reduce bib fetches during search and OPAC display

Speed up bib search and OPAC bib display, especially
when the XSLT OPAC results and details display sysprefs are
ON, by passing an existing MARC::Record object to three
functions:

C4::Biblio::get_biblio_authorised_values()
C4::XSLT::XSLTParse4Display()
C4::XSLT::transformMARCXML4XSLT (internal)

These functions previously fetched the bib from the
database, incurring the cost of DB retrieval and MARCXML
parsing even though client code already had a
MARC::Record object available.
