Tweaks to test-connection patch: use ".noconnect" instead of ".test" (since there are lots of ways to test things). Use a regular sequence of STREAM events (NEW followed by CLOSED) instead of a new event type. Make the function that checks the address be static and use const and strcasecmpend properly.

Let directory authorities set the BadExit flag if they like. Also, refactor directory authority code so we can believe multiple things about a single router, and do fewer linear searches.
svn:r8794
Fix longstanding bug in connection_exit_begin_conn(): Since connection_edge_end() exits when the connection is unattached, we were never sending RELAY_END cells back for failed RELAY_BEGIN attempts. Fix this. This might make clients that were otherwise timing out either fail faster or retry faster, which is good news for us.
svn:r8770
Add pragma:no-cache and expires headers so that directory lookups can work better in the presence of caching HTTP proxies. (I would have used Cache-Control, but that is an HTTP/1.1 thing.) All timeouts are currently wild-assed guesses.
svn:r8765
Never discard a descriptor for being too old until either it is recommended by no authorities, or until we download a better (more recent and recommended) one for the same router. This will eventually make it possible for servers to publish less often.
svn:r8761
Add client support for a 'BadExit' flag, so authorities can say "Server X is a poor choise for your nytimes.com connections, as it seems to direct them to HoorayForMao.com or (more likely) WouldYouLikeToBuyTheseFineEncyclopedias.com"
svn:r8690
Touch up last patch (to add REASON to CIRC events): make some reasons
more sensible, send reasons only to controllers that have enabled
extended events, and clean up whitespace.
svn:r8672
Add USEFEATURE to control changes to control protocol. Use like __future__ directive from Python. Will spec before pushing changes. No, really. :)
svn:r8584
Partial implementation of revised nickname syntax for controllers. Implement ability to look up routers by "verbose" nicknames; add a per-v1-control-connection flag to turn the feature on in events. Needs testing, spec, ability to actually turn on the flag, double-checking that we wont overflow any nickname buffers, and changelog.
svn:r8582
hidden service authorities too.
- Just because your DirPort is open doesn't mean people should be
able to remotely teach you about hidden service descriptors. Now
only accept rendezvous posts if you've got HSAuthoritativeDir set.
svn:r8573
Disprefer exit nodes for entry, middle positions (fixes bug 200). Also, switch to using a uint64_t to hold "total bandwidth for all nodes" under consideration; crypt_rand_int would have died at 2GB/s network capacity.
svn:r8571
Reserve the nickname "Unnamed" for routers that can't pick a hostname; any
router can call itself Unnamed; directory servers will never allocate Unnamed
to any particular router; clients won't believe that any router is the
canonical Unnamed.
svn:r8529
[Needs review.] Add a BEGIN_DIR relay cell type for an easier
in-protocol way to connect to directory servers through Tor.
Previously, clients could only connect to director servers over Tor
from exit nodes, but couldn't get directory information anonymously
from a non-exit cache without getting a directory server involved.
This needs testing, and needs client-side code to actually exercise it.
svn:r8527
Make "is a v1 authority", "is a v2 authority", and "is a hidden service authority" into separate flags so we can eventually migrate more trust away from moria.
svn:r8523
Refactor entry guard status logic a lot; allow more factors [like not
having a Guard flag or being listed in ExcludeNodes] to render a guard
"unlisted" (now called "unusable"); track guard down status (now
called "unreachable") separately from is_running.
svn:r8519
client asks us to resolve (not connect to) an address, and we have a
cached answer, give them the cached answer. Previously, we would give
them no answer at all.
svn:r8478
I tracked a bug in server-side reverse DNS to something concerning the caching code. Ive disabled server-side cacheing for reverse DNS answers for now, and I am noting the bug in the TODO.
