This allows you to make an emergency call without needing to decrypt
your device first.
The exact appearance of the button, and the two possible icons shown to
the left of the text, are taken directly from the corresponding
framework resources (see keyguard_screen_*.xml, ic_emergency.png, and
stat_sys_phone_call.png.)
Also, the code in CryptKeeper.java for updating the state of, and
handling clicks from, the "Emergency call" button is mostly duplicated
from the corresponding code in LockPatternUtils and
LockPatternKeyguardView under frameworks/base.

Move the decrypt attempt to a AsyncTask. This will
unblock the UI thread in order for the device to
still be "responsive". There is still the issue of
decrypt taking 3+ seconds before it returns to. The
delay is still there becfore the fade but the text
field is now cleared and you can tap on keys.

* Use the DPM to determine if we are encrypted.
* Fix misspelling (Comfirm -> Confirm).
* Animate to black when enabling encryption.
* Add holo droid background.
* Change the progress bar to indterminate.
* Display the percentage complete in the status line.
* Fixed bug 3388097. You will no longer have to unplug your device to start encryption. This line is intentionally long. I could make it shorter but I am proving a point: <magic>overflow: auto;</magic>.
* Actually hold onto the wakelock to prvent the device from sleeping.
* Implement onStop() as a orientation change can happen at boot. This will start the activity twice and there will be multiple handlers with messages.

* Grab a full wakelock while encrypting.
* Fix a bug with failed attempts.
* Add a custom theme to animate the screen to black.
* Fix the keyboard to be displayed properly in landscape and portrait.

* Actually post the correct message every 5 second for the progress bar.
* Update the text for the settings to a more finalish version.
* Check the battery status before allowing encryption to proceed.
* Display a place holder message if no password is set for the device.

* There is now a 30 seconds delay after 10 failed password attempts.
