Display signal strength in dBm with visual indicator in the form of a bar for scan results displayed by wpa_gui-qt4. Any signal > -35dBm is treated as full signal bar, signals between range of -95<->-35dBm are displayed linearly. Convert WEXT signal level value to scale that nl80211 typically reports in dBm. The condition which differentiates 8-bit WEXT dBm and regular dBm is probably fragile, but there is currently no way to know what the driver is going to report for signal strength.
