UTF-8 support for call.

Patch by Cathryn Mataga.

1.  Now supports UTF8 or IBM850 as the encoding style over AX25.
1a.  Attention was paid to make sure that wide characters worked
with East Asian fonts.
2.  Now the screen can be resized.
correctly.   The program no longer crashes when it is resized.
3.  Added a scrollback buffer.  Use the up and down arrow keys
or the page up/page down keys to scroll through history.
After the screen begins scrolling, press 'up arrow' to view
history.
4.  Many visual quirks have been fixed.

This version is now dependent on iconv and wide character
versions of ncurses, which I think should be everywhere these
days.

 .BI "\-W"
 Wait for remote disconnect even if stdin is closed. Normaly, "echo q | @@@call@@@ ax0 db0fhn" closes immediately after "echo q" terminates; thus we never see the greeting from db0fhn. With the -W option, @@@call@@@ waits until the ax25-connection is disconnected (i.e. db0fhn disconnects after "q" command). Very useful for scripting. You might like to combine it with the -T option.
