More directory voting code. Now, if everything works, and I haven't forgotten anything, it is possible to set up some v3 authorities and start voting. Of course, I have probably forgotten something, and there are probably bugs in there somewhere too.

- Only listen to responses for "authority" fetches if we're configured
to use Bridges. Otherwise it's safe (and maybe smarter) to silently
discard them like we used to.
- React faster to download networkstatuses after the first bridge
descriptor arrives.
- Don't do dir fetches before we have any bridges, even when our
dirport is open.
svn:r10604
- demand options->Bridges and options->TunnelDirConns if
options->UseBridges is set.
- after directory fetches, accept descriptors that aren't referenced by
our networkstatuses, *if* they're for a configured bridge.
- delay directory fetching until we have at least one bridge descriptor.
- learn how to build a one-hop circuit when we have neither routerinfo
nor routerstatus for our destination.
- teach directory connections how to pick a bridge as the destination
directory when doing non-anonymous fetches.
- tolerate directory commands for which the dir_port is 0.
- remember descriptors when the requested_resource was "authority",
rather than just ignoring them.
- put bridges on our entry_guards list once we have a descriptor for them.
When UseBridges is set, only pick entry guards that are bridges. Else
vice versa.

Partial backport candidate: do not rely on finding a \0 after an mmaped() router/extrainfo file. Also, set journal length correctly when starting up.
svn:r10248
Partial backport candidate: We had a bug where we were downloading descriptors by descriptor digest, but trying to look them up by identity fingerprint when updating their failure count and next retry time. (Also use correct backoff logic for extrainfo code.) Needs testing, doubtless.
svn:r10210
authorities should set. This will let future authorities choose
not to serve V2 directory information.
Also, go through and revamp all the authdir_mode stuff so it tries
to do the right thing if you're an auth but not a V1 or V2 auth.
svn:r10092
(Needs review.) Allow directory authorities to accept multiple router descriptors and extra info documents in a single POST. This will make implementing the client side of proposal 104 a lot simpler.
svn:r10069
Initial version of patch from Karsten Loesing: Add an HSAuthorityRecordStats option to track statistics of overall hidden service usage without logging information that would be useful to an attacker.
svn:r10067
Initial version of code to stop using socket pairs for linked connections. Superficially, it seems to work, but it probably needs a lot more testing and attention.
svn:r9995
More proposal-104 stuff: add most of the code for authorities to accept and serve extra-info documents. The back-end to store the things is missing.
svn:r9971
Make all LD_BUG log messsages get prefixed with "Bug: ". Remove manually-generated "Bug: "s from log-messages. (Apparently, we remembered to add them about 40% of the time.)
