Kill cocoa::deriveNamingConvention and cocoa::followsFundamentalRule. They are now just simple wrappers around method families, and method decls can cache method family lookups. Also, no one is using them right now.

The one difference between ObjCMethodDecl::getMethodFamily and Selector::getMethodFamily is that the former will do some additional sanity checking, and since CoreFoundation types don't look like Objective-C objects, an otherwise interesting method will get a method family of OMF_None. Future clients that use method families should consider how they want to handle CF types.

-// The "fundamental rule" for naming conventions of methods:

-//  http://developer.apple.com/documentation/Cocoa/Conceptual/
-//     MemoryMgmt/Tasks/MemoryManagementRules.html
-//
-// "You take ownership of an object if you create it using a method whose name
-//  begins with "alloc" or "new" or contains "copy" (for example, alloc,
-//  newObject, or mutableCopy), or if you send it a retain message. You are
-//  responsible for relinquishing ownership of objects you own using release
-//  or autorelease. Any other time you receive an object, you must
