LP#1619703 Transfer ACQ lineitem to bib API

New open-ils.acq API call for transfering a lineitem and its assets
to a new bib record.

Any asset.call_number's created from the lineitem are migrated to the
new target bib record.

Any monograph parts linked to copies created from the lineitem are
duplicated (if need) on the target bib record and part copy maps are
modified to use the new parts.

API: open-ils.acq.lineitem.transfer_to_bib(auth, li_id, target_bib_id)
