hdb has some expense and is not necessary in the totempg.so runtime. This
patch removes the dependence on hdb and instead uses a direct pointer.

This API allows totem to operate as a multithreaded library. Performance is
better without threads but some library users may only have multithreaded
systems. In the corosync case where we have removed threads, this reduces
cpu utilization by ~10% by removing about 50% of the mutex lock and unlock calls
that occur during typical operation. Since the latest corosync is nearly
thread free, there is no need for mutex operations.

In a 10-node cluster where all nodes are booting up and starting corosync
at the same time, sometimes during this process corosync detects a node as
leaving and rejoining the cluster.
Occasionally the downlist that gets picked contains the local node. When the
local node sends leave events for the downlist (including itself), it sets
its cpd state to CPD_STATE_UNJOINED and clears the cpd->group_name. This
means it no longer sends CPG events to the CPG client.

Ring ID was being displayed both as hex and decimal in places. Update so
it's displayed consistently (I chose hex) to make debugging easier.

As a corosync-newbie it can be hard to bridge the gap between where a
particular message is sent and where the receive handler processes it,
and vice versa.
