Queries a bvhcache for the cache bvhtree of the request type

When the r_locked is filled and the tree could not be found the caches mutex will be locked. This mutex can be unlocked by calling bvhcache_unlock.

When r_locked is used the mesh_eval_mutex must contain the Mesh_Runtime.eval_mutex.

Builds a BVH tree where nodes are the relevant elements of the given mesh. Configures BVHTreeFromMesh.

The tree is build in mesh space coordinates, this means special care must be made on queries so that the coordinates and rays are first translated on the mesh local coordinates. Reason for this is that bvh_from_mesh_* can use a cache in some cases and so it becomes possible to reuse a BVHTree.

free_bvhtree_from_mesh should be called when the tree is no longer needed.
