emu20k1 has a native timer interrupt based on the audio clock, which is more accurate than the system timer (from the synchronization POV). This patch adds the code to handle this with multiple streams. The system timer is still used on emu20k2, and can be used also for emu20k1 easily by changing USE_SYSTEM_TIMER to 1 in cttimer.c.
