The OutboundBindAddress option is useful for making sure that all of
your outbond connections use a given interface. But when connecting
to 127.0.0.1 (or ::1 even) it's important to actually have the
connection come _from_ localhost, since lots of programs running on
localhost use the source address to authenticate that the connection
is really coming from the same host.
Our old code always bound to OutboundBindAddress, whether connecting
to localhost or not. This would potentially break DNS servers on
localhost, and socks proxies on localhost. This patch changes the
behavior so that we only look at OutboundBindAddress when connecting
to a non-loopback address.
this case can now legitimately happen, if you have a cached v2 status
from moria1, and you run with the new list of dirservers that's missing
the old moria1. it's nothing to worry about; the file will die off in
a month or two.

Refactor a bit so that it is safe to include math.h, and mostly not needed.
introduced this line:
tor_resolve_LDADD = -lm ../common/libor.a @TOR_LIB_WS32@
which caused the build to fail, because only ../common/libor.a
(via the embedded ../common/util.o via ../common/util.c)
referenced libm's `lround' and `log' symbols, so that the
linker (GNU ld) didn't bother to import those symbols before
reading ../common/libor.a, thus leaving those symbols undefined.
The solution was to swap the order, producing the line:
tor_resolve_LDADD = ../common/libor.a -lm @TOR_LIB_WS32@

...to let us
rate-limit client connections as they enter the network. It's
controlled in the consensus so we can turn it on and off for
experiments. It's starting out off. Based on proposal 163.
Specifically, there are two cases: a) are we willing to start a new
circuit at a node not in your ExitNodes config option, and b) are we
willing to make use of a circuit that's already established but has an
unsuitable exit.
Now we discard all your circuits when you set ExitNodes, so the only
way you could end up with an exit circuit that ends at an unsuitable
place is if we explicitly ran out of exit nodes, StrictNodes was 0,
and we built this circuit to solve a stream that needs solving.
Fixes bug in dc322931, which would ignore the just-built circuit because
it has an unsuitable exit.
Before it would prepend your requested entrynodes to your list of guard
nodes, but feel free to use others after that. Now it chooses only
from your EntryNodes if any of those are available, and only falls back
to others if a) they're all down and b) StrictNodes is not set.
Also, now we refresh your entry guards from EntryNode at each consensus
fetch (rather than just at startup and then they slowly rot as the
network changes).
The goal here is to make users less likely to set StrictNodes, since
it's doing closer to what they expect it should be doing.
