corosync internal theory of operation is that without a quorum provider
the cluster is always quorate. This is fine for membership free clusters
but it does pose a problem for applications that need membership and
"real" quorum.
this change add quorum_type to quorum_initialize call to return QUORUM_FREE
or QUORUM_SET. Applications can then make their own decisions to error out
or continue operating.
The only other way to know if a quorum provider is enabled/configured is
to poke at confdb/objdb, but adds an unnecessary burden to applications
that really don't need to use an entire library for a boolean value.

From the strcpy(3) man page, the following warning is given:
The strncpy() function is similar, except that at most n bytes of src
are copied. Warning: If there is no null byte among the first n bytes
of src, the string placed in dest will not be null-terminated.
The current corosync code base does not take this warning into account
when using strncpy, potentially resulting in non-null terminated strings.

When building corosync against older libraries already installed on the system,
the corosync-notifyd application uses the wrong Makefile.am commands. This
results in the SNMPLIBS (which includes -L/usr/lib64) coming before the proper
LDADD flags. The result is an inability to compile on an already existing
installation.

This is to send dbus events on major cluster events:
- membership changes
- application connect/dissconnet from corosync
- quorum changes
dbus events can then be converted into snmp traps by foghorn or
corosync-notifyd can be run to directly send snmp traps.
