netbsd: Support curses libraries without ncurses mouse support

Browse Source 
This adds a configure check for the ncurses getmouse() function
and disables mouse-related code paths when mouse support is
not present in the curses library.

This is necessary for stable versions of NetBSD's libcurses, the
development version has stub mouse functions for compatibility
with ncurses.
