Bug 32496: Reduce unnecessary unblessings of objects in Circulation.pm

Refactor the most performance critical subroutines in Circulation.pm
to take objects instead of unblessed ones to reduce unnecessary
unblessings and generally clean up the code.

To test:

1) Ensure the following tests all pass:
