[clang-tidy ObjC] [3/3] New check objc-forbidden-subclassing
Summary:
This is part 3 of 3 of a series of changes to improve Objective-C
linting in clang-tidy.
This adds a new clang-tidy check `objc-forbidden-subclassing` which
ensures clients do not create subclasses of Objective-C classes which
are not designed to be subclassed.
(Note that for code under your control, you should use
__attribute__((objc_subclassing_restricted)) instead -- this
is intended for third-party APIs which cannot be modified.)
By default, the following classes (which are publicly documented
as not supporting subclassing) are forbidden from subclassing:
ABNewPersonViewController
ABPeoplePickerNavigationController
ABPersonViewController
ABUnknownPersonViewController
NSHashTable
NSMapTable
NSPointerArray
NSPointerFunctions
NSTimer
UIActionSheet
UIAlertView
UIImagePickerController
UITextInputMode
UIWebView
Clients can set a CheckOption
`objc-forbidden-subclassing.ClassNames` to a semicolon-separated
list of class names, which overrides this list.
Test Plan: `ninja check-clang-tools`
