Bug fix 3409 : Adding an internal function to C4::Circulation

Bug fix 3409 : Adding an internal function to C4::Circulation

This patch add the use of CircControl and HomeOrHoldingBranch for return and transfert rules.
* ItemHomeLibrary goes to item{HomeOrHoldingBranch}
* PatronLibrary goes to the borrower library
* PickupLibrary depends where the items was checked out, and the actual library.

This add a little improvment that does not re-request each time the circcontrol syspref.
