server certificates when connecting as an SSL client from relays. it
works so far, but needs more testing and is currently lacking support
for certificate revocation (like CRL or OCSP). the file ssl_privsep.c
is extended to implement more code that should be in openssl to allow
loading the ca from chroot...

now sit between two SSL connections (Oitm - OpenBSD-in-the-middle),
accept SSL connections and forward to TCP, accept TCP connections and
forward to SSL, and do TCP to TCP of course.
This was tested by some people a while ago.

instead of flushing the complete source tracking table (sticky
addresses) in pf on host state changes, just flush the entries for
hosts that have been marked as down in the relayd table. this fixes
ugly problems with users loosing their sessions if another host or
redirection was going down.

arbitrary string in debugging mode, it will store an error code
(HCE_*) for each host. the error code can be translated to a string
(in log.c) for debugging but it will also be passed to relayctl via
the control socket.
from a user point of view, this will print a human-readable error
message in the "relayctl show hosts" output if a host is down because
the check failed. the relayctl(8) manpage includes detailed
explanations of the error messages including mitigations for the
most-common problems.

stickyness with web applications that cannot do the clustering on
their own and require stickyness with HTTP to HTTPS migration. this
is required in many cases; it is a true fact that we cannot always fix
the backend application in the real world.

nor chunked encoding. We don't know the length of the HTTP body in
this case, so it only works for single-pass HTTP responses without
subsequent HTTP response headers in the stream. You can still enforce
the Content-Length header with an "expect" rule.
For example, this fixes response handling from undeadly.org (thttpd)
if relayd is running as a transparent HTTP proxy.

faithd(8) by doing a similar mapping of IPv4/6 addresses with
relayd(8) and pf(4) redirections without the need of the faith(4)
interface. The trick works in both directions, it can accept IPv6
connections and relay them to IPv4 hosts by extracting the last 4
octets from the IPv6 destination (like faithd(8)), and it can accept
IPv4 connections and relay them to IPv6 hosts by prepending the 4
octets of the original IPv4 destination to a configured IPv6 prefix.
An access list is not needed because the classification is done in
pf.conf(5). It helps to get more faith in relayd.

singly-linked SLIST instead. the only noticeable change is the
reversed order to notify the children but it does not really matter
here. also only walk through the children host list if the host
itself is a potential parent.

inherit the state from another host with the specified Id; no
additional check will be for the inheriting host. This helps in
scenarios with lots of IP aliases that all point to the same service
on the same host (like web hosting with many SSL domains).

inet_pton/inet_ntop to allow specifing and printing the IPv6 scope
identifier. synced host_v6() with ntpd's version to use getaddrinfo()
instead of inet_pton() - host_v4, host_v6, and host_dns could all use
getaddrinfo in a single function by specifing different flags but this
would diverge from the other daemons using this common interface so we
keep this little overhead.
