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 commit reverts parts of 111fc5e, which originally was intended to
add support for custom key bindings at pos 0, or more specifically, to
be able to change the behavior of Ctrl-D. However this completely broke
compatibility with the original EOF behavior.

The word 'new' is a reserved keyword in C++ and C#, replacing it
with something else is one step further to making it possible to
build editline with a C++ compiler.

This commit adds a new global variable 'el_no_hist' which can be used
to disable auto-save of history as well as access to history using prev
and next keybindings (up/down arrows).

Handle tcgetattr(), tcsetattr() and ioctl() by wrapping them in
a retry-loop and restarting them when receiving EINTR.
Should fix problem with sporadic error messages on the console
like this one:
'Failed tcsetattr: Interrupted system call'

The two functions el_bind_key() and el_bind_key_in_metamap() should
not print status message on stderr, but rather return the status of
the key binding operation.

When adding support for rl_reset_termial() the tty_info() code was also
refactored. This however led to the introduction of a bug that caused
tty_cols to be set to zero. This in turn caused c_possible() to fail
with SIGFPE in el_print_columns().
Regression was introduced in 1c89c9886c
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.
