keyguard: enable magnetic target if no custom targets defined

When no custom target is defined (the "reset" button is pressed
in settings), the unlock target will always be at the right
regardless of the direction the user dragged to.

Remove unnecessary updateSurfaceScreenOn call.

This change stops updateSurfaceScreenOn() from being called one time
right after another. It's called at the end of stayAwake(boolean awake),
which is called right before updateSurfaceScreenOn() in release().
Fix Photosphere/Camera FCs

Photosphere is setting a few parameters "blindly"
while the API says it should check the device capabilities first.

On TF101 (and probably other devices) the camera HAL doesn't handle
FLASH_MODE & SCENE_MODE and so it sends the required RuntimeException
for these, which makes Photosphere FC the Camera app.

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

Fix based on following Team EOS patch: https://review.teameos.org/#/c/1598/

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.

Add UsbDebuggingManager and UsbDebuggingActivity to LegacyUsbManager

The UsbDebuggingManager listens to adbd requests and displays a dialog
when the public key authentification fails, for the user to confirm if it
wants to allow USB debugging from the attached host. If the user chooses
to always allow USB debugging, the UsbDebuggingManager writes the public
key to adbd's config file so that the public key authenfication succeeds
next time.

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.

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 \".

PowerMenu : Improve keyguard filtered actions

Replaces the check for visibility of lockscreen with the state
of the keyguard instead. This avoids the situation where actions
returning false from showDuringKeyguard, are still shown if user enters
emergency call screen.

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.
