Bug 7614: Check transfer limit in CanBookBeReserved and CanItemBeReserved

This patch adds $branchcode_to parameter to CanBookBeReserved and
CanItemBeReserved. It represents the pickup location for the hold. This patch
checks if the library is configured to be a pickup location (see Bug 7534), and
also if the item can be transferred into the given library (see Bug 18072).

To test:
1. prove t/db_dependent/Holds.t
