Objc Apple Runtime and constant strings

The plain and simple answer is because I forgot we had it. :slight_smile:

Thanks for the info on the magic constant, I will look into merging the
definitions and add some more documentation referencing the stuff you
mention tomorrow.

After a deeper look at both implementations, I have no opinon on which one should be keeped, and which one you can replace.
This choice is up to you.
When you merge them, I have some patches to add UTF16 string generation support, and also to add 64 bit arch support (the CFString structure has one more field in 64 bit runtime).
