Remove the navigation camera icon in keyguard if disabled by DPM

The logic here is incorrect: the camera shortcut is/should be accessible
even with a secure lock screen. As a result, a device with the lock
screen camera disabled by DPM and an insecure lock screen would still
display the unfunctional shortcut.

Limit QC camera features to post-ICS HALs

for histograms

WifiController: fix high perf lock sometimes not respected

When the device screen is turned off, the state is DeviceActive for
15 minutes. In this time, high perf lock is not respected and
Wi-Fi power-saving mode will be turned on because screen is off.

Fix by adding a new DeviceActiveHighPerfState.

AppOps: track op persistence by name instead of id

On XML write, include the op name.  On XML read, map
the name back to op id (if it exists).

Persistent AppOp state now follows the op name instead
numeric id.  This allows upgrades between versions of
android that have different code<>name mappings.
