Split the WSC D-Bus interface class (struct wsc) into a base class
common to station mode and P2P mode (struct wsc_dbus) and station-
specific logic like scanning, saving the credentials as a known network
and triggering the station-mode connection (struct wsc_station_dbus).
Make the base class and its utilities public in wsc.h for P2P use.
Create struct wsc_enrollee which is allocated with wsc_enrollee_new,
taking a done callback as a parameter. The callback is always
called so there's no need for a separate destroy callback. The object
only lives until the done callback happens so wsc_enrollee_cancel/destroy
can only be used before this.
Looks like the rest of the file is simplified thanks to this.
Split the interface-specific logic from the core WSC logic. The core
WSC code is the part that we can re-use between P2P and station and
doesn't include the D-Bus code, scanning for the target BSS or the
attempt to make a station mode connection.
- wsc module does not need nl80211 any longer, so remove it.
- Move wsc_init & wsc_exit declarations to iwd.h and remove wsc.h
- re-arrange how wsc_init & wsc_exit is called inside main.c.
