* Eliminate the third argument to expand_alias(), the statement spanner.
* Rename parse_line() to parse_block() to better reflect its duties.
* Make parse_block() static.  Everything needs to call runcmds() now.
* Eliminate the local-stack-creating feature of parse_block(), callers do this.
* Rename 'line' to 'stmt' in parse_statement().
* Sort of forget to re-implement /set cmdchars.  The / is the cmdchar.
* Try to optimize parse_statement() and next_statement() some.

* Fix several bogons in add_to_log, found by ce.

* Nix some func decls in windows.h that don't exist any more
* Add message_setall(), lets you save to_window on the message_from stack.
* Replace users of message_to() with message_setall().
* Replace direct users of to_window with message_setall(). yay!
* /XECHO got rewritten as part of this.  See UPDATES
* Fix various compiler warnings.

* Include <stddef.h> if we can, for no particular reason...
* Nix now unused mangle_line(). yay!
* Use (intptr_t) instead of (intmax_t) to treat pointers as integers...
* Try to handle failures from the dns helpers with more grace.

* Convert the other users of mangle_line() to new_normalize_string (*gulp!*)

* Fix compile error for #define UNAME_HACK
* Fix crash when you do $open(/file/doesnt/exist R)
* Add an /on 338 default handler.
* Fix integer underflow with log file refnums
* Rename STATUS_USER0 to STATUS_USER for backwards compat. oops!
* Whack BRACE_LOAD_HACK, it's been unsupported for a while.  PF loader rules!
* Don't allow /botmode if #define NO_BOTS
* Fix DCC connections instantly "timing out"? (Check on this)
* Whack FLOATING_POINT_SUPPORT and depend only on /set floating_point_math

Add $logctl(CURRENT) which returns the current operative logfile.
For zlonix.

* 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)

* 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.

GC a bunch of useless cruft and stuff.

* - 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.

Another merge.

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

* Use server_list_size() and not number_of_servers outside of server.c
* Use NOSERV and not -1 for "no server"
* Use (Timeval) and not (struct timeval)
* Fix (get|set)_server_sent_*() et al to take server refnum.
* Use parse_server_index() and not my_atol() to parse server refnums
* re-indent quotecmd
* Rename is_server_connected() to is_server_registered
* Make /quote work as long as server is open (not registered)
* Use send_to_aserver() when it can avoid setting from_server unecessarily
* Change sent_to_server and clear_sent_to_server to (set|get)server_sent().
* Change doing_* to get_server_doing_*.
* Use (unsigned short) and not (u_short)
* Use (unsigned long) and not (u_long)
* Make output_reject_ctcp() take a refnum
* Lock a dcc while we are connecting it, just in case. ;-)
* Fix /dcc send -p <port>
* Store protocol enforcements as (get|set)_server_protocol_state().
* Use (Stat) and not (struct stat)
* Rewrite $timerctl() so it works like $logctl()
* Rename is_server_connected() to is_server_registered()
* Fix an off-by-one error with /FOR ... IN ...
* Keep track of both readable and writable fd's with newio stuff.
* Convert server_list to an array of pointers
* When user /server -delete's, leave a gap, don't change refnums around.
* Nix code that handles deleting server refnums.
* New function, new_open_for_writing(), for when we do nonblocking connects.
* 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.
* Make everything that uses server_list[] use get_server() instead.
* Make everything capable of dealing with "gaps" in server_list[].
* Use a bunch of macros, to handle with getting and setting server attrs.
* Make as much as possible use refnums as params and not from_server.
* And a lot of other stuff...

* Added functions $asciiq() $chrq() $exec() $timerctl() $tcl() $winline()
  and $floodinfo().
* Altered the two argument version of $read() to ctcp quote the strings it
  returns.
* Added sets FLOOD_RATE_PER and FLOOD_MASKUSER.
* Altered the "accept" mode of the dcc_raw and dcc_connect hooks to refer
  to the local port instead of the remote port.
* Added a "-closein %proc" switch to /exec.
* Altered the arg list mode of /alias to use extractw instead of next_arg.
* Added the documented "words" argument to the above.
* Tuned autoget, mudirc, tabkey.ce and commandqueues.
* Altered /pretend to not chop the string.
* Set about rewriting the flood detection and then decided that it's better
  off being a script.
* Moved the function macros to their own file (functions.h) and replaced
  all the copies that are strewn throughout the source with an #include.
  The exception is array.c which broke when I tried it.
* Moved the ctcp enquoting/dequoting functions to ircaux.c.
* Added some command/function ordering checks to funcs/regress, and a check
  for all the functions that are undocumented.
* Rewrote function chanmodetype() so that it doesn't have all those flakey
  buffering things.  Hopefully it's readable now.  The significant change
  is that if a mode character appears twice in CHANMODES, the first one is
  returned instead of the last.
* Added EPIC::call() in the perl routines and an equivalent under tcl.
  this is designed to call a $function() directly, but it isn't really that
  fast, so I might rip them out again.
* The /wait internals used to store a few other settings, which were taken
  out, so I put them back.
* Fixed a few problems with normalize_filename() around the place.
* Fixed a bug with /timer in which it would never show the timers after a
  callback.

* Change expand_twiddle(), path_search() to take results as params, int retval
* Add normalize_filename(), to do job expand_twiddle() used to do.
* Add isdir(), just because
* Change /CD, /LOAD, /SAVE, /DCC SEND, /DCC GET, to use normalize_filename.
* Change /DCC RESUME, $open(), $which(), $unlink() to use normalize_filename.
* Change $rename(), $rmdir(), $fexist(), $fsize() to use normalize_filename.
* Change $glob(), $globi(), $mkdir(), $chmod() to use normalize_filename.
* Change $ftime(), $randread(), and uzfopen() to use normalize_filename.
* Change /LOG, /SET LOGFILE, servers file to use normalize_filename.
* Fix /LOG so maximum number of targets per log is a compile time #define.
* Revamp expand_twiddle() and uzfopen().
* Fix uzfopen() to look for 'bunzip2' in addition to 'bunzip'.
* Fix bug with /QUEUE -delete
* Remove unused variable in window_scroll().

Commit the current /LOG command and $logctl() function.
These are nowhere near ready to be used at this point.  I am still working
on them, but this is good enough if you want to take a look at it.

THINGS WILL STILL CHANGE FROM THIS POINT.  DON'T BE USING THIS YET.

* Fix expand_twiddle to take a (const char *)
* Fix do_log and set_log_file to take a (const char *)
* Remove a couple of no-ops in keys.c
* Revamp do_log into two parts; open_log and close_log; do_log now a wrapper.
* Fix a string that had a newline in it. spotted by Szabolcs Rumi.

Update copyright notices and copyright dates.

Due to the way the new attribute parser works, mangle_line needs a destination
buffer that is at least eleven times as large as the original string.  Change
all uses of mangle_line to pass in 11 times as much as necessary.  This avoids
uneccesary truncation of input lines with excessive attribute changes in them.

Commit #47
* /window server resets the "reconnect attempt" counter ala /server
* /for i in <pattern> {...} now reserved, and emits an error.
* "make depend" done again.
* "my_next_expr" revamped, extra argument added
* "next_expr_with_type" like "next_expr" but first char is "type".
* The /for i in (list) and /for i from x to y commands now use the
  above cruft.
* This is epic4-0.9.16-10
* "break_args" now uses "next_expr_with_type"
* "do_log" should use localtime(3) and not gmtime(3), duh.
* "clear_reconnect_counts" is now an extern function from server.c
