Prefer passing arguments to declaring external global variables. The
only remaining usage of extern is for config.h variables which are
needed in st.c instead of x.c (where it is now included).

This also allows us to remove the crlf field from the Key struct, since
the only difference it made was converting "\r" to "\r\n" (which is now
done automatically in ttywrite). In addition, MODE_CRLF is no longer
referenced from x.c.

config.h includes references to KeySyms and other X stuff. Until we
come up with a cleaner way to separate configuration, it is simpler
(leads to more code removal) to have this here.

Modifiers and keysyms are specific to X, and the functions match and
kmap are only used in x.c. Needed to global-ize the key arrays and
lengths from config.h (for now).

CTRL+SHIFT is an impossible combination in the terminal world
(0x20 | x & 0x1F), so it is perfect to be used for internals
shortcuts of terminals, and being a double combination
reduces the prossibility of having comflicts.
When using st with screen, I've bound next, prev, new screen to
combinations like Ctrl-Alt-Right,Left,Down; xterm and (u)rxvt work fine
when this combination of modifiers is pressed, st does not seem to
transport all of them; a single modifier key is fine (e.g. Ctrl-Up,
Alt-Down etc., but combinations are not). While I'm not terribly
familiar with this, I have tried to hack config.h in a more or less
systematic way to generate the expected sequences.
The default config specifies BackSpace as "\177". The default behavior
should persist across modifier keys, commonly Mod1 (Alt or Meta) which
is widely used to delete a word on readline and text editors, notably
Emacs.
This will make Alt+BackSpace behaves as expected, i.e. sends "\033\177"
instead of "\033\010" as previous default behavior.

This fix is needed to use dual-width fonts, which have double-width
glyphs (e.g. CJK unified ideographs).

This practice proved itself in sbase, ubase and a couple of other
projects.
Also remove the True and False defined in X11 and FcTrue and FcFalse
defined in Fontconfig.

Not always is desirable to create a pseudo terminal, and some times
we want to open a terminal emulator over a tty line. With this new
patch is possible to do someting like:
$ st -l /dev/ttyS0 115200
Without this option was needed to launch another terminal emulator
over st (for example minicom, picocom, cu, ...).
Thanks to Alex Pilon <alp@alexpilon.ca>!
Now there is a distinction between the primary and clipboard selection. With
Mod + Shift + c/v the clipboard is handled. The old Insert behavious does
reside.
St runs an interactive shell and not a login shell, and it means
that profile is not loaded. The default terminal configuration
in some system is not the correct for st, but since profile is
not loaded there is no way of getting a script configures the
correct values.
St doesn't update the utmp files, this is the job of another
suckless tool, utmp. Utmp also opens a login shell (it is the
logical behaviour when you create a new user record) it is a
good option execute utmp and then get a correct input in
utmp, wtmp and lastlog file, and execute the content of the
profile.
DEL key has to generate the sequence ^[P in application mode,
because such sequence means delete current character. It implies
that the character sent in keypad mode must be ^? (DEL character).
VT102ID is the sequence that the terminal returns when it is inquired
to identify itself. This value should be configurable in the same
way that another st parameters.
