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.

GCC 4.4 cleaned up some more C++ headers. You always have to #include
headers directly and cannot rely for things to be included indirectly.
