* Moved exported ModItemInMarc from C4::Biblio to
C4::Items and renamed to _replace_item_field_in_biblio.
Function is now private and is not exported, as
ModItem is now the sole entry point for updating
an item record.
* Replaced calls to ModItemInMarc in C4::Circulation
with appropriate ModItem calls.
