top: extend 'Ctrl' bottom window for 'memu' selections <=== port od newlib 659590b0

______________________________ original newlib message

This commit adds a prototype for a potential extension
of that tabbed bottom window capability. It introduces
a 'menu' which then provides for users' selections. It
does not actually do anything meaningful and will only
be enabled with the new #define called 'BOT_PICK_YES'.

[ since it's just a proof of concept, no attempt has ]
[ been made to add the usual NLS translation support ]
