Use src/contrib/ncurses, v5.0.990821 prerelease.

This isn't quite finished yet, there are still some unresolved problems
with ospeed and the sgtty.h (non-posix) terminal interface.  Mostly
this only causes problems with src/games.

The other tools and libraries (libform,libpanel,libmenu) will come
shortly but are seperate.

Beware, there be dragons here!  (The build will be broken for a short
while)
