8389264d65 count corked streams per sink/source and make pa_sink_used_by() return only the number of streams that are not corked. Introduce pa_sink_linked_by() returning the number of streams connected at all. This will allow suspending of sinks/sources when all streams connected to a sink are corked.

3396b65f15 simplify rt loops a bit by moving more code into pa_rtpoll. It is now possible to attach "work" functions to a pa_rtpoll_item, which will be called in each loop iteration. This allows us to hide the message processing in the RT loops and to drop the seperate sink_input->process hooks. Basically, only the driver-specific code remains in the RT loops.

4d623f0d44 Lots of assorted minor cleanups and fixes: 
* s/disconnect/unlink/ at many places where it makes sense
* make "start_corked" a normal pa_sink_input/pa_source_output flag instead of a seperate boolean variable
* add generic process() function to pa_sink_input/pa_source_output vtable that can be used by streams to do some arbitrary processing in each rt loop iteration even the sink/source is suspended
* add detach()/attach() functions to pa_sink_input/pa_source_output vtable that are called when ever the rtpoll object of the event thread changes
* add suspend() functions to pa_sink_input/pa_source_output vtable which are called whenever the sink/source they are attached to suspends/resumes
* add PA_SINK_INIT/PA_SOURCE_INIT/PA_SINK_INPUT_INIT/PA_SINK_OUTPUT_INIT states to state machines which is active between _new() and _put()
* seperate _put() from _new() for pa_sink/pa_source
* add PA_SOURCE_OUTPUT_DONT_MOVE/PA_SINK_INPUT_DONT_MOVE flags
* make the pa_rtpoll object a property of pa_sink/pa_source to allow streams attached to them make use of it
* fix skipping over move_silence
* update module-pipe-source to make use of pa_rtpoll
* add pa_sink_skip() as optimization in cases where the actualy data returned by pa_sink_render() doesn't matter

0defdfb560 A lot of updates, all necessary to get the native protocol ported: 
* add an int64_t argument to pa_asyncmsgq because it is very difficult to pass 64 values otherwise
* simplify subclassing in pa_object
* s/drop/unlink/ at some places
* port the native protocol to the lock-free core (not tested, compiles fine)
* move synchronisation of playback streams into pa_sink_input
* add "start_corked" field to pa_sink_input_new_data
* allow casting of NULL values in pa_object

d210ebbb09 rework memory block management to be thread-safe and mostly lock-free. 
pa_memblock is now an opaque structure. Access to its fields is now done
through various accessor functions in a thread-safe manner.

pa_memblock_acquire() and pa_memblock_release() are now used to access the
attached audio data. Why? To allow safe manipulation of the memory pointer
maintained by the memory block. Internally _acquire() and _release() maintain a
reference counter. Please do not confuse this reference counter whith the one
maintained by pa_memblock_ref()/_unref()!

As a side effect this patch removes all direct usages of AO_t and replaces it
with pa_atomic_xxx based code.

This stuff needs some serious testing love. Especially if threads are actively
used.

0e436a6926 Rework memory management to allow shared memory data transfer. The central idea 
is to allocate all audio memory blocks from a per-process memory pool which is
available as read-only SHM segment to other local processes. Then, instead of
writing the actual audio data to the socket just write references to this
shared memory pool.

To work optimally all memory blocks should now be of type PA_MEMBLOCK_POOL or
PA_MEMBLOCK_POOL_EXTERNAL. The function pa_memblock_new() now generates memory
blocks of this type by default.
