3da661b242 Advertise correct DirPort/ORPort when configured with "auto"
We'll eventually want to do more work here to make sure that the ports
are stable over multiple invocations.  Otherwise, turning your node on
and off will get you a new DirPort/ORPort needlessly.

59f9097d5c Hand-conversion and audit phase of memcmp transition
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

6dfc0d5301 Avoid false positives from proxy_mode()
Previously it would erroneously return true if ListenAddr was set for
a client port, even if that port itself was 0.  This would give false
positives, which were not previously harmful... but which were about
to become.

Partial backport of daa0326aaa .

git) and on 0.2.1.30 (for the part where we dumped micro-revisions.)

026e7987ad Sanity-check consensus param values
We need to make sure that the worst thing that a weird consensus param
can do to us is to break our Tor (and only if the other Tors are
reliably broken in the same way) so that the majority of directory
authorities can't pull any attacks that are worse than the DoS that
they can trigger by simply shutting down.

One of these worse things was the cbtnummodes parameter, which could
lead to heap corruption on some systems if the value was sufficiently
large.

This commit fixes this particular issue and also introduces sanity
checking for all consensus parameters.

cec21652a7 Try harder not to exceed the 50 KB extra-info descriptor limit.
Our checks that we don't exceed the 50 KB size limit of extra-info
descriptors apparently failed. This patch fixes these checks and reserves
another 250 bytes for appending the signature. Fixes bug 2183.

213139f887 Properly refcount client_identity_key
In a2bb0bf we started using a separate client identity key. When we are
in "public server mode" (that means not a bridge) we will use the same
key. Reusing the key without doing the proper refcounting leads to a
segfault on cleanup during shutdown. Fix that.

Also introduce an assert that triggers if our refcount falls below 0.
That should never happen.

03adb8caad Add some asserts to get_{tlsclient|server}_identity_key
We now require that:
  - Only actual servers should ever call get_server_identity_key
  - If you're being a client or bridge, the client and server keys should
    differ.
  - If you're being a public relay, the client and server keys
    should be the same.

ef5925237d First cut of code to enable RefuseUnknownExits
The RefuseUnknownExits config option is now a tristate, with "1"
meaning "enable it no matter what the consensus says", "0" meaning
"disable it no matter what the consensus says", and "auto" meaning "do
what the consensus says".  If the consensus is silent, we enable
RefuseUnknownExits.

This patch also changes the dirserv logic so that refuseunknownexits
won't make us cache unless we're an exit.
