This patch removes the previously introduced private method by
converting the arrayref returns to ResultSets appropriately and inlining
the filter search queries.

-Checks if an item can be transferred to given libraries.
-
-This feature is controlled by two system preferences:
-UseBranchTransferLimits to enable / disable the feature
-BranchTransferLimitsType to use either an itemnumber or ccode as an identifier
-                         for setting the limitations
-
-Takes HASHref that can have the following parameters:
-    MANDATORY PARAMETERS:
-    $to   : Array of Koha::Libraries
-    OPTIONAL PARAMETERS:
-    $from : Koha::Library  # if not given, item holdingbranch
-                           # will be used instead
-
-Returns arry of Koha::Libraries that item can be transferred to $to_library and
-are pickup_locations
-
-If checking only one library please use $item->can_be_transferred.
