Added DirectSound audio backend This commit adds the DirectSound audio backend, which is a modified version of core/oslib/ds_audiostream.cpp. Porting this was a bit tricky, since ds_audiostream.cpp defined 3 extern functions that the other backends didn't have: * bool os_IsAudioBuffered(); * bool os_IsAudioBufferedLots(); * int os_getusedSamples(); I came to the conclusion that these methods are obsolete since they are only used core/windows/winmain.cpp in the function void os_wait_cycl(u32 cycl) - which is used nowhere. Thus, I removed os_wait_cycl and the headers of the three functions in core/oslib/oslib.h. I also removed the functions themselves (except for int os_getusedSamples(), which is still used inside the directsound backend, but can safely declared static for that purpose). The DirectSound backend will be included during compilation if HOST_OS is OS_WINDOWS.
