Add a simple ArraySet.removeAll(ArraySet) method. This avoids two
allocations, a MapCollections helper and an Iterator object, over
the removeAll(Collection) code.
KeySetManagerService heavily calls removeAll during boot (about 9K
times in AOSP). This reduces GC stress and optimizes the removal
(about half the time the removed collection has only one element).
The removal method in KeySetManagerService is also done under a lock,
so that it gates parallelization efforts in PackageManagerService.

mServer cannot set null, because string from resource always returns
non-null charsequence

- Now aggregate number of times each process has crashed and ANRed.
- Now aggregate total number of connectivity changes.
- Now record connectivity changes in the history.
Crash and ANR counts are new entries at the end of "pr" in checkin.
Connectivity change counts is a new entry at the end of "m" in checkin.
Connectivity changes in the history checkin are Ecn and include the
type of connection and its state.

We have to cache the starting point for the latest "move", then apply it after
we close the path.

Transition PackageManager internals away from heavier HashMap/HashSet
to use drop-in ArrayMap/ArraySet replacements. Saves ~38% RAM and
thousands of objects on a typical device.

Also adds IntArray, which is like LongArray for integers, and prevents
the AM/PM label text in the time picker header from wrapping.

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.

Now "1e-5" will not be separated as "1e" and "-5".
Add one test for this use case.
Make sure we print out the pathData when path parsing has error.

Like "0.0.0" will be separated to "0.0 .0" now, just to make sure we are more
complied with svg path data.
