There were two issues discovered:
- Triangles mapping didn't free in buildNavMeshData if there's no recast data for an object
- KX_NavMeshObject used not-guarded allocation for polygons storage, but used guarded
freeing stuff to free used memory, producing error messages in the console and leading to
memory leak.
Wasn't actually harmful for users -- there was no memory corruptions and error happens only
when object was set up in a way when navmesh can't work in theory.
- Upgrade Recast library to latest portable version
- Implement recast_qsort based on FreeBSD qsort.c to have
portable thread safe quick sort for use in conversion routine.
- Better default value for the Build Navigation Mesh operator
- Some declarations after statement left.
- Do not use static inline functions in MOD_navmesh. It produces errors
with msvc and not sure it's actually helps -- optimizer should
make it inlined itself.
