Introduce RelResult rather than Vec<Vec<TypedValue>>. (#639) r=nalexander
* Pre: clean up core/src/lib.rs.
* Pre: use indexmap 1.0 in db and query-projector.
* Change rel results to be a RelResult instance, not a Vec<Vec<TypedValue>>.

This avoids memory fragmentation and improves locality by using a single
heap-allocated vector for all bindings, rather than a separate
heap-allocated vector for each row.

We hide this abstraction behind the `RelResult` type, which tracks the
stride length (width) of each row.

* Don't allocate temporary vectors when projecting RelResults.
