6a9e693fbe Suppress "decided to publish new descriptor" message when not a server
The message only means that we're publishing a new descriptor when we
are actually in some kind of server mode, and publication is on.

Fix for bug 3942; bugfix on 0.2.3.2-alpha.

5fed1ccd90 put a _ before or_options_t elements that aren't configurable
it's fine with me if we change the current convention, but we should
actually decide to change it if we want to.

Conflict was in or_options_free, where two newly added fields had free
calls in the same place.

10232dc042 Pass OR address to PT proxy, even with IPv6 or ORListenAddress.
Introduce get_first_listener_addrport_for_pt() which returns a string
containing the addrport of the first listener we could find. Use it to
form the TOR_PT_ORPORT managed proxy protocol line.

fedf76a2e6 Introduce and use router_get_active_listener_port_by_type().
router_get_active_listener_port_by_type() iterates all connections,
trying to find a listener of a specific type, and returns its TCP
port.

a74905cea4 We allow IPv6 connections, don't use sockaddr_in with getsockname
This fixes client_check_address_changed to work better with IPv6 Tor
clients, and prevents them from spewing errors. Fix for ticket 5537.

cc35157805 Twiddle ROUTER_{MAX_COSMETIC_TIME_DIFFERENCE,MAX_AGE_TO_PUBLISH}
This is ticket 2479. Roger's original explanation was:

   We have a series of bugs where relays publish a descriptor within
   12 hours of their last descriptor, but the authorities drop it
   because it's not different "enough" from the last one and it's
   too close to the last one.

   The original goal of this idea was to a) reduce the number of new
   descriptors authorities accept (and thus have to store) and b)
   reduce the total number of descriptors that clients and mirrors
   fetch. It's a defense against bugs where relays publish a new
   descriptor every minute.

   Now that we're putting out one consensus per hour, we're doing
   better at the total damage that can be caused by 'b'.

   There are broader-scale design changes that would help here, and
   we've had a trac entry open for years about how relays should
   recognize that they're not in the consensus, or recognize when
   their publish failed, and republish sooner.

   In the mean time, I think we should change some of the parameters
   to make the problem less painful.

5193752ca8 Exits don't need to fetch certs for unknown authorities
When we started RefuseUnknownExits back in 0.2.2.11-alpha, we
started making exits act like they cache directory info (since they
need an up-to-date idea of who is really a router).  But this
included fetching needless (unrecognized) authorities' certs, which
doesn't make any sense for them.

This is related to, but not necessarily the same as, the issue that
Ian reported for bug #2297.

(This patch is based on a patch from a user who I believe has asked
not to be named.  If I'm wrong about that, please add the
appropriate name onto the changelog.)

491ffa540f Move router lookup to _after_ we assert that its argument is set
A previous commit in the 5527 branch had moved
router_get_mutable_by_digest(digest_rcvd) to happen before we did
tor_assert(digest_rcvd), which would have defeated the purpose of
the assert.

3031def726 checking "same addr/port but with nonmatching keys" is obsolete
Specifically, I believe it dates back to when extend cells had address:port
but no digest in them. The special edge case is certainly not worth the
complexity these days.

734fad4103 Make relays handle an address suggestion from a directory server giving an IPv6 address.
last_guessed_ip becomes a tor_addr_t.

about IPv6 (resolve_my_address() is still IPv4 only).

b5a8c3aa00 Remove misleading function comment (bug 5324)
In the distant past, connection_handle_read() could be called when there
are pending bytes in the TLS object during the main loop. The design
since then has been to always read all pending bytes immediately, so
read events only trigger when the socket actually has bytes to read.

Resolves bug 5324.
