    Minimal implementation of bridge-distribution-request
    
    Just advertise the line when we're a bridge, using "any" if we're
    published or "none" if we aren't.
    
    This is done in lieu of a full backport of #18329.

+  o Minor features (bridge):
+    - Bridges now include notice in their descriptors that they are bridges,
+      and notice of their distribution status, based on their publication
+      settings.  Implements ticket 18329.  For more fine-grained control of
+      how a bridge is distributed, upgrade to 0.3.2.x or later.
