Changes to improve speed of MARC bib and item
imports:
[1] Turn off autocommit and commit database
transactions in larger batches.
[2] Introduce a new C4::Biblio function (AddBiblioAndItems)
to combine AddBiblio and AddItems -- this is faster
because we are not parsing the MARC XML of the biblio
every time we add an item.
[3] Introduce FasterTransformMarcToKoha, which is much
faster than TransformMarcToKoha. The new version,
which will replace the old one once it has been
fully tested, scans through each field in the
MARC record just once, instead of potentially
dozens of times.
[4] Remove code in bulkmarcexport that moved the
item tags to separate MARC::Record objects.
