Comment:

 I've rewritten large sections of the code for setting a bridge as being
 blocked, or its transports, or some of its transports, or some ports, or
 some addresses, and any combination of any of that. This code is in the
 new `bridgedb.bridges.Bridge`
 [https://gitweb.torproject.org/user/isis/bridgedb.git/tree/lib/bridgedb/bridges.py?h=develop#n777
 class] that was introduced for #9380.

 I've decided for #12505 to remove all the remnant code from #5027. It
 needed to be entirely refactored. The database table which was set up for
 the code hasn't ever been used, so I'm ripping the whole thing out.

 The last pieces that we'll need are:

  * (#12031) A way to store info for blocked bridges in the new databases.
 This should be quite simple given the new data structures and the methods
 exposed by the new `bridgedb.bridges.Bridge` class.

  * (#12547) We'll need parsers for the `bridge_reachability`
 [http://pipeline.infra.ooni.nu/CN/ reports created by OONI].
