/**
* \file btrack.c
* \brief Bootstrap trackers
*
* Initializes and shuts down the specific bootstrap trackers. These
* trackers help the reporting of bootstrap progress by maintaining
* state information about various subsystems within tor. When the
* correct state changes happen, these trackers emit controller
* events.
*
* These trackers avoid referring directly to the internals of state
* objects of other subsystems.
*
* btrack_circuit.c contains the tracker for origin circuits.
*
* btrack_orconn.c contains the tracker for OR connections.
*
* Eventually there will be a tracker for directory downloads as well.
