When going over the handler, it could happen with a bad interleaving
we thought that Keyguard was not showing when getting the
onFinishedGoingToSleep message, so we stopped fingerprint
authentication. For some reason our state machine for canceling
/restarting authentication didn't work correctly so the fingerprint
listening state was not correct.

We used to start fingerprint authentication in onFinishedGoingToSleep.
This was a UX issue because then users couldn't place the finger on
the sensor immediately after pressing the power button because
onFinishedGoingToSleep is significantly delayed (around 900ms after
pressing the power button).

To make unlocking work if keyguard is in occluded state and user

If you tap the enter key twice on the keyguard PIN entry
screen, the second tap can sometimes register because keyguard
hasn't been dismissed yet. The fix is to ignore a second attempt
after the PIN has already been verified.

Split off from I0af11da1b7cd7c8d837bc5ba3a62ef2ffca74b1b.
The initial value did not matter previously because
a SystemUI crash triggered the boot logic and forced
a manual entry before fingerprint works.
Long term the timeout logic should be moved to StrongAuthTracker
so it can be shared with the trust agent implementation (currently
implemented by the trust agents themeselfes)

When calling cancel() on the cancellation signal, it doesn't happen
immediately. Now, because of a state messup during boot, we go
through the sequence
startListeningForFingerprint
stopListeningForFingerprint
startListeningForFingerprint
However, the cancellation callback from stopListeningForFingeprint
happened AFTER the second startListeningForFingerprint, so we assumed
that fingerprint detection was not running anymore but in reality it
was - leading to weird states and all kinds of small state messups.
Introduce a state machine to track when we we called cancel but
waiting for the confirmation of FingerprintService in order to track
this properly.

After gettin a callback onAuthenticationSucceded we set the
fingerprint listening state to false. However, when waking up, we
immediately started listening again because the state was false.
Protect against that by only calling authenticate only once, except
when the unlock doesn't go through because unlocking with fingerprint
is not allowed.
Also fixes some animation "jank" because of the state messup.

- Move all fingerprint related to logic in on central class in
SystemUI that knows all the state of the UI so there is exactly ONE
place in which we decide what to do when we acquire a fingerprint.
- When pulsing and we get a valid finger, we fade the contents of the
Keyguard out and fade the scrim out almost the same way as we would do
in a normal wake-and-unlock sequence.
- Hide shadows while dozing, so we don't see the artifacts when we fade
the dozed Keyguard out.

When pulse was about to turn on and at the same time we were starting
a wake-and-unlock sequence, there was jank because the scrim handling
was not correct anymore. Now, abort the pulse when we are wake-and-
unlocking so we don't see flickering with the scrims anymore.

When the device is lost or stolen, it's safer to
fall back to strong authentication (pin, pattern or
password). This disables fingerprint like we do with
trust agents.

This fixes a bug where we were counting short PIN, patterns and
passwords as attempts. For devices with a device policy admin,
this would cause devices to get wiped after a short amount of
interaction with the UI.

- Add callback to inform SysUI when the screen has been unblocked
and turned on.
- Cleanup inconsistent messaging about device interactive/screen on
and off.
- Add callbacks to inform SysUI about screen states
- Implement a quick fade for the scrim after touch, wake, and unlock.
First, start with a black scrim on top of everything, and then fade
it out.
- Make sure we play the normal unlock animation when device is pulsing
- Override navigation bar animations for touch, wake and unlock: Fade
in the same manner as the scrim.
