f49df7a3b0 * Increase history set to 64 to simplify reduction of indexes 
* Decrease memory consumption a bit by using bitfields for some bools
* Rework reduction code
* Drop an unnessacary counter
* Before adding a new entry to the history, try to figure out if we already have an existing entry with the same x value and replace that. This fixes a division by zero
* Fix up input x for all functions, according to the time offset

76031df4a4 Big pile of interdependant changes: 
* Fix a deadlock when an asyncq overflows and an RT thread needed to wait until space became available again while the main thread was waiting for a operation to complete and thus didn't free any new items. Now, if the asyncq overflows, queue those items temporarily, and return immediately. Then, when the queue becomes writable again, flush it.
* Modify pa_thread_mq_init() to also set up pa_rtpoll events properly for the MQ
* Some more pa_bool_t'ization
* Unify more common code between alsa-sink and alsa-source
* The upper limit for the tsched watermark is max_use minus one frame
* make module-alsa-source work
* make the alsa modules use pa_alsa_build_pollfd() now
* fix detection of dB scale for alsa-source

e16a1987a3 - Change meaning of special values of latency request: 0 -> "minimal latency, please"; (pa_usec_t)-1 -> "don't care" 
- 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

62e7bc17c4 Big pile of dependant changes: 
* Change pa_memblockq to carry silence memchunk instead of memblock and adapt all users
* Add new call pa_sink_input_get_silence() to get the suitable silence block for a sink input
* Implement monitoring sources properly by adding a delay queue to even out rewinds
* Remove pa_{sink|source}_ping() becaused unnecessary these days and not used
* Fix naming of various rewind related functions. Downstream is now _request_rewind(), upstream is _process_rewind()
* Fix volume adjustments for a single stream in pa_sink_render()
* Properly handle prebuf-style buffer underruns in pa_sink_input
* Don't allow rewinding to more than the last underrun
* Rework default buffering metrics selection for native protocol
* New functions pa_memblockq_prebuf_active(), pa_memblockq_silence()
* add option "mixer_reset=" to module-alsa-sink
* Other cleanups
