Subject: c3270: Fix SIGILL with screen_changed variable
References: bsc#1104013
Patch-mainline: 3.3.14alpha1

The screen_changed variable is defined as a Boolean (char) in
c3270-3.3/ctlr.c but it is used with "extern int" in other files.
This causes c3270 to crash with "Illegal instruction" when calling
it without any parameters on s390x.
So use "extern Boolean" instead as a minimal fix. The wc3270 client
is affected as well but not relevant for SLES.

This is based on svn://svn.code.sf.net/p/x3270/x3270/trunk@1112:
