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

* 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.

Applied patch from Anders Andersson as per patch sent to the mailing list.
Message-ID: <20011127110923.GB2840@sushi.sanyusan.se>

Backed the $uh() change out in script/guh.

* Optimised the search algorithms that apply to /foreach and aliasctls
  match function.
* Altered $uh() in script/guh to use the cached variables from $userhost()
  where possible.  Perhaps it's a better idea to add a new function?
* Bugfix to deban.
