This removes all query methods and replaces them by a single one that
returns a dictionary. Not only does this allow querying multiple
attributes at once, it is also more extensible, as the previous
attributes were specific to file URLs. file: [e74205bb71] check-in: [34fe205b84] user: js, branch: trunk, size: 2742 [annotate] [blame] [check-ins using] [diff]

Instead, explicitly declare them, as OF_ASSUME_NONNULL_{BEGIN,END} does
not apply to implicit return types. This means that after this commit,
all init methods have a nonnull return type, as they should have. file: [2cf6faae58] check-in: [2f4e0df8be] user: js, branch: trunk, size: 2699 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [f6db7d17ce] check-in: [4af49a13c3] user: js, branch: trunk, size: 2546 [annotate] [blame] [check-ins using] [diff]

This changes retaining behavior, meaning properties are not returned
retained and autoreleased anymore, so a property returned from a getter
now needs to be manually retained and autoreleased before calling the
setter. However, this is rarely the case and not using atomic improves
performance. file: [f9eca6d772] check-in: [0a73af49f0] user: js, branch: trunk, size: 2494 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [c3627ed7f5] check-in: [44f45c2e35] user: js, branch: trunk, size: 2483 [annotate] [blame] [check-ins using] [diff]

No support for paths and auto-wrapping yet.

Also, no classes like OFDictionary override it yet. file: [62c355b2c5] check-in: [3ad1f2b268] user: js, branch: trunk, size: 2477 [annotate] [blame] [check-ins using]
