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.

If all interfaces were faulty, passive_mcast_flush_send and related
functions ended in endless loop. This is now handled and if there is no
live interface, message is dropped.

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.

The recv_flush code is no longer necessary because of the miss_count_count
addition. It can in some cases lead to register corruption because of
interactions with -fstack-protector, the recursive nature of how this code
works, and interactions with the optimizer in some versions of gcc.

This change paves the way for eliminating a copy within the Infiniband
driver in the future by transferring responsibility for allocating and
freeing message buffers to the transport driver layer.
Tested under valgrind on a single-node cluster.

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.

most of the values in logsys.h are very useful for non logsys library
API users.
Allow to import them without sucking the whole lib.
