[swift-evolution] Rewrite imported C function signatures

[Carlos Rodríguez Domínguez]

Well, it might be both an external annotation on C code and something specific within swift. The first is interesting when you have access to the C source code, but the later is good if you either don’t have access to the C source code, or the code (swift, objective-c, C, etc.) is autogenerated by an external tool (for instance, CoreData tools).

Perhaps, with Swift 3 going Linux, with should expose the ability to annotate external code to the users? And enum importing could be a part of that.
