Wifi: Get the list of supported channels

Get the list of supported channels/frequencies from wpa_supplicant and provide
them thru WifiManager.getSupportedChannels();

One channel is represented thru the class WifiChannel which includes channel
number, frequency in MHz and a flag if IBSS mode is allowed on this channel.

Like isIbssSupported() we can only expect a result after WIFI_STATE_ENABLED has
been reached.

wifi: Fix StringIndexOutOfBoundsException for incorrectly encoded SSIDs

If the last character of a SSID is a unescaped backslash then WifiSsid
convertToBytes() will throw a StringIndexOutOfBoundsException and takes the
whole ROM down.

The issue was reported by andreip in the HTC One X XDA thread. His SSID was
set to "/ Andrew \".

Correct executable bit for source files

Many media files and source code files were marked as executable in Git.
Remove those.

Also a shell script and python script were not marked as executable.

SystemUI: fix memory leaks

ContentObservers are being registered without being unregistered,
causing old objects not to be garbage collected. This causes memory
leak if the classes are destroyed and recreated throughout the
device's uptime.

SearchPanelView is recreated every time the screen is turned on.
StatusBarIconView is created every time a notification is triggered.

FW: Fix AwesomeAction constants

Fixes 3 'Blank' entries in NavBar/Custom Toggle actions.

string & drawable returns.

Fix Photosphere/Camera FCs

Photosphere is setting a few parameters "blindly"
while the API says it should check the device capabilities first.
On TF101 the camera HAL doesn't handle FLASH_MODE & SCENE_MODE
and so it sends the required RuntimeException for these which makes PS to FC

=> check device capabilities & ignore these 2 parameters if the device doesn't support them.
