Bug 9823: Refactor return from GetReservesFromBiblionumber

The return from GetReservesFromBiblionumber contains an unnecessary
extra variable. In scalar context an array returns its element count.
Maintaining a separate count can lead to unforeseen bugs
and imposes ugly constructions on the subroutine's users.

Remove the useless count variable from the return

This patch also changes the parameters: now the routine takes a hashref.

Placed biblio holds, future holds and item holds. Works as expected.
Tested Holds.t and Reserves.t. Pass.
Tested /cgi-bin/koha/ilsdi.pl?service=GetRecords&id=999 with two holds on
one item. Fine.
C4/SIP/ILS/Item.pm: Looked for "whatever" and "arrayref" and could not find
them anymore. Looks good.
Handled a few unneeded calls in QA follow-up.
Left only one point to-do for serials/routing-preview.pl. See Bugzilla.

Bug 9823: QA follow-up for GetReservesFromBiblionumber calls

The template params holds and holdcount are not used in the ISBD template.
Removed the associated code from catalogue/ISBDdetail.pl.
Same applies for catalogue/MARCdetail.pl and labeledMARCdetail.pl.
Same applies also for catalogue/imageviewer.pl.
Same applies also for catalogue/moredetail.pl.

In catalogue detail.tt only the number of holds is used. Removed the code
that passed the holds array to the template.

For consistency opac-detail should also incorporate future holds into its
holds count; added the all_dates parameter for that reason.

The Reserves module is no longer needed in moredetail. Removed it. Checked
the other scripts also.
