Metacat

Fix a minor bug in listObjects() where total was set incorrectly when total was set incorrectly when count=0. The definition of total in the D1 architecture docs says 'The total number of entries in the source list from which the slice was extracted.' With count=0, we assume the total is the total count from the entire object store. Needs testing.

remove empty package

rollback the delete() when there is an error performing part of it -- don't want to end up with partial delete.

use Identifier object not String when retrieving SM from the HZ map to set archived during delete()

for MN.update() we needed to pass the original pid, not the new pid

do not reject any schemes -- all handled the same at the moment.

simple autogen-based implementation of MN.generateIdentifier(). does not support DOIs, ARKs, etc. It does support including a fragment, returning an identifier like "<fragment>.2012113010215298206"

add link for reference on how to do record limits in oracle

limit /log and /object calls to configurable maximum count for paging. defaults to existing Metacat value of 7000

use RDBMS-specific features to limit the resultset for paging the object list -- postgres and oracle have implementations. we don''t really support mssql so I skipped that one.
