o Code simplifications and refactorting:
- When we fixed bug 1038 we had to put in a restriction not to send
RELAY_EARLY cells for relay cells on rend circuits. This was necessary
as long as relays using Tor 0.2.1.3-alpha through 0.2.1.18-alpha were
active. Since this isn't the case anymore, we unify our behaviour here.
Implements bug 2081.
