power: Add panel auto-brightness configuration

 * Some panel hardware requires that we twiddle some knobs in sysfs to
   enable proper display calibration (gamma, etc) when auto-brightness
   is enabled. Add a configuration value to handle this.

Keep keyboard lit until the screen is dimmed

Do not use button timeout for keyboard (which is intrusive on QWERTY
sliders). Keep it lit until the screen dims instead of turning it off
like the buttons after 5 seconds. Also consider setting keyboard
visibility as a user activity.
input: added support for multiple keyevents

- Multiple keyevents can now be send from the command line:

    input keyevent <key code number or name> ...

  Sometimes invoking 'input' repeatedly does not send the events fast
  enough, this change solves the problem by allowing multiple key code
  number or names be added to the command line.

aapt: allow toggling "errors instead of warnings"

* This patch makes the default behaviour same as AOSP,
  treating untranslatable strings in any but the default
  locale as warnings.
* Setting the environment variable AAPT_ERROR_ON_WARNING to
  anything will make those warnings, errors.
