The proxy API is the one that we would like to expose for applications
and the other API is used internally when implementing modules or
factories.
The current pw_core object is really a context for all objects so
name it that way. It also makes it possible to rename pw_core_proxy
to pw_proxy later.
Create an endpoint link object when linking endpoints. Keep track
of the links in the endpoint_link and cleanup when they are all
gone.
Improve properties on session objects.
pulseaudio card is mapped to device
pulseaudio sink/source is mapped to an endpoint
prepare to map streams to card profiles
Add Route param to implement the endpoint routing later (ports)
Create an alsa endpoint for each device
Create one stream for each endpoint (Playback/Capture)
Implement create_link on the endpoint. The idea is to call
create link on the peer endpoint to complete the link. Remove
create_link on the session.
Add stream-monitor to turn pw_stream nodes into endpoints
Add a policy manager that tries to link endpoints
Use enum pw_direction for the endpoint direction. We can use the
media_class to determine if this is a pw_stream or not but it should
not really matter, you can link any output to any input.
Add autoconnect property for endpoints to make the policy connect.
