* Add support for /ignore'ing a server (for undernet)
* Add --without-wserv flag to configure (see UPDATES)
* Add checks in configure for posix-like job control
* Add support so no job control -> no wserv support.

* Fixed an apparent typo in getnrolitems in data_array.
* Fixed a bug in autoget where it wasn't actually starting a download.
* Fixed yet another bug in commandqueues involving double quote dequoting.
* This covers for an apparent bug in $shift() which should automatically
  dequote quotes (unfixed).
* Added USER1 - USER10, OPERWALL and SYSERR levels to the ignore system.
* Added ":" hack to /notify as per UPDATES.

* Make /xecho -w -1 go to the current window, for compat with epic4 (rb Black)
* Make the /server list show the vhost you're using.
* /LOADing an executable file results in a warning and not an error.
* Fix input line so it doesn't display hidden contents after ^L (rb wjr)
* Add a $strptime() function, but I still need a strptime() compat version.
* Add $ignorectl(SUSPEND) and $ignorectl(UNSUSPEND) to turn off ignores.

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.

* 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.

* 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 hardcoded level_types char array. yay!
* Change users of "LEVEL_CURRENT" into "LEVEL_NONE" and whack "LEVEL_CURRENT"
* Add "OTHER" window level, as replacement for "CRAP"
* Continue to honor "CRAP" as a synonym for "OTHER".
* New function $levelctl(), to add/query window levels.
* Window/lastlog levels can now be added at runtime. HUZZAH!

* Add the 'highlight' script which implements the highlight-ignore thingee
* Whack the 'highlight ignore' feature as per discussion on the list.

* Don't do LOCAL_COPY within an infinite loop, leads to stack exahustion.
* Support new signal, SIGUSR2 which throws "system_exception".
* Teach the block commands about "system_exception" so they can be stopped.
* Whack a bunch of unused timers from vars.c. (see UPDATES)
* Sync up config.h, vars.h, and vars.c with each other.
* Add "domains" to timers, server timers, window timer, general timers
* When timers go off, latch back to their domain
* Allow timers to self-cancel if their latched item has gone away
* Add /timer -general to set a general timer.
* Make /timer -win or /timer -serv set a window or serv timer especially.

When changing expiration time in $ignorectl(), schedule a new timer.

* Make //ignore output less visually jarring (change a tab to a space)

* Change "ERROR --" to "INFO --" to not alarm people as much.
* Change a few other warnings to not be so alarming.
* Change new_realloc() to not move ptr if it is big enough to hold new size.
* Fix all the status_* sub-formats to not have any hardcoded size limits.

* Make $getsets() work again.
* Fix alloca() warning for freebsd-current
* Fix warnings about static variables not used
* Fix /set notify_level, which is supposed to cascade to /window notify_level
* Fix /set lastlog_level, same thing.

* Make the BUILT_IN_KEYBINDING macro use unsigned chars.
* Hide (struct Key) inside keys.c, and use (void *) to hold state.
* Make the input line use (unsigned char), not (char), huzzah!
* Make the "othername" ($3 in /on dcc_raw "E") the port number.
* Avoid a NULL deref with "parse_command" keybinding.

* Make dcc connections ($connect, /dcc get, /dcc chat) nonblocking
* /DCC RESUME is totaly broken by this.  Will fix later, maybe ;-)
* Add $startupfile(), which returns the epicrc/ircrc file that was loaded
* Offer unknown ctcp requests through /on ctcp_request before /on ctcp.
* Fix /window level none and other such breakages (adm)

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.

Const correctness madness!

Make 'empty_string' (const char []).  Now we're cooking with gas!

EPIC5-0.0.1!  Huzzah!

* Add malloc_strcat_word_c, add a single word to word list, with "" support
* Convert a bunch of stuff to use malloc_strcat_word_c to honor ""s right.
* GC a bunch of unused code.

Overhaul of malloced string handling functions:
* Convert m_[s]c3cat[_s]() to malloc_strcat_wordlist_c()
* Nix m_e3cat(), m_s3cat(), m_s3cat_s(), m_3cat()

* Comment out all the deprecated functions

Convert m_strdup() to malloc_strdup().

* Add "creation time", "last used time" and "usage counter" features to
  ignore.  This was specifically asked for, but I don't know who asked for
  it (i don't have it written down here), so please forgive me for not
  crediting you with the idea. =)

Fix backporting bug trying to malloc_strcpy() to NULL
when you do $ignorectl(GET <refnum> EXPIRATION).  Reported by hsoc.

Commit 529.
Do final fixup on $ignorectl().

Commit 527
New ignore implementation.  I will document all this stuff tomorrow.
As it stands, I've tested this for several days and all seems well.
Of course let me know if you see any problems.

* 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!

* 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 "{}".

* 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.

Update copyright notices and copyright dates.

No functional changes, just removal of unecessary whitespace at the end
of lines.  From adm.

Thanks to wd for this patch, which:

* Breaks part of figure_out_address() off into figure_out_domain().
* Fixes /ignore and $mask() such that they don't munge the given address
  inappropriately.

I have compared $mask() behaviour with previous versions to confirm that
it works, which would tend to imply that the main guts are all working,
but nevertheless, figure_out_address seems to be particularly delicate so
there may be problems.

* Miscelaneous 3cat updates.
* History expansion copies the history buffer verbatim now.
  * Bugfix:  /!0 would not retrieve the first command entered.
  * Bugfix:  Negative numbers not found would be display the
    incorrect number in the error message.  eg:  /!-4444
* Alterations to remove_trailing_spaces interface.
* $igetrmatches() was defined, but inaccessible.
