Metacat

system metadata generation optionally skips entries that have already been generated (data size, checksum) but allows the latest EML that describes them to have the last word on object format

remove DML for parsing -- the D1 EML parser still uses DOM, so this may not be too big of a perfromance improvement

test harness for running system metadata generation outside of the upgrade process

include comment about KNB estimated time to run during upgrade:
Total time: 20 minutes 58 seconds

only attempt to update date-like nodedata values.

use "test" to exercise upgrade code on staging DB.

include generate system metadata upgrade in the success flag

more clean up - reuse prepared statement for data update

look up nodedata values first, then update each one - trying to avoid out of memory exception.

eliminate the cross product that occurred when updating xml_access with a join
