Metacat

check both previous and current data revisions when updating packages. https://projects.ecoinformatics.org/ecoinfo/issues/5647

avoid SQL errors when processing very old objects of type: "-//ecoinformatics.org//eml-access-2.0.0beta6//EN"

If the pathquery engine is disabled, the xml path index queue will be disabled as well.

If the xpath query is disabled, the query, squery and spatial_query action will be disabled as well.

Add code to throw an exception if the pathquery is not enabled.
We also need to disable building index if the pathquery is disabled.

use consistent file names and zip content names. Opted for "-" separator so that the zip writer does not remove the unique part of the filename. https://projects.ecoinformatics.org/ecoinfo/issues/6054

copy the original systemMetadata when publishing a revision in order to avoid overwriting the original values - the shared map is listening! https://projects.ecoinformatics.org/ecoinfo/issues/6014

include user's fullName when validating a session. also, allow cookie session to be used if not passed in directly as a parameter

Add code to modify the web.xml in metacat-index context if the metacat's name is not knb.

include filename in the package download, though we can;t really use the PID because of all the potential characters in it that are not valid for filesystems.
