When a client of the NsdService exits, NsdService should
clean up the requests it has sent to the mDNS daemon:
cancel any pending resource-discovery and resource-resolution
queries, and remove any services registered by this client.
If this isn't done, several bad things happen. The daemon will
continue to run unnecessarily, will report service discoveries
that can't be forwarded on to the client, and will continue to
advertise service ports for an application which is no longer
running until the device is rebooted (mDNS pollution).

Due to race conditions or programming errors, the NsdManager
can attempt to process an asynchronous status message (and issue
a callback to the listener) after the listener has already been
removed from the NsdManager state. This causes dereferencing of
null objects, and a crash.
Split out the three async-queue message cases: these are ones
in which message.arg2 does not hold an NsdManager array index
and the code should not interpret this field as if it were.
Add an explicit check for "null listener" (the array index in the
message has already been released), log a warning, and exit early.
Safeguard accesses to the "NSD service type" string from a (possibly
null) NsdServiceInfo object... return a constant "?" string rather
than crashing.

Also add new API for determining whether the current data network
is active, and thus better scheduling network operations. This
API is designed to not be tied to a mobile network -- regardless
of the network, apps can use it to determine whether they should
initiate activity or wait. On non-mobile networks, it simply always
reports as the network being active.
This changed involved reworking how the idle timers are done so
that we only register an idle timer with the current default
network. This way, we can know whether we currently expect to
get callbacks about the network being active, or should just always
report that it is active. (Ultimately we need to be getting this
radio active data from the radio itself.)

We now compute radio active time per application, by distributing
the active time across all applications each time the radio goes
down, weighting it by the number of packets transferred.
Per-app radio power use is now computed using this radio active
time.
This also gives us a new metric "ms per packet", which give an
idea of how effectively an application is using the radio. This
is collected and reported as a new set of stats in the human-
readable checkin. (It can be computed from the raw checkin data).
Also improve sync reporting to include the sync source as used
in wake locks, not just the component name.

This optimizes the path for battery stats to collect
per-uid network usage. It now collects wifi and mobile
usage separately, with a path that allows it to recycle
all data structures and filter out stats it isn't
interested in before they come back to java.
This is setting us up for the actual goal, to collect
mobile stats independently each time the mobile radio
goes down, allowing us to distribute mobile radio usage
across uids based on the number of packets they transferred
during a session.

Refactored the directory structure so that services can be optionally
excluded. This is step 1. Will be followed by another change that makes
it possible to remove services from the build.

Both requests are made using same id; and there is a chance that
stopResolve() is not fully completed when getAddrInfo() is issued. That
results getAddrInfo() failure, because both are using same requestId.
This change fixes this problem by creating a new unique id to call
getAddrInfo() with.

Some services do periodic network time lookups and can wedge the other operations on
BackgroundThread and IO Thread, causing Watchdog to kill the runtime. So best to put
those handlers on separate threads.
Going forward, should convert NTP lookups to be async with callbacks.

netd now tracks statistics for tethered interfaces across tethering
sessions, so switch to asking for all tethering stats. (Currently
we're double-counting all tethering data, ever since it started
tracking across sessions.)
Also catch OOME to handle corrupt stats files, which we then dump to
DropBox and then start over.

For now, this only tests network observers. It works by starting
NetworkManagementService with a fake netd socket, feeding it
inputs, and seeing if the appropriate observer methods are
called.

The default Alarm Manager behavior for KLP+ apps will be to aggressively
coalesce alarms, trading exact timeliness of delivery for minimizing the
number of alarm-delivery points, especially wakeup points.
There is new API in AlarmManager, setExact() and setExactRepeating(),
for use by apps that absolutely *must* get their alarms at a specific
point in time.

The NPE happens because NSD Manager doesn't always notify with a 'good'
notification for SERVICE_FOUND. It can get in a situation where a
SERVICE_FOUND is recevied from MDnsDs demon when processing StopDiscovery
on the messaging thread. When that happens, NsdService sends a message
to NsdManager with an invalid index of the listener.
The fix is twofold. First, we fix NsdService to not generate a message if
it doesn't have a good listener index. And second, we also fix NsdManager
to watch for invalid index.
