Without these two iptables rules (one for UDP encapsulated IPsec and
another for direct IPsec), ovs-vswitchd would incorrectly conclude
that GRE packet belonged to a plain GRE tunnel instead of IPsec GRE
tunnel.

ovs-monitor-ipsec uses the OVS database to get configuration, so don't
bother starting the daemon until it's up.
Debian recently switched to using the LSB fields in the header of init
scripts to allow dependency-based boots. This is described in the
following page:
http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot
This commit makes use of those fields to get the ordering we want.
The ovs-monitor-ipsec init script used the old "pidfile-name"
instead of the new "pidfile" option. This should cause it to fail
when starting.
This patch also causes ovs-monitor-ipsec to create a log file.
dh_pysupport that the packaging used until now is deprecated, with
dh_python2 as its successor.
This commit removes the PYTHONPATH setting from
debian/openvswitch-ipsec.init because it is not needed, as the Python
packaging is public. In fact, the Python packaging was public,
unintentionally, before, so the PYTHONPATH could have been removed earlier.
Brad pointed out that openvswitch-ipsec init script defined the variable
DIETIME but attempted to use it as DODTIME. This commit uses DODTIME,
since it's the name used by the openvswitch-switch init script. The
openvswitch-controller init script had the same issue.
As suggested by Ben, the "s" suffixes are removed from sleep commands,
since they are a GNU extension.

The ovs-monitor-ipsec daemon monitors the Interface table for GRE
entries. If an entry specifies other-config parameters "ipsec-local-ip"
and ("ipsec-psk" or "ipsec-cert"), it will create the appropriate
security associations so that all GRE traffic to the remote host will be
encrypted. In order for the two GRE tunnels to communicate, both sides
need to be configured for IPsec with appropriate authentication.
Currently, ovs-monitor-ipsec does not support certificate authentication
or ensure that an interface is actually attached to a bridge. Both of
these issues will be addressed in a forthcoming patch.
NB: While GRE-over-IPsec should work on any system with a relatively
recent racoon and setkey, it has only been tested on Debian. As such,
only Debian packaging has been provided.
