This patch changes the GetCOinsBiblio subroutine to take a MARC record object
(as returned from GetMarcBiblio) instead of a biblionumber. The first thing the subroutine
did was GetMarcBiblio, and the $biblionumber passed was never used again.
This subroutine was only used 3 places: opac/opac-search.pl, opac/opac-detail.pl,
and C4/VirtualShelves/Page.pm. In the first and last cases, it was used in a loop.
In the last two cases, a call to GetMarcBiblio had already been done. This is expensive, and
we were doing it twice per record.
For opac/opac-search.pl, the call to GetMarcBiblio was moved to just outside GetCOinSBiblio;
this will not change the performance at all. But for opac/opac-detail.pl and C4/VirtualShelves/Page.pm,
a redudant call to GetMarcBiblio is now avoided.
To Test:
1. Enable COinSinOPACResults in system preferences. Perform a search in the OPAC.
Verify that the COinS spans are showing up
2. View the detail record of one of the returned items. Confirm that the COinS span exists on the detail page.
3. View a list in the OPAC. Confirm that COinS spans are still showing up
