* Add /on signal (pegasus)
* Fix /set indent if /set continued_line contains ^C stuff (pegasus)

This should NOT have been commited.  Back it out.

Miscelaneous fixes and features as per UPDATES and KNOWNBUGS.

* Add /SET STATUS_NOSWAP
* Fix #define DEBUG_EXTRACTW_DEBUG/LASTLOG
* Add -o and -O command line options to turn off IEXTEN termio() options
* Add /WINDOW SWAPPABLE (defaults to on)
* Add %{1}W status expando, expands to /SET STATUS_NOSWAP if SWAPPABLE OFF
* Don't allow windows to be swapped in or out if SWAPPABLE OFF
* Don't allow windows to be shown or hidden if SWAPPABLE OFF
* Do allow windows to be swapped in with WINDOW KILL even if SWAPPABLE OFF
* Add $windowctl(GET <refnum> SWAPPABLE)

Implement "privleged yells" which allow syou to do /set debug 7 at the
same time as /set output_rewrite.  Yea~!

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.

Commit #555:
* Add #define MINIMUM_CLOCK_INTERVAL and MINIMUM_MAIL_INTERVAL in config.h
* Add #define DEFAULT_CLOCK_INTERVAL and DEFAULT_MAIL_INTERVAL in config.h
* Add reset_system_timers(), do_update_clock(), and set_cpu_saver_after()
* Add time_to_next_interval(), general form of time_to_next_minute().
* Add get_clock() and reset_clock() to replace update_clock().
* Make remove_timer() an extern function so i can delete timers. ;-)
* Add /SET CLOCK_INTERVAL and /SET MAIL_INTERVAL
* Make $T use the static clock.
* Reorganize system timers 1 and 2 into four timers:
* - CPU SAVER timer, checks for idleness, to turn on cpu saver
* - CLOCK timer, updates the status bar clock periodically
* - MAIL timer, checks for new mail periodically
* - NOTIFY timer, checks for others on irc periodically
* The above three honor "cpu saver" mode.
* Nix the old "do_every_minute" timer.
* Reorganize the clock generation stuff into "reset_*_clock" functions
* Generate the clock statically; only update it from the CLOCK timer
* Add reset_system_timers() which regenerates all four system timers.
* Don't set system timers in main, call reset_system_timers() instead.
* Don't enforce "notify interval" in do_notify(), handle that in NOTIFY timer.
* Comment stuff in words.c

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!

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.

Another merge.

* Make /LOAD locate and open file arguments; and a generic handler
* Create loader_which() which a /LOAD handler for /WHICH command
* The standard loader is now called "loader_std"
* Add an empty next-generation loader called "loader_pf"
* Add "loader" info to "load_level" data; It's $2 in $loadinfo().
* /LOAD now takes -std and -pf arguments to specify which loader you want.

* $dccctl() changes as per UPDATES.
* Misc bug fixes as per KNOWNBUGS.

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

Commit 436
This commit is deceptive because it is huge in scope but can be explained
pretty simply.

* Change new_open() to deregister fd as "writable"
* Renovate the notify stuff to take refnums and not just use from_server.
* Renovate /WHO, /ISON, /USERHOST to take refnums and not just use from_server.

Add GAILIB, a bsd licensed getaddrinfo/getnameinfo implementation for
ipv4 only systems.  This was lifted from ruby, who lifted it from WIDE.
Add #ifdef's as necessary to compile on non-ipv6 systems.

Huge major commit #1 in the great IPv6 support addition...
Rather than include all of the changes here, read KNOWNBUGS changes.

Next round of in_addr/u_short -> sockaddr_in conversions, along with some
other minor details.  As far as i know, this shouldn't break anything,
but I don't promise that.  Save your old binary first!
If anything is really bad, let me know.  I'll fix it ASAP.

Bulk commit:
1) Fix typos in KNOWNBUGS
2) Flesh out the things in UPDATES that need documenting
3) Add target_file_write() to files.[ch] for send_text()'s use.
4) Create "reg.h", to hold protos for reg.c
5) Add some missing protos.
6) If /redirect'ing to 0 or to @<fd>, don't output to the screen.
7) Messages sent to target 0 are dropped (/redirect 0 now actually sends
   to target 0, and epic drops it.)  You can /query 0 now if you want.
8) Messages sent to @NUMBER get sent to the NUMBER file, where NUMBER is
   returned by $open().  For example, to paste stuff to log but not to screen:
        @fd = open(FILE w)
        query @$fd
        <paste some stuff>
        query
        @close($fd)
   or
        @fd = open(FILE w)
        redirect @$fd lastlog foo
        @close($fd)
9) Add a function to reg.c to compile a pattern into a regex -- experimental.
10) Fix some compile warnings regarding ssl.

Expose "commit_id" to the rest of epic.
Add $info(i) which returns "commit_id" to the user.
I should have done this eons ago.

~/.epicrc support!  kb should like this.

This is the new highlight/attribute renderer.  It is a "true renderer"
because it actually renders things to look like what you say.  No longer
does turning on some attributes (color) turn others off, nor does turning
some off (bold) turn others off.  Some things may break with this, please
let me know, or feel free to pitch in and fix them.

Zinx will be happy to know that i did NOT use the epic5 "prepare_display"
routine because he was right, i did totaly break it.  I used the epic4
prepare_display function but just made it aware of the new attribute stuff.

The beginning of the migration away from 'time_t's towards 'struct timeval's.
This first round of support is very rough and may have some issues, which
I will be happy to fix (or you can fix them yourself if you want), but it is
more proof-of-concept work for now.  I don't expect that I will migrate
*everything* to struct timeval, just the important stuff.  I have not made
any serious attempt to optimize this yet and please don't jump the gun and
start optimizing this until I've got the bugs settled out.  Thanks. =)

Oh yes, I almost forgot the good part -- /timer now has highly accurate
sub-second timer resolution.  This means you can do /timer 0.82 echo test
and it will go off in exactly 0.82 seconds.  No more "approximate" timers!

The traditional restrictions about timer execution (timers do not go off
while another timer is executing, and while you are /wait'ing) still apply.
