Subject: [PATCH] Add backward compatiblity code for <termio.h>.

The backward compatibility code for <termio.h> has been removed starting
from GLIBC 2.42. So it starts to fail on some bleeding edge distributions
like openSUSE Tumbleweed. We took back the code removed from the GLIBC
and put it back inside txInput.c.
