Finally fix the bug where dynamic-IP relays disappear when their

IP address changes: directory mirrors were mistakenly telling them
their old address if they asked via begin_dir, so they never got
an accurate answer about their new address, so they just vanished
after a day. Should fix bugs 827, 883, and 900 -- but alas, only
after every directory mirror has upgraded.

Changes in version 0.2.1.14-rc - 2009-04-11
o Security fixes:
- Avoid crashing in the presence of certain malformed descriptors.
Found by lark, and by automated fuzzing.
o Major features:
- Clients replace entry guards that were chosen more than a few months
ago. This change should significantly improve client performance,
especially once more people upgrade, since relays that have been
a guard for a long time are currently overloaded.
o Major bugfixes:
o Major bugfixes (on 0.2.0):

- Relays were falling out of the networkstatus consensus for
part of a day if they changed their local config but the
authorities discarded their new descriptor as "not sufficiently
different". Now directory authorities accept a descriptor as changed
if bandwidthrate or bandwidthburst changed. Partial fix for bug 962;
patch by Sebastian.
