The "default" access is used for normal clients, in the use case where
Pipewire server will not assign permissions itself but leaves it to the
session manager. In this use case only session manager has
"unrestricted".
Make "default" equal to "unrestricted" in the default access
configuration.
This patch also moves nested configuration objects that are not considered
settings from the wireplumber.settings section to its own configuration
section (eg the rules array, the spa plugin properties, etc...). This allows
those objects to be merged with other same sections defined in other files.
* client: Logic that deals with configuring clients (basically, permissions)
* device: Anyhing that that deals with configuring devices (profiles, routes, ...)
* node: Anything that deals with node objects: configuring nodes, changing
their state, their properties and also creating new nodes (but NOT linking them)
* linking: All the logic for creating links between nodes (and obviously,
deciding which links to create)
* monitors: Scripts that deal with hardware subsystems, mainly monitoring
hardware changes and reflecting them on pipewire
* default-nodes: All the logic for selecting the default sinks and sources
