- deprecate autoload stuff

- allow setting of the requested latency of a sink input/source output before _put() is called
- allow sinks/sources to have a "minimal" latency which applies to all requested latencies by sink inputs/source outputs
- add new client library flags PA_STREAM_ADJUST_LATENCY, PA_STREAM_START_MUTED
- allow client library to fill in 0 to buffer_attr fields
- update module-alsa-source following module-alsa-sink
- other cleanups and fixes
