DevicePolicy: Fix lockNow() failing to turn off screen

Pawit Pornkitprasan's patch from ICS.  This issue affects JB as it did ICS.
Original patch: http://review.cyanogenmod.com/#/c/14845/

---
A fix introduced in 93c518e4f8abd98f87cda1712b30a5a86cfa60dd
causes lockNow() to sometimes (most of the time) fail to turn
off the screen. The screen will turn off, but then immediately turn
on showing the lock screen.

This is caused by getWindowManager().lockNow() call which calls the
method to lock the screen, which the PowerManager service also
call in parallel, leading to a race condition.

The fix is to only call getWindowManager().lockNow() if the screen
is not on.
Add SET_ALARM permission for SystemUI

If one or more third-party alarm clock app is installed, clicking clock should open an app chooser for the alarm clock. However, permission for com.android.alarm.permission.SET_ALARM is required to make this behaviour work properly.

See http://forum.xda-developers.com/showpost.php?p=33155463&postcount=2749 for symptom if this permission is not assigned.

EventHub: Modify the keyboard layout file name for headset button

The keyboard layout file name was formed based on the name of
tabla sound card on current machine. If it doesn't find such
file, it is going to use Generic keyboard layout where the
key mappings are different, even though the scan code is same.
The sound card name differs across different machine types.
So, generalising the keyboard layout file name will work across
all machine types.

frameworks/base: Fix for headset switch detect

- Headset Switch detect is not functional
- Headset driver on modem in 8x25 and 7x27A targets
  introduces a delay of 500ms before reporting headset
  events to application processor to avoid the problem
  of spurious interrupts being reported due to hardware
  limitation on these targets. Frameworks code in JB
  treats button release event received after 500ms after
  button press as long press event and generates WEBSEARCH
  event. Due to this all the events in 8x25 and 7x27A
  are interpreted as long press events.
- To avoid this problem increase the timeout to more than
  500ms by introducing headset hook delay property for
  these targets.

frameworks/base: Fix for UI freeze issue with headset insert/removal

- UI freeze is observed while quick insertion and removal of headset
  for multiple times.
- notifyJackSwitchChanged() acquires mHeadsetLock and waits on
  phoneWindowManager lock to call update() as it is a synchronized
  function. sendIntents() is also "synchronized". This function also
  tries to acquire mHeadsetLock. So there is a dead lock, when the
  notifyJackSwitchChanged() acquires the mHeadsetLock before this
  function does.
- update() is called only from notifyJackSwitched() and need not be a
  synchronized function. Removed synchronization on the update() to
  fix the issue.

Expanded desktop capability (2/2)

        Originally authored by Jesús David and ported from
        ParanoidAndroid ICS branch
        https://github.com/ParanoidAndroid/android_frameworks_base/commit/3b6ee6e7ee0a124eec5841763e05eb57c82422e6

        Adds an option to settings to add an expanded desktop option to the power menu.
        By default the option does not show in the power menu.  When used it hides the status bar and
        navigation bar (if there is any).

        With thanks to Paul Beeler for much rework.

        Patch set 1: Initial revision.

        Patch set 2: Replace tabs with spaces in commit message.

        Patch set 3: Add history to commit message.
