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.
Add method to set and get typed objects from the context. This can
be used to pass around context objects between modules without having
to register them.
Don't pass pw_properties around when we simply need to pass around
config info, only use pw_properties when used to construct an object
that keeps the properties.
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.
