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

Bug: 10361358
Change-Id: I846ab7a6f84cd49e876ad21e9366aff1600e0530
On modern versions of Android running in AOT mode
FloatMath is slower than Math. Calls to Math.sqrt(),
etc. are replaced by intrinsics which can be as small
as a single CPU opcode.
When running in interpreted mode the new
implementation is unfortunately slower, but I'm
judging this acceptable and likely to be improved
over time. This change saves a small amount of native
code.
Example timings:
Mako AOSP AOT:
Method: Original / New / Direct call to Math
ceil: 596ns / 146.ns / 111ns
sqrt: 694ns / 56ns / 25ns
Mako AOSP interpreted:
Method: Original / New / Direct call to Math
ceil: 1900ns / 2307ns / 1485ns
sqrt: 1998ns / 2603ns / 1788ns
Other calls Mako AOT:
Method: Original / New
cos: 635ns / 270ns
exp: 566ns / 324ns
floor: 604ns / 150ns
hypot: 631ns / 232ns
pow: 936ns / 643ns
sin: 641ns / 299ns
The advice to use Math directly, in preference to
FloatMath, is still good. FloatMath will be deprecated
separately.

Updating the accessibility layer behavior to reflect the new
model where accessibility no longer overrides strong encryption.
Now enabling an accessibility service lowers the encryption
level but the user can bump it up in settings if desired.

To clarify that BluetoothLeAdvertiser object will return null
when BT is off OR if the hw doesn't support these capabilities

Some of the admin policies are throwing security exceptions in
a managed profile without being documented correctly and others
shouldn't be throwing security exceptions.
Changed setCameraDisabled() to not throw an exception. It now just
prevents work profile apps from using the camera.
Changed wipeData() to allow passing in ERASE_EXTERNAL_STORAGE. In
secondary users/profiles, this is just going to remove the user, so
the flag is harmless.
Updated documentation for setKeyguardDisabledFeatures() and resetPassword()
to indicate that they cannot be called in a managed profile.

When restoring hundreds of apps on low-DPI devices, we end up sending
icon Bitmaps inline in the response instead of splitting into ashmem
regions. To avoid triggering TransactionTooLargeException, switch to
using ParceledListSlice under the hood.
