Benoît Knecht 1e1b2e163d Make interval overlap comparisons more explicit 
Blocks are half-open intervals [a, b), while all other intervals
(chunks, head, ...) are closed intervals [a, b].

Make that distinction explicit by defining `OverlapsClosedInterval()`
methods for blocks and chunks, and using them in place of the more
generic `intervalOverlap()` function.

This change also fixes `db.Querier()` and `db.Delete()`, which could
previously return one extraneous block at the end of the specified
interval.
