Remove the parent_id from the global event. Remove the parent
and owner from the global object.
Use properties instead to mark parents and owners of objects.
Properties are easier to control for client exported objects and
usually a simple parent/child is not enough. For example, a client
exported node has the client as a parent but also the factory that
created the node.
Set the drained flag.
If the server calls us and we're out of buffers and the drained
flag is set, emit the drained signal.
Deactivate the node on disconnect.
Make sure we have no more pending process callbacks in the invoke
queue before when we pause.
When we do invoke from the loop thread, first process the pending
invoke items before handling ours. This can be used to sync the
invoke queue before cleanup.
Keep the output port buffers in a special mix info. They should
stay there even when the mix is removed and should only be cleared
explicitly with a NULL Format or 0 use_buffers.
When we destroy a proxy, mark it as zombie until the server removes
the id. This way we can still keep the id locked with a valid entry
and remove it later.
Implement per channel volume on channelmix. Extend control on stream to
take an array of values when possible.
Remove name argument from pw_node_new and pw_device_new. We can pass
this as a property instead.
Improve properties on nodes to more closely match what pulseaudio does.
Don't let the monitor do too much with the udev properties but let the
session manager set the description and icon-names.
Remove some change_mask flags for things that don't change in
introspect. Use the flags to mark changes in -cli and -monitor.
Use the channelVolume property to update the individual channel
volumes.
Update property values to match pulseaudio.
Handle the case where the number of channels changes. In pulse this
can normally never happen. Emit a remove and add of the node when
this happens as to not confuse pulse clients.
