Corosync Tie Breaker Enhancement
The auto_tie_breaker quorum feature of Corosync has been enhanced to provide options for more flexible configuration and modification of tie breaker nodes. Users can now select a list of nodes that will retain quorum in case of an even cluster split, or choose that quorum will be retained by the node with the lowest node ID or the highest node ID.

The object is unlinked at quorum_unregister_callback. However,
it is not freed at the function.

votequorum: Add extended options to auto_tie_breaker
This patch adds more flexibility to the auto_tie_breaker feature of
votequorum. With this, not only can the lowest nodeid be used as
a tie breaker, but also the highest, or a node from a nominated list.
If there is a list of nodes, the first node in the list that was not
part of the previous partition is used. This allows the user to
specify a preferred set of nodes but prevents a split-brain if the
cluster divides evenly with a node in each half.

votequorum: Properly initialize atb and atb_string
icmap_get_* behavior is to NOT modify passed variable when it doesn't
success. So we must initialize variable before icmap_get_* call.
