Introduce traversalValue for SP-GiST scan During scan sometimes it would be very helpful to know some information about parent node or all ancestor nodes. Right now reconstructedValue could be used but it's not a right usage of it (range opclass uses that).
traversalValue is arbitrary piece of memory in separate MemoryContext while reconstructedVale should have the same type as indexed column. Subsequent patches for range opclass and quad4d tree will use it.
