- Change meaning of special values of latency request: 0 -> "minimal latency, please"; (pa_usec_t)-1 -> "don't care"

Browse source 
- Remove "source" word from monitor source description
- Increase default tsched watermark to 20ms again
- For the first iteration after snd_pcm_start() halve the sleep time as workaround for USB devices with quick starts
