Re-implement orientation aware volume buttons at lower level

Rework of http://review.cyanogenmod.org/31979

Fixes:
1. inconsistent volume button behaviour depending on app in use
   - the buttons not swapped for some NDK/OPENSL ES apps like
   e.g. MX Player
2. the function of volume buttons on external input devices like BT/USB
   keyboards should not be affected by the main unit orientation

This commit finishes http://review.cyanogenmod.org/18273 - use of system
property has been replaced with config push via JNI as suggested during
the original review.

Patch Set 2: Circumvent the need for "keyboard.orientationAware = 1" idc
Patch Set 3: Don't leak implementation details outside InputReader

PieService: fix possible race condition.

onPieActivation declared as a oneway function (call to it will not
block code execution). If client calls back to gainTouchFocus or
restoreListenerState very quickly then race condtiion happens
and mActive might be false in gainTouchFocus/restoreListenerState.

Set mActive before calling onPieActivation to avoid race condition and
drop the flag if exception happens.

PackageManager: Limit the platform-key protection to test-keys builds

This block (change I7390b3bdf5289411f7a335c69635bed9f74bbfb3) is intended
to protect the system from abuse of well-known keys. That's not the case
if the system is signed with dev or release keys.
