Network specifiers are used for 2 purposes:
- As part of network requests to specify more information on the type
of requested networks.
- On network agents to specify information about their networks.
The network specifiers of the requests and agents are matched to each
other. However, the agent network specifier may contain sensitive
information which we do not want forwarded to any app.
This CL adds an option to strip out this agent network specifier before
the network capabilities are forwarded to the app.

Make Nat464Xlat talk to netd directly instead of through
NetworkManagementService. The methods in NetworkmanagementService
don't really provide any value: since the only thing they do is
call into netd, we might as well have the callers talk to netd
directly,
In order to do this, pass INetworkManagementService and INetd to
the NetworkAgentInfo constructor, and update callers appropriately.

The system server is controlling the tcp buffer now by writing to
/sys/kernel/ipv4/tcp_{rmem,wmem}_{min,def,max}. Those files are
basically the same as /proc/sys/net/ipv4/tcp_{rmem,wmem} except those
latter ones contain all three values in one file. Netd can directly write
to those files so we no longer need to depend on these android specific
files.

The current timeout is short enough that lingered networks are torn down
before assertions can be run, causing flakyness in testMultipleLingering.
This CL sets the timeout to 300 in that particular test.
Verified that 300ms is enough with 500 successful runs on Sailfish.
An alternative would be to mock firing of the lingering timer, but
keeping the WakeupMessage logic realistic has already proven useful in
detecting races.

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.
