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. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@1266 fefdeb5f-60dc-0310-8127-8f9354f1896f
