On many devices the radio version system property is only available
when the radio is on, which is frequently not the case when the static
initializers for the Build class are run (eg, if the system has just
booted). This means RADIO is forever "unknown" on these devices.
Deprecate it and add a method to return the radio version instead.
Apps will still have to deal with getting a null back if the radio
version is currently unavailable.

This change attempts to avoid a periodic and costly 110ms
explicit GC and instance count operation when StrictMode
activity leak checking is enabled.

Clear the Message when it is recycled, even if it will not go
back into the Message pool. This makes the behavior of recycle()
more consistent and ensures that the Message does not hold onto
other object after it has been recycled (useful in case there are
stale references to the Message lingering elsewhere).

Also fix issue #4519821:
Blank screen displayed on tapping "Battery Use" option in the settings
We weren't correctly doing the full Activity resume code when coming
back from delivering a new Intent or result.
And fix a fragment problem where we still weren't correctly restoring
the state of list views. (I think this was from a bad manual-merge
from master.)

Periodically records delta network traffic into historical buckets to
support other services, such NetworkPolicyManager and Settings UI.
Introduces NetworkStatsHistory structure which contains sparse, uniform
buckets of data usage defined by timestamps. Service periodically
polls NetworkStats and records changes into buckets. It only persists
to disk when substantial changes have occured. Current parameters
create 4 buckets each day, and persist for 90 days, resulting in about
8kB of data per network.
Only records stats for "well known" network interfaces that have been
claimed by Telephony or Wi-Fi subsystems. Historical stats are also
keyed off identity (such as IMSI) to support SIM swapping.

/mnt/sdcard is the real mount point. /sdcard is just a symlink.

Added startDataProfiling() and stopDataProfiling() to TrafficStats,
which can be used by apps to measure network usage delta between two
points in time. Currently takes two NetworkStats snapshots and returns
delta, which will eventually include tag-level granularity. Added
tests for NetworkStats delta subtraction.
Added NMS.getNetworkStatsUidDetail() that returns stats for specific
UID. Always gives stats access for the calling UID, otherwise enforces
that caller has permission. Fix readSingleLongFromFile(), since
/proc/ files don't have well-defined lengths.
