Marcel de Rooy 3f73f9228b Bug 9105: Second housekeeping followup
Removing some unused variables.
Restoring timeout parameter that was only used in cataloging.
Restoring copyrightdate and editionstatement in row data for template.
Small adjustment at the end of the while loop with template vars.

Discovered while doing so, that the paging feature needs some further corrections; will propose a patch under a separate report.

=head1 NAME
C4::Breeding : module to add biblios to import_records via
the breeding/reservoir API.
=head1 SYNOPSIS
use C4::Scan;
&ImportBreeding($marcrecords,$overwrite_biblio,$filename,$z3950random,$batch_type);
C<$marcrecord> => the MARC::Record
C<$overwrite_biblio> => if set to 1 a biblio with the same ISBN will be overwritted.
if set to 0 a biblio with the same isbn will be ignored (the previous will be kept)
if set to -1 the biblio will be added anyway (more than 1 biblio with the same ISBN
possible in the breeding
C<$encoding> => USMARC
or UNIMARC. used for char_decoding.
If not present, the parameter marcflavour is used instead
C<$z3950random> => the random value created during a z3950 search result.
=head1 DESCRIPTION
ImportBreeding import MARC records in the reservoir (import_records/import_batches tables).
the records can be properly encoded or not, we try to reencode them in utf-8 if needed.
works perfectly with BNF server, that sends UNIMARC latin1 records. Should work with other servers too.

=head2 Z3950Search
Z3950Search($pars, $template);
Parameters for Z3950 search are all passed via the $pars hash. It may contain isbn, title, author, dewey, subject, lccall, controlnumber, stdid, srchany.
Also it should contain an arrayref id that points to a list of id's of the z3950 targets to be queried (see z3950servers table).
This code is used in acqui/z3950_search and cataloging/z3950_search.
The second parameter $template is a Template object. The routine uses this parameter to store the found values into the template.
