Metacat

add simple test for the IndexEventDAO class -- adding, removing, listing events in the DB table. https://projects.ecoinformatics.org/ecoinfo/issues/5944

upgrade to Metacat 2.1.0 on the trunk. This includes a new index_event table for storing indexing events that need to be reprocessed. https://projects.ecoinformatics.org/ecoinfo/issues/5944

stub for storing IndexEvent objects in Metacat (from metacat-index processing). https://projects.ecoinformatics.org/ecoinfo/issues/5944

do not force a get() during refresh (causing EML-defined data access rules to be lost when inserting EML docs about data files). note that this reverses a change that was meant to trigger indexing, but now we are using a new queue to share index events with metacat-index and so should not be necessary.

do not use tmp file to return an inputstream on read() operations - just read from the file we already have. https://projects.ecoinformatics.org/ecoinfo/issues/6009

use standard File.createTempFile() method for uploaded data files and delete them when we are done with them. https://projects.ecoinformatics.org/ecoinfo/issues/6008

correct regex for whitespace in D1 identifier.

use an independent ISet<SystemMetadata> structure to communicate objects that should be indexed by metacat-index. https://projects.ecoinformatics.org/ecoinfo/issues/5943

do not create solr-home if there is no template to compy into that directory (need to be able to create it later if/when someone decides to use and deploy metacat-index). https://projects.ecoinformatics.org/ecoinfo/issues/6006

do not attempt to copy solr-home template from metacat-index webapp if it does not exist. This would be in cases where metacat-index is not deployed. https://projects.ecoinformatics.org/ecoinfo/issues/6006
