Currently just valid/invalid based on NetworkMonitor findings.
Changed NetworkMonitor to start out in default state since starting in Offline causes
a spurious invalid report at creation time.
Added some logging.

Previously the Inet state (the little exclamation mark beside the WiFi
and Cellular bars) only transitioned from bad to good once. With this
change it can transition back to bad (and later to good again) if a network
re-evaluation is triggered, say by ConnectivityManager.reportBadNetwork.
Also, avoid triggering re-evaluation in two unwanted cases.

Give unvalidated networks penalized scores and allow them to satisfy
requests.
Previously unvalidated networks were never allowed to satisfy
NetworkRequests and so never caused CONNECTIVITY_ACTION broadcasts.
Previously if there were no other networks present an unvalidated
network would still be made the default. This change formalizes
this behavior using our existing network score logic by assigning
unvalidated networks a highly penalized score.

HttpHandler and HttpsHandler classes have a lot of bug fixes baked into
them that the Network.openConnection() API should be using, for example
disabling SPDY support.

Future HTTP requests could use an old socket that's bound to a different Network
causing unexpected results. DNS results could also not be appropriate.

Network Factories are allowed to go below, but networks need to be
constrained. Allowing the network to go below 0 meant that -1 could
sometimes leak through and foul the logic.
The core of 17361330 will be fixed when we stop sending scores for
listens to NetworkFactories, but it exposed this issue too. Summary:
1 - add a network listener. This isn't a request so it's not sent
to networks.
2 - alter your score (ethernet sets score to -1 when the link goes
down) (16:07:39.782)
3 - a bug in ConnectivityService causes score changes to get sent for
all network requests and network listeners causing NetworkFactories
to no see 2 entities. This bug will be fixed by a pending change
(https://googleplex-android-review.googlesource.com/#/c/540840/).
This causes the ethernet NetworkFactory to see two entities, both
served by networks of score -1. (16:07:39.989)
4 - disconnect Ethernet - this only sends 0 scores for known
requests, not network listeners. Had it been sent for both entities
they both would have evaluated that the networkfactory score (-1)
was lower than the request score (0) and both released their
refcount. (16:08:03.147)
5 - this means the listener is tracked by the EthernetNetworkFactory
with a score of -1 while the factory itself has a score of -1 so the
network release isn't called.

When lingering completes ConnectivityService would log an error message
saying the Network still had NetworkRequests. Fixed by ignoring
listening NetworkRequests which aren't a problem.

Network traffic used to perform the network validation is billed to the UID of
the caller of reportBadNetwork. This change does not change the actions taken
upon validation failing or succeeding: NetworkMonitor will show the sign-in
notification if a captive portal is found. NetworkMonitor will inform
ConnectivityService if a network tests functional. NetworkMonitor will not
take action if a network lacks any connectivity.
Also, remove an unused Thread that was confusing bandwidth billing.

Using reflection you could do this and it would crash the system.

This constructor does nothing, including doing nothing with its
only argument. This causes it to return a NetworkInfo for
TYPE_MOBILE no matter what was passed in.

If we don't do this, per-network HTTP requests will go over the
wrong network if any previous HTTP request was made by the same
app on another network.

This makes tethered clients use the correct DNS servers when
tethering to non-default networks like the DUN APN.

When the NetworkMonitor is told a network disconnected and a sign-in
notification has been shown to the user, the NetworkMonitor requests
the notification be removed. This request goes to the
ConnectivityService who may have already removed the NetworkAgentInfo
from mNetworkForNetId so we cannot look up the NetID in there.
There is no harm in allowing notification hiding for networks that
are disconnected as the notification logic does not effect the
Network state (like the validation message that caused the addition
of the Network liveness check).

correctly stopped adding listen requests to the mNetworkForRequestId
sparse array, but when we remove requests, if it's not getting
serviced by a network, we don't remove it from the network. That
means that when we go to send a notification for that network we have
a request affiliated with the network, but don't have data for the
request and hit this NPE.
If it's not a request, don't do the optimization and remove it only
from the network servicing the request, but instead scan all networks
and remove it from each, if found.
