Add ClientUseIPv6 and ClientPreferIPv6ORPort configuration options.

Use "preferred OR port" for all entry nodes, not only for bridges.

Mark bridges with "prefer IPv6 OR port" if an IPv6 address is
configured in Bridge line and ClientPreferIPv6ORPort is set.

Mark relays with "prefer IPv6 OR port" if an IPv6 address is found in
descriptor and ClientPreferIPv6ORPort is set.

Filter "preferred OR port" through the ClientUseIPv6 config option. We
might want to move this test to where actual connection is being set
up once we have a fall back mechanism in place.

Have only non-servers pick an IPv6 address for the first hop: We
don't want relays to connect over IPv6 yet. (IPv6 has never been used
for second or third hops.)

Implements ticket 5535.

I'm not entirely sure that this is meningful but I'm pretty sure it's
not harmful. Seems like the logical thing to do.

This is the preferred filename to use with Autoconf 2.50 and later.

specifically, specify what sort of routers we're fetching.

Reserve it for when new directory information arrives in response to
a fetch.

Resolves ticket 6760.

Addresses bug 6759.

Bugfix for #6732.

Fix for #6251

We are doing this merge to avoid taking the patch from
"nickm/disable_pathbias_warnings_v2" into 0.2.4 -- we're going to try
to fix the pathbias code for real here.

We've had over two months to fix them, and didn't.  Now we need
0.2.3.x stable.  Yes, it would be cool to get this working in
0.2.3.x, but not at the expense of delaying every other feature that
_does_ work in 0.2.3.x.  We can do a real fix in 0.2.4.

Conflicts:
	src/or/policies.c

a router that another router wasn't already connected to.

This can create a remote crash opportunity for/against directory
authorities.

This is important, since otherwise an attacker can use timing info
to probe the internal network.

Also, add an option (ExtendAllowPrivateAddresses) so that
TestingTorNetwork won't break.

Fix for bug 6710; bugfix on all released versions of Tor.
