[PATCH 0/1] MR9231: winemac.drv: Include Carbon.h in macdrv_cocoa.h and remove duplicate definitions.

[Brendan Shanks (＠bshanks)]

Include Carbon.h in macdrv_cocoa.h, this allows duplicate definitions to be removed from keyboard.c. The `#ifdef __i386__` isn't strictly needed, but marks them to be removed when we stop supporting i386 (likely sooner than later).
