Framework: Fix GSM signal strength

Certain OEM gsm ril libs send back a bogus value for LTE signal
that causes SignalStrength.java to default to LTE and report
incorrect signal values.
Use prop value ro.telephony.ril.v3=signalstrength to get proper
GSM signal reading on certain devices.

Disable touch while using the stylus (Galaxy Note)

Android 4.0 cannot form multitouch events from multiple input
devices. So it is not possible to report one touchpoint from the
stylus position and, at the same time, another touchpoint from a
finger touch. Instead, when a new input device starts up the currently
active input is cancelled. This is highly undesirable while writing
with the pen.

The easiest solution is to ignore non-stylus touch events while the
stylus is within range (hovering) of the touchscreen. For example,
N-trig digitizers implement this in hardware. But wacom digitizers do
report pen data simultaneously with touch data. This patch disables
(non-stylus) touch input within 50ms of stylus data. On my Galaxy
Note this is necessary to make stylus input usable.

input: Add option to toggle pointer icon when using stylus

* The visible pointer icon when hovering or drawing with the stylus is
  quite annoying when trying to actually draw with it. Turn it off by
  default and add an option to turn it on.

Fix HTC headset handling.

HTC's headset driver adds additional bits to the switch state, which
we're unable to deal with. Fix that by masking out those bits and
keeping only the valid ones.

Add config_hasRemovableLid

If a device features a dock with a removable lid, lidOpenRotation
overrides the rotation even if it was undocked (technically the lid is
still open).

This setting tells the framework whether to apply lidOpenRotation to
undocked devices.
