[tor-commits] [tor/master] Track bootstrap phase independently of progress

commit 687bf3ea645ef8c5ce8c9f02a25274121ca13318

    Track bootstrap phase independently of progress
    
    Track bootstrap phase (enumerated by bootstrap_status_t) independently
    from the bootstrap progress (which can represent intermediate
    progress).  This allows control_event_bootstrap_problem() to avoid
    doing a linear search through the bootstrap progress space to find the
    current bootstrap phase.
