e5885deab5 Separate "SOCKS_COMMAND_CONNECT_DIR" into two flags in
edge_connection_t: want_onehop if it must attach to a circuit with
only one hop (e.g. for the current tunnelled connections that use
begin_dir), and use_begindir if we mean to use a BEGIN_DIR relay
command to establish the stream rather than the normal BEGIN. Now
we can make anonymized begin_dir connections for (e.g.) more secure
hidden service posting and fetching.

8641439a6e backport candidate (revert part of r9350):
Expire application streams in all cases if they've been around
longer than SocksTimeout. Right now there are some cases where the
stream will live forever, demanding a new circuit every 15 seconds.
Bugfix on 0.1.2.7-alpha; fixes bug 454; reported by lodger.

3d641bde0e Refine r10571: more work on bridge stuff.
- 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.

af658b7828 More work towards making bridge users able to connect via bridges:
- 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.

Fix handling of resolves with very long or otherwise malformed addresses, and comment dns_resolve better, and stop making what should be a BUG warning into an assert(0).  This fixes bug 427, which was introduced around 9900/9931/9932.  Not a backport candidate: 0.1.2.x never had this bug.

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.

37b5132ad8 Expire socks connections if they spend too long waiting for the
handshake to finish. Previously we would let them sit around for
days, if the connecting application didn't close them either.

Also take this opportunity to refactor a duplicate bit of circuituse.c.

And change the semantics of SocksTimeout slightly, but I think it'll
be ok.
