Add a way to cleanly handle terminfo.db file used by devel/ncurses

This database contains compiled terminfo entries and is merged from
a large part which comes with ncurses themselves and compiled
.terminfo files installed by other ports (currently only rxvt-unicode
and jfbterm)

- Now the database is always kept up to date, regardless of port
  installation order (both ncurses installed before .terminfo files
  and the other way around work as expected)
- All affected ports now support clean deinstallation and do not
  produce stage-qa errors
- Affected ports are simplified, as they now only need to define
  USES=terminfo
- rxvt-unicode no longer pulls in ncurses: the dependency is not
  really needed for anything beside updating it's own database
- The patch contains Q/A test to check whether a port needs, or
  needs not USES=terminfo
