Prior to this commit, the testsuite was failing on OpenBSD. After
this commit the testsuite runs fine on OpenBSD.
It was previously decided to test for the OpenBSD macro (rather than
__OpenBSD__, etc.) because OpenBSD forks seem to have the former
macro defined. sys/param.h must be included for the OpenBSD macro
definition; however, many files tested for the OpenBSD macro without
having this header included.
This commit includes sys/param.h in the files where the OpenBSD macro
is used (and sys/param.h is not already included), and it also
changes some instances of the __OpenBSD__ macro to OpenBSD.
See commit 27df23abb6 which changed
everything to use OpenBSD instead of __OpenBSD__ or OPENBSD. See
also tickets #6982 and #20980 (the latter ticket is where it was
decided to use the OpenBSD macro).

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.
Fixes bug 28995; bugfix on 0.3.5.1-alpha.

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.
