Sometimes calling xyz_finilize() within a dispatch would
cause a crash because the qb_ipcc_disconnect actually
disconnects immediatly and frees it't memory. whereas
the corosync structure is reference counted. So this
makes use of the reference counting to only call
qb_ipcc_disconnect when it is fully dereferenced.

Add missing option for dispatch, which fills gap in combination of
block/nonblock and one/all dispatch types. New type doesn't mask
CS_ERR_TRY_AGAIN, and it means "no message was processed".

the only user of those obsoleted defines is dlm master (already ported)
to use CS_ and cmirror (that needs full porting to new corosync either way).

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.

If we don't care about the return value then typecase the return
value to void.
Else do something useful with the return value.

module doesn't provide quorum itself, merely a framework for setting and
querying it. I envisage YKD plugging into this rather than straight into
sync() eventually.
I've plugged this into the sync() routines rather than replacing them so
that quorum is itself a VSF, rather than a replacement - I'm not sure if
that is best or not. Opinions are welcome.
I've added an extra enum member to the service_handler so that we can
send IPC messages when the cluster isn't quorate. This will default to
NO (as now) but allows us to query and set quorum when we don't have it
.. a useful feature !
