Teodor Sigaev ccd6eb49a4 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.
