resource: improve error handling

Browse source 
Make some more varargs error functions
Make pw_resource_error always just send the error to the resource id.
Make sure we send errors to the right destination.
Add proxy error event and emit it when the core finds an error for
the given proxy id.
The client error is supposed to be sent to all resources of a client
for the given global.
