scroll-bar-foreground and scroll-bar-background parameters on
ttys.

(mouse-drag-frame-move): On ttys call
'mouse-position-in-root-frame' to get position of child frame to
resize or drag.

child frame decorations as if they happened on the internal border
to find out whether a user wants to drag or resize a child frame.
* src/frame.c (frame_internal_border_part): Define for ttys too.
(Fmouse_position_in_root_frame): New function.
* src/frame.h (internal_border_part): Define for ttys too.

position on a tty child frame's decoration.

as belonging to that child frame (and not to its root).

* src/term.c (Ftty_frame_at):
* src/menu.c (syms_of_menu) :
