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

KeyguardViewMediator: Play lock screen sound sooner

When the screen is locked, there is a long pause before the lock
sound actually plays.

This makes that sound happen much sooner.

Also modified Lock.ogg slightly to remove the initial silence.
