draw the buttonbar in its own viewport. It always uses the sysfont and is drawn on the bottom.
Callers need to remeber to fiddle with their viewports to not be overwritten by the bar. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17651 a1c6a512-1295-4272-9138-f99709370657

- Rewrote a lot of code to avoid global vars and make it accept eventually
more that 3 buttons on the bar (just the prototype of gui_buttonbar_set
and the constant BUTTONBAR_MAX_BUTTONS to modify)
+2008 Jonathan Gordon
+ - redone to use viewports, items will NOT scroll in their vp.
+ Bar is always drawn at the bottom of the screen. This may be changed later.
+ Callers need to remember to adjust their viewports to not be overwitten
