068f5d5eef drop chunk argument from various drop() functions, since it doesn't make any sense if we want to guarantee always monotonously increasing read pointers; a couple of other fixes

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.

a621d90285 allow hooking into the process of creating playback streams. To implement this I modified the pa_sink_input_new() signature to take a pa_sink_input_new_data structure instead of direct arguments.
