Rework the metadata implementation without pw_properties to make
it easier to delete all subjects and implement the metadata API.
Remove metadata from all objects when they are destroyed.
Monitor the device reservation objects and mark the device available.
Don't select nodes from devices that are not available.
Acquire the device reservation when a device starts.
Release the device reservation when we suspend the device again.
Add a asprintf helper function that handles errors correctly.
Use this in places where we use asprintf to avoid warnings when we
don't check the return value.
While we are creating objects on the monitor connection, pause the
policy connection until we have completed a roundtrip and the global
id is bound to the new object.
This way, when we resume the policy connection, we can always find the
newly created and bound object. Without the pause, it's possible that
we receive the new global on the policy connection before we got the
bind reply on the monitor connection and then we would end up with 2
proxies that are not linked together correctly.
Fixes#204
Make it possible to run the session manager without endpoint
modules. Add a simple node policy that links nodes.
Move the session-manager implementation and startup of the
endpoint monitors to a separate module.
Handle async set_param on the device
Never free a proxy without the application doing a pw_proxy_destroy.
It's hard to use when proxies are freed randomly when the server
removes the ids. You have to add destroy notify to all proxies and
deal with the arbirary order in which proxies can be freed.
Instead notify the client of the remove and let it destroy the
proxies itself in the right order. This is in line with how wayland
handles proxies.
A pw_proxy_destroy() will now send a destroy to the server and mark
the proxy as a zombie, waiting for the remove_id confirmation and
then destroy the proxy.
A server remove_id will mark the proxy as removed and emits the
removed event. The app should then pw_proxy_destroy the proxy
to free it.
Leaks all proxies in the session manager because cleanup now needs
to be handled by the app correctly.
This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.
