We want Ctrl-C to work as in Bash, so let's just catch SIGINT (and do
nothing). Also, the default Ctrl-D handler does what we want, i.e.
exit the CLI when we're on an empty line.

This patch adds support for `--disable-eof` and `--disable-sigint` to
the Editline configure script. With either of these two switches the
`tty_special()` function bypasses the special TTY checks making it
possible to bind Ctrl-C and Ctrl-D to custom callbacks. This can be
useful if you want to emulate a Cisco style CLI rather than traditional
UNIX.
The user can of course also redefine the VINTR and VEOF special terminal
control characters, but these configure script switches may be easier to
use for some.
Also, the CLI example has been updated to bind Ctrl-D, Ctrl-C and Ctrl-Z
for testing purposes.

This changeset refactors el_bind_key_in_metamap() into two functions,
adding el_bind_key(), to provide the ability for the user to bind keys
in both the regular and the meta-key maps.
Several useful, but previously internal, functions have been made global to
facilitate the example code mentioned above. These are likely useful to the
user of this library as well:
el_print_columns() - Display words in columns across a tty_cols wide screen.
el_ring_bell() - Can be used as default key binding function.
el_find_word() - Returns a copy of the word at rl_point.
Instead merge afd8b4de9dca8ec6afc3 from http://github.com/heimdal/heimdal.git project.
This lets rl_complete() and rl_list_possib() become wrapper functions calling a set of
function pointers, set using rl_set_complete_func() and rl_set_list_possib_funct().
Each wrapper has a fallback to do filename completion, which in turn can be disabled
by leaving out --enable-default-complete from the configure line.
This change, admittedly quite intrusive for a library, is a better implementation in
many ways. For one it is much more readable, but it also enables further adoption of
other editline forks as well as a simpler implementation of GNU Readline function
pointers rl_completion_entry_function and rl_attempted_completion_function at a later
stage.
My apologies to everyone for whom this change breaks backwards compatibility. For
help on converting your code, please see examples/cli.c.
Remove all old $Id:$ and similar constructs, they don't provide any
additional benefit anymore.
Add configure options for toggling terminal bell and toying with
SIGSTOP using Ctrl-Z. Rename config option for ANSI keys to get
a consistent namespace.
Also did some work on ANSI-fication of function definitions, lot's
of that was still lingering around.
rl_complete() and rl_list_possib(). Simply leave out complete.o from
the default build and in all programs require these two functions to
be supplied.
A better alternative would be to use function pointers and check those
for NULL in the running code. With this code, and no completion handler
the editline code will die.
