>This patch adds above routes for checking anonymous item availability. Patron
>status is not checked.
>
>The returned data is for example:
>{
>  "checkout": {
>     "available": false,
>     "description": ["onloan"],
>     "expected_available": "2016-07-13"
>  },
>  "hold": {
>     "available": true,
>     "description": [],
>     "expected_available": null
>  },
>  "local_use": {
>     "available": false,
>     "description": ["onloan"],
>     "expected_available": "2016-07-13"
>  },
>  "onsite_checkout": {
>     "available": false,
>     "description": ["onsite_checkouts_disabled"],
>     "expected_available": null
>  },
>  "hold_queue_length": 1,
>  + some basic item information on locations, bib/bib(item)numbers etc.
>}
>
>Possible values in availability description are an empty array and any of:
>"onloan", "reserved", "damaged", "withdrawn", "itemlost", "restricted",
>"notforloan", "ordered". (+"onsite_checkouts_disabled" for onsite_checkout)
>
>To test:
>1. Apply patch and run minifySwagger.pl
>   perl misc/devel/minifySwagger.pl -s api/v1/swagger/swagger.json -d api/v1/swagger
>2. Play around with an item. Place a hold on it, checkout, set it damaged etc.
>3. Make GET requests to /api/v1/availability/items?itemnumber=YYY, where
>   YYY is an existing itemnumber. You can also try with biblionumber=XXX
>   query parameter, where XXX is an existing biblionumber.
>4. Check that the availability statuses are correct and that availability
>   description lists the appropriate status for unavailability.
>5. Repeat steps 1-3 until you are confident the route works as expected.
>6. Run the following tests:
>   - t/Koha/Item/Availability.t
>   - t/db_dependent/Items.t
>   - t/db_dependent/api/v1/availability.t
