Merge commit '463aacfbd220c9ef2f6ed915d54092289fdac05b'
* commit '463aacfbd220c9ef2f6ed915d54092289fdac05b':
wifi: WifiManager.startScan() will now do passive scans by default.
Active scans will only happen if a hidden AP is in use, or if the new method
WifiManager.startScanActive() is called.
This fixes some audio playback problems with bluetooth A2DP.
