ObjFW  Check-in [95830bf78b]

Overview
Comment:OFDate: Prepare for tagged pointers

This replaces all ivar accesses with calls to -[timeIntervalSince1970]
(except for initializers and -[timeIntervalSince1970] itself, which is
the only method accessing an ivar and will be overridden for tagged
pointers), returns a placeholder for +[alloc] and makes +[distantFuture]
and +[distantPast] singletons.
