Temporarily removes agent from navigation map when parent node cannot process due to SceneTree pause and process_mode property. Normal process_mode does not work as other agents would still avoid the paused agents because they were still active on the navigation map and the rvo world. Also fixes potential crash when region_get_map or agent_get_map is called while no map is set.

Exposes get_rid() function for scripting.
Adds configuration warning when obstacle is used with not intended static body parent.

Fixes NavigationObstacle2D/3D reporting a 'get_global_transform: Condition "!is_inside_tree()" error when estimating the agent radius.
The collisionshapes that are lower in the SceneTree order than the obstacle node are not loaded in the SceneTree yet so the global_transform function fails.
Also adds warning message when this happens.
(cherry picked from commit cc707412e9)
Change the entire navigation system.
Remove editor prefix from nav mesh generator class. It is now used for baking
at runtime as well.
Navigation supports obstacle avoidance now with the RVO2 library.
Nav system will also automatically link all nav meshes together to form one
overall complete nav map.
