Make string table functions that aren't used outside of string.c static.

Store the loaded refcount in the string table.

wined3d: Actually use the calculated mipmap surface sizes in IWineD3DDeviceImpl_CreateVolumeTexture.

SND_PCM_ASYNC was needed to get asynchronous callbacks, but they are
not used any more, so remove the code.
