Change configuration strategy for eventdns. Instead of elaborate option set, just allow the user to specify another resolv.conf to use.

Fix bug 314: Instead of checking address_in_virtualrange, check addressmap_have_mapping().  This should be more accurate.  [Rename to addressmap_have_mapping() from addressmap_already_mapped().]

Shortening fields is only one part of making structs shorter. You must also consider alignment padding. Whee.

Patch from Tup to add support for transparent AP connections: this basically bundles the functionality of trans-proxy-tor into the tor mainline.  Now hosts with compliant pf/netfilter implementations can redirect TCP connections straight to Tor without diverting through SOCKS.

7239262f71 Don't tell anybody, but we're going OO here. This patch splits
circuit_t into origin_circuit_t and or_circuit_t.  I fixed some
segaults; there may be more.  We still need to move more rendezvous
stuff into subtypes.

This is a trial run for splitting up connection_t; if the approach is
insane, please say so soon so we can do something smarter.

Also, this discards the old HALF_OPEN code, which nobody seems to
want.

892f671f59 Define a schedule for how long to wait between retrying
application connections. Rather than waiting a fixed amount of
time between each retry, we wait only 5 seconds for the first,
10 seconds for the second, and 15 seconds for each retry after
that. Hopefully this will improve the expected experience.

Addresses bug 297.

9db7b2c068 Allow servers with no hostname or IP address to learn their IP address
by asking the directory authorities. This code only kicks in when you
would normally have exited with a "no address" error.

This design is flawed, though, since the X-Your-Address-Is header is not
authenticated, and doing it this way introduces too many new attacks. The
right answer is to give IP address hints inside the HELLO cell; much of
this code can be reused when we switch.

05d0b70573 Get rid of the router_retry_connections notion. Now routers no longer
try to rebuild long-term connections to directory authorities, and
directory authorities no longer try to rebuild long-term connections to
all servers.

We still don't hang up connections in these two cases though -- we need
to look at it more carefully to avoid flapping, and we likely need to
wait til 0.1.1.x is obsolete.
