Summary of changes: AppleWin.cpp: Made dwCyclesThisFrame global -> g_dwCyclesThisFrame. CPU.cpp: Made InternalCpuExecute()'s nCyclesLeft static -> nInternalCyclesLeft. CPU.cpp: Added CpuGetCyclesThisFrame(). Memory.cpp: Added MemGet80Store(). Memory.cpp: Added MemReadFloatingBus(). Memory.cpp: Added MemReadFloatingBus(BYTE const highbit). Memory.cpp: Changed NullIo() to call MemReadFloatingBus(). Video.cpp: Added video scanner constants and VideoGetScannerAddress(bool* pbVblBar_OUT). Video.cpp: Changed VideoCheckVbl() to call VideoGetScannerAddress(). Various files: Replaced MemReturnRandomData() calls with MemReadFloatingBus().
