[Openais] corosync trunk determine memb list when running in compatibility mode

When cross communicating with whitetank, we need to determine a list of
members for the syncv2 protocol to operate upon.  The reason is that the
syncv2 capable machines (ie: corosync in whitetank compat mode) may be
only a subset of the cluster when run with other openais whitetank
cluster members.

This patch sends determines the membership of the syncv2 members.  It
relies on the barrier functionality in the regular sync operation to
ensure that all syncv2 determination messages are received before
starting its operation.
