Subject: [PATCH] LP#849143 fix some gaps in bib record merging
Tweaks asset.merge_record_assets such that it considers acquisition line items and user requests, serial subscriptions, booking resource types, biblio monograph parts, and biblio peer bib copy maps. I'm not handling vandelay.queued_record.imported_as or any other vandelay tables, but we may wish to do that too. We're also leaving acq.acq_lineitem_history alone.
