Fix various cases where re-init could get things blocked. Remove the duplicate storage of the active paths; now we always check the primary data, and hence it can’t be out of sync. Also remove the obsolete persistent cache code. Fixes some of the issues discussed in: https://sourceforge.net/p/flightgear/codetickets/2308/ Further improvements still to come, especially to retry on a better schedule for intermittent connections.
