I've gone through and removed traces of the old method.

The only thing left before this can be cleared is for there to be a better
example in the usage comments for CFCastStrict. The current example uses the old
method as follows:

base::mac::CFCastStrict<CFStringRef>(base::mac::GetValueFromDictionary(some_dict,
CFSTR("a_key"), CFStringGetTypeID()));

Now that the new method handles the cast, what would be a better example to use?
I'm going to have a look through the Apple CF docs for methods that return
CFTypeRefs but if you have a good example I'm all ears.

This CL is currently running through the trybots.
