Fixed calls referring to sockaddr length so they work
with FreeBSD.
Try target addresses in turn until one works if
there are several (e.g. "localhost:22" resolves to
an IPv6 address and an IPv4 address and sshd does
not listen on IPv6).
Fixed sslh-fork so killing the head process kills
the listener processes.
Heavily cleaned up test suite. Added stress test
t_load script. Added coverage (requires lcov).
Support for XMPP (Arnaud Gendre).
Updated README.MacOSX (Aaron Madlon-Kay).
