o Minor bugfixes (hidden services):
- When fetching hidden service descriptors, check not only for
whether we got the hidden service we had in mind, but also
whether we got the particular descriptors we wanted. This
prevents a class of inefficient but annoying DoS attacks by
hidden service directories. Fixes bug 13214; bugfix on
0.2.1.6-alpha. Reported by "special".
