driver/wifi: rework CTRL interface manager This commit streamlines the interaction between the Wifi::Manager and the wpa_supplicant's CTRL interface. As user-facing changes it alters some default settings and introduces new features: * Every configured network now needs to explicitly have its 'auto_connect' (to be considered an option for joining) attribute set to 'true' whereas this was previously the default value if the attribute was not set at all. * The 'log_level' attribute is added and configures the supplicant's verbosity. Valid values correspond to levels used by the supplicant and are as follows 'excessive', 'msgdump', 'debug', 'info', 'warning' and 'error'. The default value is 'error' and configures the least amount of verbosity. * The 'bgscan' attribute may be used to configure the way the supplicant performs background-scanning to steer or rather optimize roaming decision within the same network. The default value is set to 'simple:30:-70:600'. It can be disabled by specifying an empty value, e.g. 'bgscan=""'. * The 'verbose_state' attribute was removed alltogether and similar functionality is now coverted by 'verbose' attribute. Implementation-wise the internals changed significantly and are outlined in the following paragraphs. Formerly the interaction between the manager and the supplicant was handled in an apparent way where the internal state of each interaction was in plain sight. This made the flow cumbersome to follow and therefor each interaction is now confined to its own 'Action' object that encapsulates the ping-pong of commands and responses between the manager and the supplicant. All actions are processed in an sequential way and thus there is no longer any need to defer pending actions depending on the interal state of the current interaction. Configuration changes as well as events issued by the supplicant where new actions can be created are handled in this fashion. Of note are both signal-handlers, '_handle_cmds' and '_handle_events' respectively. The state report, which provides the information about the current state of connectivity to a given wireless network, was dealt with in the same vein and its handling was spread across the manager implementation. Again, to make it easier to follow, the generation of the state report is now purely driven by the 'Join_state' object. This object encapsulates the state of connectivity and is normally updated by events issued from the supplicant (see '_handle_events'). It is also incorporated when handling command responses (see '_handle_cmds'). Handling of timed-actions, like scan and signal quality update requests, was done by setting a timeout at the Timer session directly and thus only one timed-action could be pending at any time. This excluded dealing with timed-actions like connected-scanning and signal quality polling concurrently. This was changed and now a One_shot_timeout is used to programm each concurrent timed-action. For implementing the communication channel for the CTRL interface the manager and supplicant use a shared memory buffer, the Msg_buffer. Since the CTRL interface for Genode was implemented using C, some shenanigans were performed to access the memory buffer. Now the CTRL interface implementation uses C++ and only exports the functions required by the supplicant as C. This simplifies the usage of the Msg_buffer and allows for removing the global functions needed for synchronizing the Msg_buffer access as those are now part of the object itself via the 'Notify_interface'. Fixes #5341.
