Bug 12063: Change date calculation for reserve expiration to skip all holiday

This patch makes koha automatically set expiration date when reserves become
waitting. Also it adds a new syspref "ExcludeHolidaysFromMaxPickUpDelay" that allows to
take holidays into account while calculating expiration date.

Test plan:

  - Install this patch and run updatedatabase.pl script,
  - allow ExpireReservesMaxPickUpDelay in system preferences,
  - set ReservesMaxPickUpDelay to 5.

  - Place an hold on a checked out item and check in this item:
    The hold's expiration date should be today + 5.

  - Allow ExcludeHolidaysFromMaxPickUpDelay in system preferences,
  - add holiday during this pickup delay period,
  - Create a new hold and make it comes waitting:
    The hold's expiration date should be today + 5 + number of closed
    day(s).

Also:
  - Check that ExpireReservesOnHolidays syspref works again
    without ExcludeHolidaysFromMaxPickUpDelay.
  - Check that cancel fees apply again if wanted.
