Also, move over DateFormat.getInstance(SHORT) instead of
LocaleData.shortDateFormat4 (which forces 4 digit years).
Based on an analysis of git history, there seems to be no
real motiviation for using 4 digit years.
If anyone in the platform complains loudly, we could look at
using a skeleton pattern instead of just replacing 'y' with 'yy'.
If third party apps are affected, we could add a targetSdkversion
based check and revert to the old behaviour for older targetSdks.

The 24 hour setting was not respected correctly. Also
fixed a bug where the next alarm would not display itself
in the QS panel.

The "moreChars" test in StaticLayout's generate method would evaluate to
false when the last character in a word caused the break. This in turn
suppressed the ellipsis in this case. The proposed fix is always to set
moreChars true in the code path where the line is broken because more
text wouldn't fit.

libcore now offers a wider variety of 12-/24-hour time formats,
so be more specific about which one we want here.

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.

All supported locales use only U+2025 and U+2026 to represent
ellipses, and it will unlikely change in future. Given translated
resources are inconsistent and often use three dots it is safer
to use constants instead of resources.

With a hardware keyboard, using up arrow within the top line should
move to the beginning of the buffer, to better match desktop text
editing expectations, and similarly for down arrow on the last line.
This patch implements that behavior.
