knownnetworks: Implement KnownNetworks interface knownnetworks.c/.h implements the KnownNetworks interface and loads the known networks from storage on startup. The list of all the networks including information on whether a network is known is managed in network.c to avoid having two separate lists of network_info structures and keeping them in sync. That turns out to be difficult because the network.c list is sorted by connected_time and connected_time changes can be triggered in both network.c or knownnetworks.c. Both can also trigger a network_info to be removed completely.

network: Introduce a concept of known frequencies Each known network (previously connected) will have a set of known frequencies associated with it, e.g. a set of frequencies from all BSSs observed. The list of known frequencies is sorted with the most recently observed frequency in the head.

network: Refactor and move Known Networks management Until now network.c managed the list of network_info structs including for known networks and networks that are seen in at least one device's scan results, with the is_known flag to distinguish known networks. Each time the list was processed though the code was either interested in one subset of networks or the other. Split the list into a Known Networks list and the list of other networks seen in scans. Move all code related to Known Networks to knownnetworks.c, this simplifies network.h. It also gets rid of network_info_get_known which actually returned the list of all network_infos (not just for known networks), which logically should have been private to network.c. Update device.c and scan.c to use functions specific to Known Networks instead of filtering the lists by the is_known flag. This will also allow knownnetworks.c to export DBus objects and/or properties for the Known Networks information because it now knows when Known Networks are added, removed or modified by IWD.

network: Move network offset calculation network_find_rank_index was used to find the offset of the selected network_info among known networks so as to compute a modifier based on the rankmod table. Instead of using known_networks_foreach for this, moove it to knownnetworks.c where it can be coded and optimized separately. For now provide a simple for loop implementation.
