* 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.
To construct serializer from given entities:
* Data source/destination - any value that has to be serialized/deserialized,
usually already existing type.
* Format - functional object to define high level serialization logic to
define specific format and data schema. Like order of fields, allocation.
* Visitor - functional object to define low level serialization logic to
operator on given data part.
* BinaryWriter - copies given value into provided buffer.
* BinaryReader - copies value into given destination from provided buffer.
* SizeAccumulator - calculates required buffer size for given data.
CID 332936 (#1 of 1): Result is not floating-point (UNINTENDED_INTEGER_DIVISION)
integer_division: Dividing integer expressions size and 2, and then converting
the integer quotient to type float. Any remainder, or fractional part of the
quotient, is ignored.
* Change job change type to remove when tile is outside allowed range.
* Swap try number and change type in job priority. To make sure remove jobs
always processed before any other.
Even when target is not reachable actor will try to run there either because
target navmesh polygon is selected within extended area or because partial path
is built to the closest possible polygon.
This saves cache capacity when a scene contains objects contantly transforming
by scripts and causing changes in navmesh. The probability to get cache hit for
such states is almost zero because even a constant change in a single float
value may give up to 2^32 different states.
