Do not use dynamic types anymore. The reason is that it's difficult:
- to maintain a shared type database over a network.
- the extra overhead when translating between processes and for
maintaining the translation tables.
- race conditions in translating in RT-threads, this is a problem
because we want to make event streams.
We now have simple enums with types and extension points for all
types. This is also nicer to use in general.
We don't need the mapper anymore or pass strings around as types.
There is a parallel type info system to get more info about ids and
enums and their hierarchy. It can also be used for debugging.
Make it possible to assign an arbitary node as the port mixer.
Also remove dynamically added ports.
Improve negotiation and allocation on the mixer ports
Add some more SSE optimisations
Move float mixer from the audio dsp to the port
Remove pw_node_get_free_port() and do things more explicitly.
Handle mixer ports in client-node
Expose all ports as globals, linking is then done by specifying
the global id of the ports.
Add method to destroy objects. not much security on this one but
yet but it should allow priviledged clients to kill connections
and other clients etc.
Make events on the global object. Implement the bind with the event,
handle destroy of the globals.
Add link properties
Use append to preserve the order.
Don't pass around the client object but keep track of the current
client in the core object. This way we don't need to add a client
argument to functions and can check security when needed.
Pass client to some core functions to make it possible to check
permissions when iterating globals.
Check permissions of factory before using it.
Check permissions in link factory, only allow linking of nodes we can
see.
Check permissions in the autolink module, only try to link to nodes
we can see.
Make client permissions update behave like an atomic update of an
unordered set of permissions, which is perhaps a bit more intuitive.
Add properties to global objects to make it easier to select what
nodes and objects to bind too. They can also be used to implement
permissions on the globals based on properties.
Add more error handling in _register.
Make more functions return a result code.
Make a separate pw_module_register, like all other objects.
Make a link factory and use create-object to make links. That way
we can have different kinds of links based on the factory and we
can also hide the factory when link creation should be blocked.
