o Minor bugfixes:
- Warn and drop the circuit if we receive an inbound 'relay early'
cell. Those used to be normal to receive on hidden service circuits
due to bug 1038, but the buggy Tor versions are long gone from
the network so we can afford to resume watching for them. Resolves
the rest of bug 1038; bugfix on 0.2.1.19.

o Minor bugfixes:
- Correct a confusing error message when trying to extend a circuit
via the control protocol but we don't know a descriptor or
microdescriptor for one of the specified relays. Fixes bug 12718;
bugfix on 0.2.3.1-alpha.
