Make a new method that can take a local node and run it in a remote
pipeline. This basically replaces all functionality of the streams
and more.
Add 2 examples for exporting a sink and a v4l2 node
Make some more things const
Cleanups
Make it possible to do things when the node needs scheduling. The
default node will schedule the local pipeline but the remote node might
also schedule the remote pipeline.
Fix docs
Add some more versions to interfaces
Make types for the various proxy object + inline methods that does type
checking and create proxys etc.
Set owner client of client-nodes in the properties
Pass type to bind to in create-node
Don't place global id in the info structs
Improve registration of marshal functions
Pass more types around as ids
Add hooks that contain protocol specific interfaces that can be used
to extend the protocol. This makes it possible to add new interfaces
to the protocol and implement the protocol specific data transport.
Move these protocol specific extension to the extensions directory.
Remove context and extensions, make client API also use the core.
Make a new pw_remote object that keeps connections with remote
instances.
Remove introspection API, it's just as easy to connect to the registry
and get updates like that.
Expand the protocol a little to make it useful for making listeners
and connections.
Move protocol specific connection to the module. Make some new
convenience methods.
Make a factory to create nodes from spa objects
Add an example of a local pipeline displaying a v4l2 source.
Rework the node and port API so that other implementations can be used
than the spa_node. The plan is to morph this into the stream and
context API.
Rework the graph API a little so that init + add is separated.
Make real spa_graph nodes and ports and schedule those. This makes
it possible to add explicit tee and mixers in the real graph.
Rework the way we add and remove ports and nodes from the graph.
Remove confusing pw_port_link and merge core with pw_link_new()
Move scheduling in separate files, add some more graph-schedulers.
Trigger initialized after we created the node global so that we
can get its id.
Add the server side node_id for the stream in the stream struct.
Change the transport function to pass the node_id to the client.
Small cleanups
