This is to send dbus events on major cluster events:
- membership changes
- application connect/dissconnet from corosync
- quorum changes
dbus events can then be converted into snmp traps by foghorn or
corosync-notifyd can be run to directly send snmp traps.

Some switches delay multicast packets vs the unicast token. This patch works
around that problem by providing a new tuneable called miss_count_const. This
tuneable works by counting the number of times a message is found missing
and once reaching the const value, marks it as missing in the retransmit list.
This improves performance and doesn't display warning messages about missed
multicast messages when operating in these switching environments.

This prevents a shared mem leak if corosync dies while clients
are connected.
Calling cpg_finalize() did not release the shared mem as
coroipcc_msg_send_reply_receive() returned an error and
thus coroipcc_service_disconnect() did not get called.

This may typically happen if local firewall is enabled. Patch adds new
item to statistics called continuous_gather where is number of
continuous entered gather state. If this number is bigger then
MAX_NO_CONT_GATHER, warning message is displayed. This is also used on
exiting, so stop of corosync is now possible even with enabled firewall.

that occur as a result of the design of udpu. Totem no longer requires
the flushing technique because we don't mark a packet as missing until it has
not been seen by a certain number of token rotations per a previous patch. This
mechanism was introduced to work around a problem in switches where multicast
messages may be delayed by long periods compared to the unicast token.
This patch removes the flushing logic from udpu since it is no longer necessary.

The UDPU transport is useful for those deployments which can't use multicast.
UDPU works by using UDP unicast, which is fully supported by every switch
manufacturer by default and doesn't rely on a functional IGMP implementation.
An example of the UDPU transport is contained in the corosync.conf.example.udpu
file which shows a 16 node cluster. This file should be copied to each node
in the cluster and IP addresses changed as appropriate.
Amended to remove dead udpu REUSEADDR socket option.
