Removed log_format from core/manager as it already exists in Manager.
Added locks around Openflow::Datapath's methods to avoid race-conditions with datapath manager getting host datapath event.
Call super after manager initializes variables to ensure logging, etc, works.
Added node_id to Datapath.
Allow searching for host datapath and make sure there's only ever one host datapath loaded.
Properly send event for unloaded items.
Fixed wait_for_loaded timer.
Fixed datapath deletion events.
Use wait_for_loaded/unloaded for initializing datapath.
