LockScreen: allow long-press actions from hardware keys (1/2)

Allow following actions with button long-presses on lockscreen:
- toggle flashlight (if available)
- play/pause/next/previous track selection
- toggle silent mode

Allow customizing of back, menu, and home buttons. Search
button events are completely ignored on the lockscreen.

Auto-detect hardware keys, only show appropriate menu
options based on the actual hardware keys available on the
device (or completely hide if there are no hardware keys).

Based largely on Danny Baumann's work from gingerbread.

Ported from CM10

Use sticky broadcast to convey torch state (1/2).
It doesn't really make sense to store the (non-persistent) state of the
torch in a (persistent) setting. As the torch is sending a broadcast
anyway, make that broadcast sticky and use it to convey the state.

Also unify the torch constants (actions, extras, activity names) at a
common place.

Camera button support: useful features & bugfixes (1/2)
Screw the remapping, let's make something more useful!
Replaced the code to actually launch Camera app, not just fire the shutter.
I won't remove it: it's cool to have an option to double-click Home for Camera.
Added:
  * Camera wake (with button half-press) and unlock options
  * "Peek": releasing the half-pressed Camera button will
    turn the screen back off
  * Camera playback control
