When the client is explicitly going to send reuse_buffer messages,
set the consumed buffer to INVALID so it doesn't automatically get
reused.
ASYNC is for when the node emits events to signal input and output it
has nothing to do with reuse_buffer
Remove weird PROCESS_INPUT code.
Add a PW property "pipewire.client.reuse". If set, the client-node
doesn't immediately reuse a buffer after sending
PW_CLIENT_NODE_MESSAGE_PROCESS_INPUT to the client. Instead, it waits
for reuse-buffer from the client. The SPA_GRAPH_NODE_FLAG_ASYNC is
used for this, together with adapted logic in process_input().
In stream.c, if the property is set, the handling of incoming buffers
for PW_DIRECTION_INPUT streams is changed. Each buffer has to be
recycled, so we make sure new_buffer is emitted for each intermediate
buffer, if buffer_id in the IO area has moved past some buffers.

For PW_DIRECTION_INPUT streams, set the used flag for buffers before
emitting new_buffer. This makes recycle_buffer() effective.

Handle reuse-buffer in output-port tee nodes and input-port mix
nodes. In both cases, reuse-buffer is forwarded to the input ports of
the tee/mix node.

using JSON for formats or properties is not a good idea because we can't
add more types like pointers, fd, rectangles without weird hacks. Our
PODs are more easy to parse and extend and now there is an easy way
to parse and create them as well.
Don't directly expose the state change methods. Only expose an activate
method for nodes that indicates if the node should be scheduled or not.
Let the link automatically negotiate two active nodes.
Make some defines for properties.
Use link property to make passive links. Passive links don't activate
the nodes.
Make sure the mainloop quits when quit is called before run.
Add an extra input and output node for remote nodes. We link this
node to all remote inputs and outputs to make it easier to use
the scheduler.
Improve scheduler debug
