In get_local_listener used by tor_ersatz_socketpair, the address
family used when binding the IPv6 socket was AF_INET instead of
AF_INET6.

Reported on tor-dev by Gisle Vanem. Bug not in any released Tor
(The suggested patch used _MSC_VER, but that's not how we do stuff
with autoconf. With autoconf, you detect the feature you want,
rather than trying to list all the systems that do or do not have
it.)
In theory it would be better to detect this bug in advance, but this
approach is much simpler, and therefore safer to backport.
This closes tor issue 28973.
This project introduces the prob_distr.c subsystem which implements all the
probability distributions that WTF-PAD needs. It also adds unittests for all of
them.

Hope is this will make it easier to test on the live tor network.
Does not need to be merged if we don't want to, but will come in handy
for researchers.

This implements all of the event handling, state machines, and padding
decisions for circuit padding.
I recommend reviewing this after you look at the call-in points into it from
the rest of Tor.

These callbacks allow the padding state machines to react to various types of
sent and received relay cells.

These event callbacks allow circuit padding to decide when to attempt to
launch and negotiate new padding machines, and when to tear old ones down.

This is a good code review start point, to get an overview of the interfaces
and types used in circuit padding.

We need this for padding negotiation so that we can have later machine
revisions supercede earlier ones.
