b95dd03e5f Log descriptions of nodes, not just nicknames.
This patch introduces a few new functions in router.c to produce a
more helpful description of a node than its nickame, and then tweaks
nearly all log messages taking a nickname as an argument to call these
functions instead.

There are a few cases where I left the old log messages alone: in
these cases, the nickname was that of an authority (whose nicknames
are useful and unique), or the message already included an identity
and/or an address.  I might have missed a couple more too.

This is a fix for bug 3045.

d41ac64ad6 Add UnixSocketsGroupWritable config flag
When running a system-wide instance of Tor on Unix-like systems, having
a ControlSocket is a quite handy mechanism to access Tor control
channel.  But it would be easier if access to the Unix domain socket can
be granted by making control users members of the group running the Tor
process.

This change introduces a UnixSocketsGroupWritable option, which will
create Unix domain sockets (and thus ControlSocket) 'g+rw'. This allows
ControlSocket to offer same access control measures than
ControlPort+CookieAuthFileGroupReadable.

See <http://bugs.debian.org/552556> for more details.

2b9c5ee301 Preserve bridge download status across SETCONF, HUP
This code changes it so that we don't remove bridges immediately when
we start re-parsing our configuration.  Instead, we mark them all, and
remove all the marked ones after re-parsing our bridge lines.  As we
add a bridge, we see if it's already in the list.  If so, we just
unmark it.

This new behavior will lose the property we used to have that bridges
were in bridge_list in the same order in which they appeared in the
torrc.  I took a quick look through the code, and I'm pretty sure we
didn't actually depend on that anywhere.

This is for bug 3019; it's a fix on 0.2.0.3-alpha.

da8297dbcb Handle transitions in Automap*, VirtualAddrNetwork correctly
Previously, if they changed in torrc during a SIGHUP, all was well,
since we would just clear all transient entries from the addrmap
thanks to bug 1345.  But if you changed them from the controller, Tor
would leave old mappings in place.

The VirtualAddrNetwork bug has been here since 0.1.1.19-rc; the
AutomapHosts* bug has been here since 0.2.0.1-alpha.

a3ae591115 When TrackExitHosts changes, remove all no-longer-valid mappings
This bug couldn't happen when TrackExitHosts changed in torrc, since
the SIGHUP to reload the torrc would clear out all the transient
addressmap entries before.  But if you used SETCONF to change
TrackExitHosts, old entries would be left alone: that's a bug, and so
this is a bugfix on Tor 0.1.0.1-rc.

09da83e1e8 Don't clear out transient addressmap entries on HUP
If you really want to purge the client DNS cache, the TrackHostExits
mappings, and the virtual address mappings, you should be using NEWNYM
instead.

Fixes bug 1345; bugfix on Tor 0.1.0.1-rc.

Note that this needs more work: now that we aren't nuking the
transient addressmap entries on HUP, we need to make sure that
configuration changes to VirtualAddressMap and TrackHostExits actually
have a reasonable effect.

61c06cbc66 Teach retry_listener about "auto" ports.
Otherwise, it will just immediately close any port declared with "auto"
on the grounds that it wasn't configured.  Now, it will allow "auto" to
match any port.

This means FWIW if you configure a socks port with SocksPort 9999
and then transition to SocksPort auto, the original socksport will
not get closed and reopened.  I'm considering this a feature.

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.

Previously we ensured that it would get called periodically by doing

Clients and relays haven't used them since early 0.2.0.x.  The only
remaining use by authorities learning about new relays ahead of scedule;
see proposal 147 for what we intend to do about that.

We're leaving in an option (FetchV2Networkstatus) to manually fetch v2
networkstatuses, because apparently dnsel and maybe bwauth want them.

This fixes bug 3022.
