syncbase: SyncQL: Support key expression operators: <,<=,>,>=,<>.

Rather than approximating key ranges (and, therefore, sometimes
iterating over more keys than necessary), this change computes
precise key ranges.  At the same time, operators in key
expressions can now include <, <=, >, >= and <> (in addition to =
and like that were already supported).
