Revamped input line a little. Added indicator for text scrolled off the left
of our input line.

Fix all the compile warnings that I let go way too long.

* Add a new internal function prepare_display2() a reduced version of p_d().
* Add a new internal function fix_string_width(), the guts of $fix_string()
* Fix /set indent to use prepare_display2(). Now you can use ^C codes. yay!
* Fix fd leak if fork() fails for /exec.
* Fix window toplines so they extend the width of the screen like statusbars.

* Add /lastlog -rewrite (see UPDATES)
* Add /set lastlog_rewrite as a special favor for larne.

Move some functions out of input.c to places where they make more sense.
This makes it easier for me to re-org input.c.

Fix another minor bug.

* Stage 2 -- start eliminating "optimizations", use update_input() for redraw

Stage 1 in a major overhaul of the input line handling code.
Caution -- road may be slippery when wet.  Many more changes to come.

Add code to do threaded stdout (from larne)

* Add /window indent, allowing you to overrule /set indent per-window basis.
* Make window breaking use /window indent
* But /set indent still overrules any /window indent's you've set. :/

* Handle \f as a special case in new_normalize_string for the status bar.
* Do some re-org in screen.c, screen.h
* Roll window_disp() into its only caller, add_to_window().
* Change create_new_screen() into a void function

* Change all the builtin functions to use new_normalize_string().
* Change the input prompt to use new_normalize_string().
* Add /set mangle_display. HUZZAH!
* Change the display stuff to new_normalize_string() and /set mangle_display
* Whack the now unused normalize_string(). HUZZAH! HUZZAH! HUZZAH!
* Change the seperator of the mangler-type-parser to be spaces and not commas.
* Start keeping a monotonically increasing refnum for all lastlog items
* Change add_to_lastlog() to return the lastlog refnum
* Change add_to[_window]_scrollback]() to take the lastlog refnum
* Cross-link scrollback items with the corresponding lastlog refnum.
* Save scrollback/hold position across scrollback rebuilds
* This means rebuilding doesn't affect scrollback/hold users! HUZZAH!
* Whack the now unnecessary /window auto_scrollback (mis)feature.
* Don't unconditionally unclear after rebuild, if everything still fits.

For a little while at least, $stripcrap() acts differently from the
/set mangle_* type stuff.  This is a work in progress.  Please be patient =)

* Nix the last vestiges of the unsupported ROM_CHAR feature.
* Nix some now unused function decls in screen.h
* Add new_normalize_line, which is a unified normalizer/mangler (*gulp*)
* Cut over $stripcrap() to use new_normalize_line (*double gulp*)
* Rename "ANSI" mangle type to "NORMALIZE", but still accept "ANSI"
* Nix the gxlate table, and change ^T from State 4 to State 6 character.

* Fix $stripc() to be a clone of $stripcrap(), just to strip colors
* Nix the now unused strcpy_nocolorcodes().
* Fix up read_color_seq() to return an offset, not ptr, a la skip_ctl_c_seq().
* Fix mangle_line() to use read_color_seq instead of skip_ctl_c_seq
* Nix the now unused skip_ctl_c_seq(). Only one thing now reads ^C's! HUZZAH.
* Rename skip_esc_seq() to read_esc_seq() just because.
* Begin moving logic|display_attributes towards a change model system
* Begin a radical change on how characters are given "state" (see source)
* Basically 8 bit chars (except c1 chars) are treated as "always printable" now
* Mangle a few other callers to logic_attributes, i'm sure these are b0rked.

* Remove some now unused xdebugs, fix compile warnings.

* Move some defines from comands.h to where they belong
* Add and remove func decls in header files as necessary.
* Add /wait =<fd> which returns when a nonblocking dcc connection finishes
* Make all keybinding funcs/decls use the BUILT_IN_KEYBINDING macro.
* 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.

GC a bunch of useless cruft and stuff.

* Make new_open[_for_write] take a callback function, stash it in io_rec.
* Add handle_filedescs() which takes select() results and calls callbacks
* Make io() call handle_filedescs() instead of the four callback functions.
* This is the first stage of an extendable callback event looper!  huzzah!

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

* 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!

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

* Make as much as possible use refnums as params and not from_server.
* And a lot of other stuff...

Ach.  Here goes nothing.
Major commit which does many things, but the most prominent of which
is the final integration of the scrollback buffer with the hold buffer.
This fixes several annoying "features" and introduces a small truckload
of new features which have been requested recently.  Please see the
KNOWNBUGS or UPDATES file for more info, since I don't want this message
to be ridiculously long.

New keybindings system coming through.  Details can be found in doc/keys
and in a few other places. :)

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.

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!
