Option is used for automatic generating of multicast address. If both
cluster_name and mcastaddr options are specified, mcastaddr takes
precedence.

Our preferred shared logging system is exported via the libqb library. As
a result, the corosync project no longer needs to export logsys.so and the
code can be directly included in the binary. The header file can also be
removed.

There were too much false positives with passive mode rrp when high
number of messages were received.
Patch adds new configurable variable rrp_problem_count_mcast_threshold
which is by default 10 times rrp_problem_count_threshold and this is
used as threshold for multicast packets in passive mode. Variable is
unused in active mode.

Previous default (50) was too low for most modern switch hardware. This
may trigger abort because the aru doesn't increase for 50 token
rotations combined with a defect in how failed to recv conditions are
handled. By increasing this tunable, the condition should no longer
trigger the errant code.

This patch automatically recovers redundant ring failures.
Please note that this patch introduced rrp_autorecovery_check_timeout
in totem config hence breaks internal ABI. The internal ABI users
of totem.h need to rebuild their binaries.

1) both IPv4 and IPv6 mcast should default to ttl=1
2) the range should be 0..255
0 is valid meaning localhost only (cluster of one)

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.

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.

1. the reload callback was not sent to the library,
2. totem exponentially added new callbacks because the old ones were not
removed properly.
