Metacat

move DocInfo parsing into utilities project so that it can be used by Morpho as well as Metacat.

use default count = 1000 for CN.listObjects rather than -1 (because now -1 will cause an SQL error)

default replicaStatus to true for the CN.listObject call

make sure to call lock() on the SM when updating rightsholder (like every other method that gets a lock object from HZ).

CN.search() id not implemented by metacat -- making that explicit and also testing for it.

default replicaStatus (aka "show replicas in results") to true rather than false

add debug statements for listObject slice debugging

Do not set headers until response is ready to send (5756)

use dual query for query slicing - one for count, another for the actual records when requested.
https://redmine.dataone.org/issues/3065

get total (or subtotal when non-slicing params are present) count as a separate query from the field selection query.
