Issue Description:

IOKit's kIOReturn* error codes (declared in iokit/IOKit/IOReturn.h) are not imported to Swift, presumably because they're defined in terms of a macro. For example:

#define iokit_common_err(return)          (sys_iokit|sub_iokit_common|return)
...
#define kIOReturnNoMemory        iokit_common_err(0x2bd) // can't allocate memory

The Objective-C IOBluetooth API uses these error codes, so they're useful even outside of IOKit development. Perhaps they could be re-defined in Swift, much like Mach Error.

The overlay files are owned by the framework owners at Apple, even though they need to be distributed with Swift. I'll try to get in touch with someone from IOKit.

Okay, I'd be happy to send a pull request otherwise.

The IOKit people say they're fine with an overlay solution, so please feel free to send that pull request! (You can assign it directly to me.)
