Instead of deriving network identity based on raw subsystem broadcasts,
listen for updates from ConnectivityService. Added atomic view of all
active NetworkState, and build map from "iface" to NetworkIdentity set
for stats tracking.
To avoid exposing internal complexity, INetworkStatsService calls use
general templates. Added TelephonyManager mapping to classify network
types using broad labels like "3G" or "4G", used to drive templates.
Cleaned up Objects and Preconditions.

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.

Teach ConnectivityManager about UID-specific rules derived from policy,
such as rejecting network traffic on "paid" interfaces. Calls that
return NetworkInfo now filter based on any REJECT rules in effect for
the calling UID. (Added uid parameter if callers that still want all
interfaces.)
Changed NetworkPolicyManager to derive rules based on current policy
combined with PowerManager and ActivityManager status, which it passes
to ConnectivityService for eventual enforcement through netd. When
rules change the usability of a NetworkInfo for a specific UID, it also
dispatches CONNECTIVITY_ACTION broadcasts to that UID. Combined paid
and background policy together to match current working definition.

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.

Add DhcpStateMachine for interation with dhcpcd
- Supports wakeup and renewal on dhcp
- Supports multiple controllers to use the state machine
simultaneously
- Optionally, a controller can request a notification prior
to DHCP request/renewal being sent

Settable per network so you can have not timeout for some and some for others.
If you set the old NETWORK_RESTORE_DELAY_PROP_NAME system property
(android.telephony.apn-restore) it will override this value.

Dependencymet sets the default dep-met value for the network. Should
be set to true unless you know what you're doing.

Don't keep unused global references to classes, don't throw exceptions
when an exception is already pending, and fix a (harmless) misunderstanding
about how GetStringChars works.

This reverts commit bbba216fe3
and is the first of the LTE commits in master being back ported
to the LTE branch.

Adding them hidden so that if OEM's are rolling their own at least they can
use the same values. Will mark them unhidden in a future sdk release.

It doesn't work (yet) for IPv6, but we can remove v4-centric notions from the framework.
