add various type changes to avoid problems on systems where int and

ssize_t are different sizes.  Make filestruct->lineno a ssize_t (so that
we can avoid negative line numbers at the "Go To Line" prompt),
current_y a ssize_t (in order to hold the maximum difference between two
filestruct->lineno's), totlines a size_t, and change related variables
to match
