Bug 35641: Reduce DB lookups when sending a list of barcodes to inventory

Browse source 
This patch does three things:
1 - Removes a specific query for withdrawn status of each item scanned - we can use the withdrawn field
2 - Removes a specific query for checkouts on each item scanned - we can use the onloan field
    a - additionally we don't need to fetch the checkout as we check it in to the homebranch,
    this is likely incorrect - we should use the current branch, but I preserve behavior for now
3 - Fetches the items ahead of time and builds a hash based on barcode, reduces DB lookups, may raise memory usage

To test:
1 - Checkout some items
2 - Withdraw some items
3 - Generate a lsit of barcodes including some checked out items and some withdrawn items
4 - Enter that list of barcodes into inventory tool
5 - Note your results
6 - Apply patch
7 - Issue the items again
8 - Repeat inventory
9 - Confirm results are the same as before patch
