Merge pull request #140 from legendlee1314/new_master

[SystemInfo][Network] Add WIFI network-type and uniform to use C-API listener
[Bluetooth] Remove unused variables
[Power] Fix Power API failures on tct test suites.

-Remove workaround of glib callback as it is not needed anymore : the
extensions run in a separate process.
-Remove commented code in the examples as now switching on and off doesn't
background crosswalk behind the launcher.
[Power] Make test PowerManager_setScreenBrightness_brightness_TypeMismatch pass.

We need to throw the right error when the brightness passed is -Infinite,
+Infinite or NaN.
