Add support for ICU data pinning in the Zygote
Change-Id: I53a2d5f885df5cf633a4a63cb2e3c2bc5c75959e
Upstream ICU caches use SoftReferences. On Android this means
that useful cached data initialized in the Zygote are "lost" when
the Zygote GCs and cannot be shared with apps. This change makes use
of an Android patch to ICU to ensure References created during
Zygote initialization are "strong". i.e. they are never collected.
This prevents them being GCd and ensures they can be shared between
applications.
After switching ICU to use strong references, this change
also creates DecimalFormatSymbols objects for common ULocales
(ROOT, US and the user's default, if different). DecimalFormatSymbols
makes use of an ICU Reference cache and this alone has been shown to
improve the construction time of java.text.DecimalFormat by 1-1.5
milliseconds on a Seed device. This saving applies the first time one
is created in each app for each locale, and again if SoftReferences
have been cleared.
The cost to the heap size of the Zygote has been measured at ~107k.
This value will change as more caches are switched to use the new
CacheValue class.
Formatting is typically performed on the UI thread and the intention
of this change is to reduce app start up time and jank in apps like
the Dialer which do a lot of formatting when scrolling lists. The
change may also enable more virtual memory page-sharing between
apps, though this is not the specific goal.

Adjust Notification APIs per API council
Change-Id: I282bb2b6e4718f7b1afb3eb418a8d37deaa457b0
Since LocaleList needs to depend on android.os.Parcelable, we cannot let
that class belong to "android.util" package, which causes layering
violation.

We can't use the same instance on both the main and the background
thread, as this will lead to problems.

It's raising alarm bells but there isn't much we can do without a lot
of rewriting inside the ActivityManager. The only consequence is stats
that are off by a little bit.

Hiding the APIs for now since we're not releasing freeform yet and it's
better not to expose them now in case we'll decide to change them later.

There are few paths I can see to get a null intent down into
the framework at this point. Add in some checks and reports
at those places to mitigate and report such problems.
