Log is attached.
added a parameter to S_StopChannel to trigger a mutex lock, this fixes
crashes in the SDL audio callback when S_StopChannel clears fields while
they are being used in the mixer (this mostly crashed on level changes),
the mutex lock itself is done simply by calling SndSys_LockRenderBuffer
