fdbefc8934 If we're a relay, avoid picking ourselves as an introduction point,
a rendezvous point, or as the final hop for internal circuits. Bug
reported by taranis and lodger. Bugfix on 0.1.2.x.

4fb573fddd bugfix on r10612:
When we load a bridge descriptor from the cache,
and it was previously unreachable, mark it as retriable so we won't
just ignore it. Also, try fetching a new copy immediately.

Refactor circuit_launch* functions to take a bitfield of flags rather than 4 separate nonconsecutive flags arguments.  Also, note a possible but in circuit_find_to_cannibalize, which seems to be ignoring its purpose argument.

73ff2e5d5e Fix a crash when we fetch a descriptor that turns out to be
unexpected (it used to be in our networkstatus when we started
fetching it, but it isn't in our current networkstatus), and we
aren't using bridges. Bugfix on 0.2.0.x.

52363d23d7 If we can't expand our list of entry guards (e.g. because we're
using bridges or we have StrictEntryNodes set), don't mark relays
down when they fail a directory request. Otherwise we're too quick
to mark all our entry points down.

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.

193a144c9f Make "UpdateBridgesFromAuthority" torrc option work: when bridge
users configure that and specify a bridge with an identity
fingerprint, now they will lookup the bridge descriptor at the
default bridge authority via a one-hop tunnel, but once circuits
are established they will switch to a three-hop tunnel for later
connections to the bridge authority.

Add a line to the state file for each guard to let us know which version added the guard.  If the line is absent, assume the guard was added by whatever version of Tor last wrote the state file.  Remove guards if the version that added them was using a bad guard selection algorithm.  (Previously, we removed guards if the version that wrote the file was using a bad guard selection algorithm, even if the guards themselves were chosen by a good version.)

99bfb1bebe If there's a never-before-connected-to guard node in our list,
never choose any guards past it. This way we don't expand our

something.

237cdfdf48 if we already have a bridge in our state file, it won't be
in the networkstatuses, so we'll mark it unusable when we
load it, and then when we get a new routerinfo for it, we'll
still think it's unusable. fix that.

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.
