Try sticking with integer-based math as much as possible for speed,
but switch to double-based math if we detect that we'd end up
causing an overflow.
New tests to verify.

When a carrier provides an "anchor" of data usage at a specific
moment in time, augment the network statistics used by warning/limit
thresholds and Settings UI. For example, if the OS measured 500MB
of usage, but the carrier says only 400MB has been used, we "squish"
down the OS measured usage to match that anchor.
Callers using the hidden API will have their data augmented by
default, and the public API offers a way to opt-into augmentation.
Thorough testing to verify behavior.

This patch adds a layer of asynchonicity to the NetworkBaseObserver
callbacks implemented by Nat464Xlat in order to allow these callbacks
to run on the main ConnectivityService handler.
This allows to run interfaceLinkStateChanged and interfaceRemoved
callbacks in the same thread context as other Nat464Xlat methods and
solves the following issues:
- NPE risk due to race between fixupLinkProperties called on the
ConnectivityService thread and interfaceRemoved called as a
callback by NetworkManagementService.
- stale LinkProperties reads in both callbacks not called on
ConnectivityService handler.
- removes the race between stop() and interfaceRemoved().
This patch also:
- removes/simplifies comments related to the threading
model which are no obsolete.
- extract clatd management logic from ConnectivityService into
NetworkAgentInfo

This patch does some cleanup of Nat464Xlat internal state guards
against the Nat464Xlat state Idle | Started | Running, which reduces
code nesting.
It also replaces introspection of internal state for distinguishing
between different stages in 464xlat lifecycle with an enum explicitly
introducing these three Idle | Started | Running states.

This patch does some minor refactoring of clat starting/stopping code:
- remove unused LinkProperties arguments in updateClat
- remove unused Context argument in Nat464Xlat ctor
- introduce ensureClatIsStarted and ensureClatIsStopped methods and
simplify updateClat
- add clatd to NetworkAgentInfo toString() method
- clarify some comments
This changes prepare for moving BaseNetworkObserver callbacks to
ConnectivityService.

1. Mock the service manager so that NMS can fetch mock versions
of INetd and IBatteryStats.
2. Call LocalServices.removeServiceForTest to avoid a duplicate
service registration error. // check this
3. Change the timeout from 100ms to 200ms, as otherwise the tests
that check for IfaceClass fail.
4. Convert NetworkManagementServiceTest to JUnit 4.
5. Move NetworkManagementServiceTest to tests/net
