Metacat

make sure serial version is included or set on MN.update().

make sure to call lock() on the SM when updating rightsholder (like every other method that gets a lock object from HZ).

CN.search() id not implemented by metacat -- making that explicit and also testing for it.

first pass at DOI minting using the EZID service in mn.generateIdentifier()
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5755

for MN.update() we needed to pass the original pid, not the new pid

do not reject any schemes -- all handled the same at the moment.

simple autogen-based implementation of MN.generateIdentifier(). does not support DOIs, ARKs, etc. It does support including a fragment, returning an identifier like "<fragment>.2012113010215298206"

limit /log and /object calls to configurable maximum count for paging. defaults to existing Metacat value of 7000

no need to mark SM as archived now that DocumentImpl.delete() does it.

In migrating to Hazelcast 2.4.x, replace deprecated methods. Use Hazelcast.newHazelcastInstance() rather than Hazelcast.init(). For other deprecated static methods, use the HazelcastInstance equivalent calls.
