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.

Add a new object called totem.interface.dynamic to allow creation/deletion
of new child objects using the corosync-objctl utility:
to add new member:
linux# corosync-objctl -c totem.interface.dynamic.10-211-55-12
to delete an existing member:
linux# corosync-objctl -d totem.interface.dynamic.10-211-55-12
Corosync will dynamically add these members to the configuration and start
communicating with those nodes.

This reverts commit 1a7b7a39f4.
Reversion is needed to remove overflow of receive buffers and dropping
messages.

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.

Set the recv buffer to a large size and the send buffer to a large size to
allow the kernel to store more messages before dropping messages.

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.
