Metacat

Add in Darwin Core schema support into xml_catalog, and insert it on upgrade as well. The schemas are cached in lib/schema/dwc, and Matt and Ben noted that the tdwg_basetypes.xsd and tdwg_dwctypes.xsd are part of the same namespace, but are xs:include'd rather than imported via namespace.

In lieu of pulling schemas from URL endpoints for dataONE, Darwin core, and Dryad, we're caching them in Metacat so we have stable copies. Remove the ant targets used to pull them.

Add the three Darwin Core schemas required by the Dryad Metadata Profile (via imports).

include a few tests for isEqual method. https://projects.ecoinformatics.org/ecoinfo/issues/6407

Add cached versions of the DataONE, Dryad, Dublin core, and Darwin Core schemas to Metacat. Remove schemaLocation attributes so that we rely on the local catalog and don't use (potentially changing) URL endpoints.

Use client.MetacatClient instance for all metacat api calls

Test syncing of access policies when updated with legacy metacat api

Change isEqual to private so it can be used by test suite

Add DataONE, Dublin Core, and Dryad schemas during the 2.4.0 upgrade, and be sure to remove the appropriate entries before inserting to avoid duplicate rows.

Add schema support for the DataONE, dublin Core, and Dryad schemas. Schemas get downloaded into lib/schema priior to jar and dist targets, and get loaded into xml_catalog on installation.
