Calendars can be configured in a way that all days are closed.
The simplest way to do that is to configure a repeatable holiday for
every day of the week.
With such calendars, searching for an open day will literally take
forever.
This patch sets a hard limit on how many iterations are allowed before
giving up. This limit is set to the arbitrary value of 5000, which
should be large enough to be able to consider there is no open days if
we haven't found any with that many iterations, and small enough to
allow the loop to end quickly
Test plan:
1. Set system preference 'useDaysMode' to 'Use the calendar to push the
due date to the next open day' ('Datedue'). Make sure the existing
circulation rules do not conflict with that setting.
2. Browse to Tools » Calendar
3. Set every day of the week to "Holiday repeated every same day of the
week"
4. Issue an item to a patron
5. Check the box and select 'Renew selected items'
6. The renewal should fail pretty quickly
