devlink: introduce object and nested devlink relationship infra It is a bit tricky to maintain relationship between devlink objects and nested devlink instances due to following aspects: 1) Locking. It is necessary to lock the devlink instance that contains the object first, only after that to lock the nested instance. 2) Lifetimes. Objects (e.g devlink port) may be removed before the nested devlink instance. 3) Notifications. If nested instance changes (e.g. gets registered/unregistered) the nested-in object needs to send appropriate notifications. Resolve this by introducing an xarray that holds 1:1 relationships between devlink object and related nested devlink instance. Use that xarray index to get the object/nested devlink instance on the other side. Provide necessary helpers: devlink_rel_nested_in_add/clear() to add and clear the relationship. devlink_rel_nested_in_notify() to call the nested-in object to send notifications during nested instance register/unregister/netns change. devlink_rel_devlink_handle_put() to be used by nested-in object fill function to fill the nested handle.
