Add gesture based lockscreen security. [1/2]
This adds the ability to us a hand drawn gesture as
a means to unlock the device.

In the case that the gesture is forgotton or not
being recognized correctly, the fallback will be the
same as when using patterns.

PS2:
Return SecurityMode.Account as backup for gesture login.

PS3:
Poke the wakelock when a gesture is detected so the screen
will not timeout when an invalid gesture is entered.

PS4:
Clean things up a bit.

HALO colors: a lil improvement

Shouldn't break themeability this time, the custom colors has it's own halo bg
Fix circle not theming
Fix occasionally flickering music control widget.

The problem was seemingly related to the player abandoning audio focus
while the playback state was still set to 'playing'. In that case, the
transport control was removed from the keyguard host because it had no
listener anymore, but later was re-added due to isMusicPlaying() still
returning true. Re-adding it lead to it re-registering with audio
service, which cleared the display due to nothing being connected, which
lead to the detachment listener being called again, which in turned
closed the loop.

While this may be a sign of a buggy player app (it should stop its
playback prior to abandoning audio focus), this situation still should
be handled gracefully. Fix the problem by simply reporting no music
being played while no remote control client is connected.

systemui: Add CONNECTIVITY_INTERNAL permission

 * SystemUI needs to be able to list interfaces if tethering is in use
   and we ask for a second tethering path to be set up (BT+USB, etc).
 * Add permission to stop exceptions in the framework and enable
   tethering thru multiple paths.

Revert "PackageInfo class incorrectly referenced as a struct."

This reverts commit b9b5d8c32e738d3607eec61e5d5bd95ca1521c2e.
Fixes for clang:
PackageInfo is a class, not a struct.
String16 is contained in the android namespace. Do not namespace prefix it
within the android namespace.
Explicitly specify which std classes are necessary to prevent ambiguous
type errors. (map, set)
