Currently, when a network goes into CONNECTED state, we call
updateLinkProperties and then notifyIfacesChangedForNetworkStats.
The latter is unnecessary, as there are exactly two cases:
1. networkAgent.linkProperties != null: updateLinkProperties will
call notifyIfacesChangedForNetworkStats, because oldLp is null
and networkAgent.linkProperties is not null.
2. networkAgent.linkProperties is null: there is no need to call
notifyIfacesChangedForNetworkStats, because no interfaces were
added or removed. When they are, updateLinkProperties will be
called again.
Removing the call to notifyIfacesChangedForNetworkStats avoids
a stats poll, which is a minor performance improvement.
Also, remove the NetworkStatsService code to do asynchronous
interface updates, since it has no callers.

This has no concrete impact on the behavior of ConnectivityService,
but in principle TRACK_DEFAULT requests should not be counted toward
requests that make a network foreground. It does not have an impact
because only VPNs could be affected by this, and VPNs are always in
the foreground by definition.

NOT_SUSPENDED and FOREGROUND are capabilities that need to
be public so as to reach feature parity with what information
can be gotten through the use of CONNECTIVITY_ACTION and
synchronous calls to ConnectivityManager. This change makes
them public, and wires up the NOT_SUSPENDED capability.
This deprecates in effect the old onSuspended and onResumed
callbacks, but these have never been public.
This also converts the onAvailable path from a multiple
binder call design to a simpler, single binder call. This
is only for internal convenience

Prior to this change ConnectivityManager used to patch in the UID
of the requesting app inside the NetworkCapabilities sent to it.
The rationale was that the app may not know what other apps may
use the network, so the view it should have of the network should
always say the network only applies to that app.
But this has an unfortunate side effect : apps can't match the
received network against a default NetworkCapabilities. Ostensibly
this only applies to the system because all involved calls are
@hide, but still : system code would get some NetworkCapabilities,
for example using networkCapabilitiesForType, and then try to
match the capabilities of an available network using
satisfiedByNetworkCapabilities. Because the passed network is
declared to only apply to one's own UID and the UIDs of the
NetworkCapabilities are set to null meaning "I need this network
to apply to all UIDs", the answer will be "false".
While this is WAI in a sense, it is very counter-intuitive that
code trying to match a network would be required to patch in its
own UIDs.
There are three ways of fixing this :
1. Require all apps to do the above. It's correct, but it's
cumbersome and counterintuitive. Multiple places in existing
code needs to be fixed, Tethering is an example.
2. Write the UIDs of the caller in any NetworkCapabilities object
that is created. This is not very practical, because it imposes
the converse requirement on all NetworkAgents, which would then
have to clear the UIDs before they send the capabilities to
ConnectivityService. All NetworkAgents need to be fixed.
3. Instead of sending an object with a list of one UID to apps,
send a null list. The drawback is that the networks nominally
look to apps like they apply to all apps. I argue this does
not matter ; what matters is that the UID lists do not leak.
Clients just see a null list of UIDs (and third party can't
even access them without using reflection). No other changes
are required besides this two-line patch.
This patch implements 3. I believe it is the saner approach, with
both the most intuitive behavior and the best backward compatibility
characteristics, as well as the easiest change.
This does not encroach on the future plans to make the actual
UID list available to apps with NETWORK_SETTINGS.

This change prevents IpSecTransforms from being inadvertently modified
by changes to the IpSecConfig. Specifically, once the transform is
created, it takes a copy of the config, rather than a reference.
