immersive mode: don't unconfirm a package, that's just dumb

* This is very annoying for specialized apps
* See here for a great explanation http://stackoverflow.com/a/20309721
* The fact that it doesn't even notify the user until the NEXT time they
  run it makes it completely pointless in my opinion anyway.

Merge "immersive mode: don't unconfirm a package, that's just dumb" into cm-11.0
Revert "ActivityTrigger:  New class to invoke when activity starts/resumes"

 * No longer supported upstream, and will be superseded by new
   CM functionality.

This reverts commit c5bb1bbd0a59640ec394ee729b57de34295a4e99.

perf: Improve performance profiles

 * Performance Profiles is going to grow into a much more powerful
   feature which can apply advanced optimizations or power saving
   techniques depending on both the state of the hardware as well
   as the current applications in use.
 * Refactor the original code and move it into PowerManager so
   that it's managed from the same place.
 * Implement "automatic performance profiles". This feature will
   automatically select a profile when specific activities are
   running. Currently this list is static and engages performance
   mode for several benchmarks (trollface).
 * Added support for a new power hint, POWER_HINT_SET_PROFILE.
   Currently, these profiles are fired using a property trigger
   in init. This is easy, but the PowerHAL can do more.
 * Moved the setting to Settings.Secure and also wrapped calls
   to the service in the DEVICE_POWER permission. Nobody should
   mess with this stuff except the system.

TODO:
 * Allow user configuration per-app.
 * Implement an advanced power-saving mode.

PEEK: Beautify bridging layers code

* Save new instances for Peek and PowerManager:
    Create it only in BaseStatusBar when start() method is called. That one
    will be passed throught the sub layers such like new helper class so another
    feature can check Peek state invocking from NotificationHelper class.
* Move phone listener to new helper class.
* Do not show Peek on sim pin lock screen.
* Process new incoming notifications only if screen is off, keep updating notification array separately.
* General cleanup.
