This patch reverts primary-backup-2.6.29-and-higher.sh. This script
is not safe for production enviroments until the commit phase
guarantees that the state-change propagation over netlink is
reliable. This script should be ready for 2.6.30 if the appropriate
kernel patches go into mainline in time.

This patch updates the script to remark the fact that it should be
used with Linux kernel < 2.6.29. Moreover, it adds a bulk-update
command after the commit in the primary path to avoid any race
condition (the backup may request a resync while this primary
is still committing the entries with an empty internal cache).
This is hackish, but I think that this is the best way to do this
for systems running a Linux kernel < 2.6.29.

This patch adds the clause PurgeTimeout that sets the new timer
when conntrackd -t is called. This command is particularly useful
when the sysadmin triggers hand-overs between several nodes without
rebooting as it reduces the timers of the remaining entries in
the kernel. Thus, avoiding clashes between new and old entries that
may trigger INVALID packets.

This patch reworks the documentation section. It removes the replicated
keepalived.conf files and merge all the scripts into one to reduce
confusion and improve maintainability.
It's likely that the documentation directory will suffer more
restructurations in the near future.
