This is the start of a major project to normalize the behavior of word
handling in built in functions.  The project involves stipulating that every
place that handles a "word list" define what a "word" is and use it
consistenly, and to output the same type of "words" that it accepts as
input.  This leverages /xdebug dword to control optional support for dwords
in many built in functions.

Make /window foo kill  be considered an option, so it doesn't turn into
/window describe, requested by nullie.

* Desupport dwords in a lot of builtin functions (see updates) [nullie]
* Make /window foo kill fail for want of 'foo' (see updates)

* Fix breakage for solaris found by zlonix

* Switch users of LEVEL_CRAP to LEVEL_OTHER. yay!
* Whack some unused functions and decls, make *toa() funcs return const.

* New file, levels.c, holds all the Mask and window level manip stuff.
* Move level_to_str/str_to_level, mask_to_str/str_to_mask to levels.c
* Change #define LEVEL_*'s into (int)s
* Use BIT_VALID() instead of NUMBER_OF_LEVELS, whack NUMBER_OF_LEVELS.

* Whack the now unnecessary /window auto_scrollback (mis)feature.
* Don't unconditionally unclear after rebuild, if everything still fits.

* Add the idea of a "visible" and "invisible" lastlog entry
* Always skip "invisible" lastlog entries, handle them when trimming, etc.
* Rename remove_from_lastlog() to trim_lastlog() and have it do looping

No functional changes in this commit, just some source cleanup before
I go through and wrangle the screen recalculation code into submission.

* Add $windowctl(GET <win> LINE <num>), same as $winline()

Permit /set -new_server_lastlog_level and /set -old_server_lastlog_level
which prevents epic from changing the window's level when you're connected
to a server or when a level collision occurs after a /server.  Use these
with caution, I don't know what might happen!

* Don't load "global" if user has their own startup script.
* Don't load "global" if the -q option is set, either.
* Thus, the "global" script acts as a default "epicrc" for those without one.
* THIS IS BACKWARDS INCOMPATABLE.  SEE UPDATES FOR IMPORTANT INFORMATION.
* Nix the "loading_global" variable, only used by hooks.
* Fix /on 005 so it shows the /on 005's and not all numeric hooks.

* If /window doesn't change current_window, revert from_server to orig value
* If /window changes current_window, reset from_server to cur_win->serv;

* Fix dcc compile error with --without-ipv6
* Add $windowctl(GET ref TOPLINE num) and $windowctl(GET ref TOPLINES)

Don't allow /window toplines to be a negative number!

Fix typo that caused crash.

* Nix /save and pray nobody notices.
* Implement pmatch_* stuff in alias.c to use the unified symbol table.
* Commands, functions, and expandos now 100% integrated.  HUZZAH!
* Reimplement $get(set|command|function)s() to use the pmatch_* stuff.
* So they now pick up changes at runtime. HUZZAH!
* Allow built in /set to be conditionally added to the "set bucket"
* Don't put user-created /set's in the bucket

* Create a "/set data" type (VARIABLE) which is union of (int) and (char *).
* Expose VARIABLE and variable types in vars.h for others to use.

* The second part is to init the default values once command line is done.
* Fix some warnings from --with-warns
* Fix all /set callbacks to accept a (void *)(VARIABLE *) variable
* /Set callbacks can now directly modify the /set via that variable!
* So don't allow direct setting of /set's from outside vars.c.
* Everybody must use set_var_value() which is the backend to /set.
* Whack the /IRCNAME and /REALNAME variable -- use /SET REALNAME, eh!
* Hack up /xecho -x to bide my time until i whack all those /sets it uses.
* Don't call set_input_prompt() in main() any more, it's handled elsewhere.

* New function, $tobase(<base> <num>), convert <num> in base 10 to base <base>.

* Add a counter to WNickList, for tracking queries
* Each window gets a "current query counter", to find it's current query.

* Have /window describe show nicks, channels in flat list, not one per line.
* Make sure to use the server's default quit message when closing it.
* Create a prototype of atoll() for compat systems.

* Revamp /window describe so it includes a lot more useful info.

* Make sure that servers go through SERVER_EOF state on eof!
* Track waiting/pending channels using a nicklist per window.
