Create new enum edge_pos with TOP_EDGE, BOTTOM_EDGE, LEFT_EDGE,
RIGHT_EDGE; subsume TOP_BORDER, TOP_GUTTER, enum toolbar_pos,
enum gutter_pos, etc.
Create EDGE_POS_LOOP, subsuming GUTTER_POS_LOOP.
Create NUM_EDGES, use in many places instead of hardcoded '4'.
Instead of top_toolbar_was_visible, bottom_toolbar_was_visible,
etc. make an array toolbar_was_visible[NUM_EDGES]. This increases
the frame size by 15 bytes or so (could be 3 if we use Boolbytes)
but hardly seems w to matter -- frames are heavy weight objects
anyway. Same with top_gutter_was_visible, etc.
Remove duplicated SET_TOOLBAR_WAS_VISIBLE_FLAG and put defn in
one place (toolbar.h).
