* Remove tiles outside processing range. Useful when new content profile map
has different bounds.
* Remove ignored tiles. For a case when content profile maps have intersection
but there is no more data for navmesh.
* Remove older tiles at the same worldspace position. If navmesh tile data has
changed with new content, the old ones unlikely to be used.
* Vacuum the database when there are modifications. SQLite leaves empty pages
in the file on database modification. Vacuum cleans up unused pages reducing
the file size.
If object is too big iteration over all tiles covering it can take too much
time. Limit bounds to a square around a player position to cover only tiles
that will be present in navmesh based on max tiles number option.
Each object is associated with a set of tiles its present in. Culling can
reduce this set but it has to be update when bounds change position. Do this
in TileCachedRecastMeshManager::setBounds updating the set and adding/removing
objects to the corresponding CachedRecastMeshManagers.

Perform all request to db in a single thread to avoid blocking navmesh
generator threads due to slow write operations.
Write to db navmesh for all changes except update as it done for memory cache.
Batch multiple db operations into a single transaction to speed up writing by
not executing fsync after each insert/update query. All reads are performed in
the same transaction so they see uncommited data.

OscillatingRecastMeshObject::update should be called with tile bounds in real
coordinates not in navmesh. But proper scaling was done only in
RecastMeshManager::getMesh and RecastMeshManager::updateObject used tile bounds
in navmesh coordinates.
Add a new function to create tile bounds with proper scaling and pass correct
value into RecastMeshManager constructor through CachedRecastMeshManager
constuctor from TileCachedRecastMeshManager member functions.
