 PT 2.0 additions. There aren't really standard names for these.
 > 1. IPC manager/dispatcher. As far as I know, tor and
 [https://github.com/twisteroidambassador/ptadapter] are the only two
 implementations of this. This is the thing that sets e.g.
 `TOR_PT_MANAGED_TRANSPORT_VER` and manages subprocesses of type (2).

 The module within Tor Launcher that implements Moat (interactive bridge
 retrieval) is another example of the above. We did that so we could reuse
 your Meek PT implementation. See https://gitweb.torproject.org/tor-
 launcher.git/tree/src/modules/tl-bridgedb.jsm?h=maint-0.2.18#n188
