The listeners are generally useful in spa, move it there and rename
to hooks. Implement loop hooks with it.
Fix some cleanup issues in stream and remote
Remove signals.
Rename callbacks -> events, use listeners to listen for events.
Callbacks are still used in spa for things you can listen to only
once.
Make it possible to add more permissions to an object than just visible
or not. Pass these permissions to the client. This way we can make a
difference between being able to see and read, modify or query an
object. More permissions can be added later when needed. Because the
permissions is set on the resource by the access control module, the
implementations can check if the right permission is set before doing
anything.
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.
