* New script features, cleanups, docs, etc as per KNOWNBUGS and UPDATES.

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

* 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.

* Added Tyraks /stack patch as per KNOWNBUGS.
* $afterw(), $beforew(), $fromw(), $tow() as per UPDATES.  *potential bug*
* Regress tests as per KNOWNBUGS.
* ERROR hook fix as per KNOWNBUGS.
* autoget script as per KNOWNBUGS.
* $serverctl() as per UPDATES.
* $writeb() as per UPDATES.
* /sleep as per UPDATES.

* 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.
