Provide an API to query which tiles are currently being synced. This allows the higher levels (TileManager in FlightGear) to safely wait on TerraSync before loading tiles. Doing this exposed some bugs in scheduling tiles to sync by integer lat/lon, related to round-towards-zero with -ve values (western / souther hemispheres). To resolve these, and also reduce spurious syncs, switch to an explicit API for requesting tiles by SGBucket. This keeps TerraSync fully aligned with the TileManager queue, which has many benefits for both high and low visibility situations.
