Introduce rb_insert_augmented(), which is a version of rb_insert_color()
with an added callback on tree rotations. This can be used for insertion
into an augmented tree: the handcoded search phase must be updated to
maintain the augmented information on insertion, and then the rbtree
coloring/rebalancing algorithms keep it up to date.

rb_insert_color() is now a special case of rb_insert_augmented() with
a do-nothing callback. I used inlining to optimize out the callback,
with the intent that this would generate the same code as previously
for rb_insert_augmented(). This didn't fully work, as my compiler output
is now *smaller* than before for that function. Speed wise, they seem
comparable though.

The second version of patch 5/6 takes care of my
concerns about this patch.
