Metacat

Added DOI generation to the 2.0.0 upgrade process. To succeed, this script must be run on a fresh 2.0.0 database, or on a 1.9.5 version database, as those are the only ways to get the needed foreign keys to be marked as deferrable. The identifier conversion must be turned on by setting correct properties in metacat.properties. See the comments in GenerateGlobalIdentifiers for details. By default, conversion is set to false in the properties file. If you want to convert an instance to use DOIs, be sure to set metacat.properties up BEFORE running through the Metacat configuration and database upgrade.

Use the Collections class from java.util.

-generate system meta for all docids, even those not originating on the server (replicas from the past)
-generate ORE docs and download remote data only for those documents that originated on this server being upgraded.

refactor generate system meta loop to the factory class -- to be reused in sysmeta and ORE generation

do NOT generate ORE maps or download data when we do the initial System Metadata generation -- this is deferred until D1 registration.

make more generic so that a custom list of IDs can be passed in.

insert OR update system metadata -- no need to do an update right after initial insert...

call the System Metadata generator during upgrade to 2.0.0

In IdentifierManager.updateSystemMetadata(), add a check for invalid system metadata (fields that throw a NullPointerException on access) to ensure that system metadata is populated correctly. Updated calling classes to handle the exception.

only delete replicated data files (server_location != 1)
