problem with ^e fixed, and the default alt_charset
is back to on.

Flipped DEFAULT_ALT_CHARSET to 0 on advice from dracus and knghtbrd.  It
seems that sending ctrl-e (ascii 5) to the display will cause terminal
cave-ins and epic to crash.  This decision was made in hops absense and
isn't final.

*sigh*

Sorry about this folks, these patches are not related to the situation at
hand.  They accidently got rolled into that hastily applied update, and
none of us "on duty" right now know how to roll them back.

Untouched, these should not effect the workings in any way.  Service will
resume as soon as possible.

This particular one should fix the original problem.

Hurried patch.  This rolls back the $read() patch for now.

Add /set auto_rejoin_connect -- this controls whether epic will try to
rejoin your channels when you are disconnected from a server *AND EPIC
WOULD ORDINARILY TRY TO REJOIN YOUR CHANNELS*.  This has *ABSOLUTELY NO
EFFECT AT ALL* in those cases where epic has thrown away your channels
and has no intentions of rejoining them.  This is only a way for you to
reduce current functionality, there are no bugs fixed with this.

Two things:
* Remove /set notify_handler which didn't do anything.
* Rewrite /lastlog so i understand how it works.
  Big new feature, -regex, to support regex searching on lastlog!
* Commit #75.

Remove the broken and undesirable and much loathed and hated
"dcc checksum" misfeature a good bit ahead of schedule.  Good riddance.
