* Move "term.h" out of the way so we can #include <term.h> (mv'd to termx.h)
* This makes it possible to avoid empty decls for tparm()
* Which is supposed to fix the build for larne on who-only-knows-what.
* Rename tparm() to my_tparm().
* Do a make depend since i changed the name of a header file. ugh.
* Change the name of (struct term) to (struct my_term) for freebsd sake. ugh.

* Fix two 64-bit pointer errors (one in dcc.c, and one in who.c)
* Fix refresh_a_screen() to not pass NULL to recalculate_windows().
	(reported by cshepherd, thanks!)

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

* 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.

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...

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.

Update copyright notices and copyright dates.

Fix "make installscript"
Fix /lastlog so that the header/footer use "numeric_banner" instead of
	fetching /SET BANNER so that /SET BANNER_EXPAND is honored.
This requires that 'lastlog.c' include 'numbers.h'
This requires a 'make depend'
Minor nitpick in output.c

* Enhanced flood checking to keep records based on userhost rather than
  nick.  Not designed to catch clones but to make it harder to avoid.
* Flood checking keeps its time in microseconds now, which _may_ make it
  a little hyperactive on occasions.
* Small re-arrangement to find_array_item() to make it slightly faster.
* Terminology fix in /alias /s.
* Added $regmatches() which works exactly like $regexec, but returns pairs
  of numbers which can be applied to $mid() to extract the matched strings
  and substrings from the original string.  It also takes a new second
  argument indicating the maximum number of subexpressions to return.
* New -file option to /lastlog.  If given, all output will be written to
  the file rather than the screen.  file_put_it() may be questionable.
* $channel() will return "h" in the op field if the user is a half-op.

Resizable wserv support!  No, really!  Backported from epic5.
I have to go through term.c again and make sure there are no unintended
casualties of the merge.  We should also start testing the resize handlers
to make sure they're happy.  I don't promise they'll all work first time,
but this is a good place to start!
