Fix bug with history expansion when there is a line with only /'s in it.
Reported and fixed by |Rain|.

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

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()
* Nix m_ec3cat(), m_sc3cat(), m_sc3cat_s(), m_c3cat().
* Convert m_dupchar() to malloc_dupchar().
* Convert m_strndup() to malloc_strndup().
* Make malloc_strcpy/malloc_strcat/malloc_strcat2/malloc_strcat_wordlist macros
* Convert m_2dup() to malloc_strdup2().
* Convert m_3cat() to malloc_strcat2[_c]().
* Convert m_3dup() to malloc_strdup3().
* Convert m_ec3cat() to malloc_strcat2_c()
* Use strlcat_c() in $repeat() instead of strlcpy(). whee!
* Sanity check first arg to $regcomp(), to avoid crashes.
* Don't pass NULL to bsearch(), even if 'nmem' is 0 [$remws()]
* Nix the original malloc_strcpy (supplanted by malloc_strcpy_c)
* Comment out all the deprecated functions

Convert m_strdup() to malloc_strdup().

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.

Okay.  User input is now handled specially, and parse_command() will not
accept incomplete command names anymore.

Another merge.

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

Commit #427
* Add -l<tcl> to the front of $LIBS so -lm can come after it
* Look for SSL stuff in default location before hunting for it in /usr/local.
* Reset $withval after check for perl so --without-perl doesn't --without-tcl
* Make first arg of cvtchar() a (const char *) to silence warning.
* Move 'this_sucks' label to a place where it is legal.
* Make check_val() cope with NaNs and INFs more graciously...
* Fix null deref with /lastlog -c
* Update the input line in set_update(), not the caller
* Do update the input line when redrawing status
* Change make_status() to return a success/failure value.
* Don't clear the "status line wants redraw" flag if redrawing status fails.
* Nuke the now unecessary "in_window_command" global variable.
* Fix bug where <scrollback> + <scrollforward> left you in scrollback mode.
* Force init of Window->lines_held = 0 even though that shouldnt be needed.

Update copyright notices and copyright dates.

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

* 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.

Commit #41 -- Typo (my fault) from commit #40 broke history.

Commit #40 -- Robohak's fixes for history:
* Remove worthless support for adding lines to history that contain
	embedded newlines
* Don't permit the last item in the history buffer to be added again
	to the history; just silently punt it.
