If we need carrier entitlement checks don't show the hotspot tile
which could bypass them, instead make the user go to settings.

Query for the current proximity value before starting a pulse.
If a "near" value is returned, skip the entire pulse.

When creating a user via the UI, disallow phone calls and SMS by
default. Primary user must explicitly enable it via Settings.

+ Now when a Bluetooth device disconnects, and the user is looking at quick
settings, the Bluetooth icon and text will update with the new state of
diconnected.

When we were fading out the preview for phone/camera to crossfade to
the real application, it might have been that showKeyguard was
called in the middle of this transition. This change makes sure that
we cancel this animation when showing the keyguard.

* commit 'd092fc7076310fca5edd089df5bb5398096f6627':
Ensure that we don't show excluded tasks when we are not in that task (Bug 17657618) - Fix regression with launching an affiliated task due to clipping changes (Bug 17755902) - Tweaking previous changes to home transition - Disable the debug mode option
Avoid waking up the device on hw vol key presses during a doze
pulse. Instead, behave as if the screen was off for these keys,
namely forwarding them over to the session manager.

- Fix regression with launching an affiliated task due to clipping changes (Bug 17755902)
- Tweaking previous changes to home transition
- Disable the debug mode option
The motivation is an API change: FloatMath is going to be
deprecated and/or removed. Performance is not the goal of
this change.
That said...
Math is faster than FloatMath with AOT compilation.
While making the change, occurances of:
{Float}Math.sqrt(x * x + y * y) and
{Float}Math.sqrt({Float}Math.pow(x, 2) + {Float}Math.pow(y, 2))
have been replaced with:
{(float)} Math.hypot(x, y)
Right now there is no runtime intrinsic for hypot so is not faster
in all cases for AOT compilation:
Math.sqrt(x * x + y * y) is faster than Math.hypot(x, y) with
AOT, but all other combinations of FloatMath, use of pow() etc.
are slower than hypot().
hypot() has the advantage of being self documenting and
could be optimized in future. None of the behavior differences
around NaN and rounding appear to be important for the cases
looked at: they all assume results and arguments are in range
and usually the results are cast to float.
