pkgbase: move ncurses into its own package

[kevans]

Summary

Pushing ncurses into clibs adds extra upgrade risk to a package that
otherwise consists of integral libs with non-trivial interdependencies.

Adding it to -runtime was considered, but the move was historically
motivated to some extent by allowing a much smaller set of base libs to
be installed for smaller VM images that don't really need all of the
runtime package.

This also fixes the ncurses build to ensure that libmenuw is grouped
with the rest of the ncurses libraries, which doesn't seem to have been
an intentional omission.

please add a copyright header to ncurses-all.ucl.

we might also want to consider using LIB_PACKAGE to put the libraries in a separate -lib package. i'm not sure if that's really needed though, the utilities are quite small.

it might be worth mentioning that ncurses implements SVI (System V) curses, since traditional BSD curses didn't.

perhaps also mention the terminfo-db port, which provides the proper terminfo database for ncurses to replace the somewhat sparse /etc/termcap in base.

Add licensw from ncurses for description theft, add more words
