Refactoring qatomic_windows.h
Consolidated Interlocked* declarations and API implementation through macro hackery, (hopefully) for improved readability and maintainability. Fixes anti-aliasing warnings with MinGW in qatomic_windows.h. Gcc builds now use inline assembly for atomic operations, instead of relying on Interlocked* functions which aren't consistently declared across implementations (mingw32, mingw-w64, wine... others?). Drops support for VC 6 and MetroWerks. Reviewed-by: Thiago Macieira
