initial empty check-in
Add a curses based menu compiler system.  (Used by the new system install
program sysinst.)
Import a simple message system with 'compiled' messages.  Used by
the net system install program.
Import of sysinst.  Not quite ready, but other ports want access for
parallel development.  i386 version about 90% complete.  pc532 version
just started, other architectures later in coordination with portmasters.

This is a curses based, menu driven installation program.

Better error checking is needed.
