maple_tree: Dense node support & nulls in tree.

Support dense node types.  The reduces the space required for sequential
indexes a lot.
Splitting now decides between usign the parent type and the dense node
type for left/right independently.
Fixes had to be made to pivot lookups.
A few static inline additions to speed things up.
