Subject: [PATCH] build-sys: support ncursesw without headers in ncursesw/
directory
Let's check always for alone ncurses.h and term.h if the preferred
variant with ncursesw/ subdirectory is not available.
The patch also minimize number of HAVE_...NCURSES_H macros in
config.h. We don't need to check for ncurses.h if ncurses/ncurses.h is
available.
