quiethours: fix vibration logic

While QuietHours have different modes for haptic feedback and vibration, indeed
both uses the underlying VibratorService. This change adds some basic logic to
detect what quiethours mode should be applied to block access to vibrate calls
during quiethours.

This patch assumes:

1.- Single pattern vibrate calls are treated as haptic feedback if milliseconds
vibration is lower than 70 milliseconds
2.- Multiple pattern vibrate calls are treated as haptic feedback if the total
duration of the pattern is lower than 70 milliseconds and they doesn't need to
be repeated.

NetworkController: Extra WIMAX icon handling

- Fixes the dependency on 3g (or other mobile data)

  removing the wimax icon if wimax is connected.
- Continue to show the network carrier type if
  phone is out of service but wimax is still connected.

AudioService: Reduce volume to safe level when headset is connected (2/2)

This is a safety feature for users who opt to raise volume above the designated
safe level while using a headset.

Currently when a user does this they are provided with no protection against
dangerously high volume levels until the next time the headset volume warning
is displayed.

This patch adds an optional feature to ensure volume is no higher than the safe
level every time a headset is connected.
