* Phase two of larne's patch is to isolate features that require job control
* You can #define NO_JOB_CONTROL to turn off fork/exec type stuff.
* Soon, the configure script will auto-grok this.

* Add /SET DEFAULT_REALNAME and DEFAULT_USERNAME
* Add scripted /set realname and /ircuser in builtins for backwards compat.

* Add arg to panic() controlling whether panic is sent via QUIT (rb black)

* Stage 2 -- start eliminating "optimizations", use update_input() for redraw

* Add /set mail_type (MBOX or MAILDIR) to control what we check for mail.
* Make rebuild-scrollback a toggle flag instead of an operation.
* Teach update_all_windows() how to rebuild scrollback
* Write some preliminary code for the unified lastlog

* Lay the foundations for nonblocking ssl connection (not supported yet)
* Change SEND_LINE to do SCROLL_FORWARD if we're in scrollback mode
* Add support for maildir mailboxes.
* Fix crash with 042 numeric.

* Switch users of LEVEL_CRAP to LEVEL_OTHER. yay!
* Whack some unused functions and decls, make *toa() funcs return const.
* Roll get_window_by_name() into get_window_by_desc(), it's only user.

* 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
* Allow user to replace one user-created /sets but not builtin sets.
* Allow mangling of ALT_CHAR -- how did this ever get missed?
* Fix $currchans() so it works the way the documentation says it does.
* Fix some const correctness issues, introduce others. bleh.

* Make stripcrap(ALL) exclude "ALL_OFF", so I can...
* Fix bug with $stripcrap(ALL,-BOLD ^B^B^Btest). (rb BlackJac)
* Make the #define Char const char thing global to all of epic now.
* Whack /set scroll.
* 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.
* Break init of /set's into two parts, one to malloc() the set data
* 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.
* Whack /set logfile callback, since nobody seems to have missed it.
* Whack the "number" (float) data in /set since i wasn't gonna use it.
* Whack the "GLOBAL/CHANGED" tracking in /set's.  Tell me if you miss this.
* Unify output of /set values as "[New|Current] value of <var> is <val>"
* Don't limit the size of /set continued_line, this will be revisited soon.
* Quick and dirty hack to work around adm's bug, will fix this later.

Well, at least it compiles again, but I think i still need at least one
or two sweeps of the code to make sure I got everything proper.

*********** DONT RUN THIS -- IT'S WORK IN PROGRESS -- DONT RUN THIS ***********
* Import epic4 commits 674 through 692, inclusive.
* Import epic4 commits 693 through 710, inclusive (epic4-2.0 final)
* Change _X and _Y macros to LEVEL and LEVELMASK for linux (sigh)

* Convert message_from to int masks.
*********** DONT RUN THIS -- IT'S WORK IN PROGRESS -- DONT RUN THIS ***********

EPIC5-0.0.1!  Huzzah!

Make message_from() work off of a stack; use panics to guard against
unmatched message_from()s, and other wackiness.

* Numerous updates/changes/fixes to DCC, functions, scripts, /EXEC, the
  new math parser, as per UPDATES and KNOWNBUGS.

One potential incompatibility is in the change to $open(). (as per UPDATES)

Fix it so /set mail 3 and /set mail 4 don't cause panics.

Teach all the /set callbacks to take a (const void *).
This fixes a bad-c problem with /set!

* Add "ON/OFF" toggle set variable to the system timer data.
* Create 'update_system_timer' which uses the "toggle" var to run or stop timer
* Merge '(start|stop)_system_timer' into 'update_system_timer'
* Nix #define MINIMUM_(NOTIFY|CLOCK|MAIL)_INTERVAL since we can't stop that.
* Do not enforce minimums for /SET *_INTERVAL since user could get around it.
* Track "last event" time, maybe I'll use that in the future
* Reset "now" global variable before calling timer callback.
* Fix null deref bug with $($$)
* Add default binding to ^G to "self_insert" for beeps.
* Do not enforce MINIMUM_NOTIFY_INTERVAL in do_notify()
* Don't include exec.h from screen.c
* Add 'number' (floating point) field to /set's
* Add FLOAT_TYPE_VAR type for /set's, using 'number' field
* Update all the /set entries to include a default 'number' field.
* Add get_float_var() to get the 'number' field in a set.
* Add set_float_var() to set the 'number' field in a set.
* Teach set_variable() about FLOAT_TYPE_VAR sets.
* Teach save_variables() about FLOAT_TYPE_VAR sets.
* Teach get_string_variable() about FLOAT_TYPE_VAR sets.

Commit 558
* Don't allow user to /window number in a window with a channel (avoid panic)
* Make check_mail return a (const char *), fix status_mail().
* Modularize/reorganize mail checking, with mbox reference implementation.
* Automatically /set mail 0 if the user's mbox can't be found.

Maybe I fixed a bug, maybe I didn't.

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
* Redo dependancies because clock.h exists.
* Add code to bootstrap mail systimer with /set mail
* Add code to bootstrap clock generation with /set clock
* Add code to bootstrap notify handling with /set notify_interval.
* Start enforcing "NOTIFY_INTERVAL" again in do_notify() to avoid excess flood.

Convert m_strdup() to malloc_strdup().

* 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!

Nominally remove all uses of "unsafe" functions: (Commit 506)
* Convert all uses of strcpy() to strlcpy()
* Convert all uses of strcat() to strlcat()
* Convert all uses of strmcpy() to strlcpy()
* Convert all uses of strmcat() to strlcat()
* Convert all uses of sprintf() to snprintf()
* As much as possible, use 'sizeof var' in snprintf/strlcpy/strlcat.
* Qualify the size of some global vars so we can sizeof() them.
* Nuke strmcpy(), strmcat(), strmcat_ue(), strmccat(),
* Change strmopencat() to strlopencat().
* Change strmpcat() to strlpcat().
* Fix switch_hostname so it doesn't return a (const) string.
* Fix TimerTimeout so it doesn't return a (const) Timeval.
* Change things like (ret) to do ret while (0); for when "ret" is "{}".
* Fix initialization for load_level
* Stop passing in static strings into io(), so we can modify them.
* Make messages passed to io() more informative to the user.
* Fix CTCP FINGER handler not to assume (struct pw) strings can be overwritten.
* Use (socklen_t) and not an (int) for socket sizes.
* Don't return a value in a void function...
* Don't use return value of process_dcc_chat_ctcps() for assignment.
* Don't put semicolons after function bodies
* Fix $getopt() to save 'input_size' so we can use it with strl*().
* Convert all uses of stpcpy() to strlcat() and strlopencat().
* Nix checks for stpcpy() in configure -- regen configure.
