ff62154ba3 New config options WarnPlaintextPorts and RejectPlaintextPorts so
Tor can warn and/or refuse connections to ports commonly used with
vulnerable-plaintext protocols.

We still need to figure out some good defaults for them.

Here, have some terribly clever new buffer code.  It uses a mbuf-like strategy rather than a ring buffer strategy, so it should require far far less extra memory to hold any given amount of data.  Also, it avoids access patterns like x=malloc(1024);x=realloc(x,1048576);x=realloc(x,1024);append_to_freelist(x) that might have been contributing to memory fragmentation.  I've  tested it out a little on peacetime, and it seems to work so far.  If you want to benchmark it for speed, make sure to remove the #define PARANOIA; #define NOINLINE macros at the head of the module.

15c048bdc5 Fix several remotely triggerable asserts based on DirPort requests
for a v2 or v3 networkstatus object before we were prepared. This
was particularly bad for 0.2.0.13 and later bridge relays, who
would never have a v2 networkstatus and would thus always crash
when used. Bugfixes on 0.2.0.x.

Estimate the v3 networkstatus size more accurately, rather than
estimating it at zero bytes and giving it artificially high priority 
compared to other directory requests. Bugfix on 0.2.0.x.

75c38a2c88 Bridges now behave like clients with respect to time intervals for
downloading new consensus documents. Bridge users now wait until
the end of the interval, so their bridge will be sure to have a
new consensus document.

8de470cf69 Add "GETINFO/desc-annotations/id/<OR digest>" so controllers can
ask about source, timestamp of arrival, purpose, etc. We need
something like this to help Vidalia not do GeoIP lookups on bridge 
addresses.

3ff63b6f4e When the DANGEROUS_VERSION controller status event told us we're
running an obsolete version, it used the string "OLD" to describe
it. Yet the "getinfo" interface used the string "OBSOLETE". Now use
"OBSOLETE" in both cases.

d46b8a3eac Stop being so aggressive about fetching dir info if your DirPort is
on but your ORPort is off.

Add a new config option BridgeRelay that specifies you want to
be a bridge relay. Right now the only difference is that it makes
you answer begin_dir requests, and it makes you cache dir info,
even if your DirPort isn't on.

Refactor directory_caches_dir_info() into some more functions.

Change tor_addr_t to be a tagged union of in_addr and in6_addr, not of sockaddr_in and sockaddr_in6.  It's hardly used in the main code as it is, but let's get it right before it gets popular.

466abecef4 Our new v2 hidden service descriptor format allows descriptors
that have no introduction points. But Tor crashed when we tried
to build a descriptor with no intro points (and it would have
crashed if we had tried to parse one). Bugfix on 0.2.0.x; patch

91bb09cb28 Only update guard status (usable / not usable) once we have
enough directory information. This was causing us to always pick
two new guards on startup (bugfix on 0.2.0.9-alpha), and it was
causing us to discard all our guards on startup if we hadn't been
running for a few weeks (bugfix on 0.1.2.x). Fixes bug 448.

d6f8ba25c9 back out r12509 and fix a better bug instead:
When authorities detected more than two relays running on the same
IP address, they were clearing all the status flags but forgetting
to clear the "hsdir" flag. So clients were being told that a
given relay was the right choice for a v2 hsdir lookup, yet they
never had its descriptor because it was marked as 'not running'
in the consensus.
