This patch changes CaptivePortalLoginActivity captive portal test to be
consistent with NetworkMonitor by:
- using Network.java to open the http connection.
- adding a UserAgent property to the request header.
Test: manually tested.

This CL adds:
1) Setter and getter in DPM to manipulate logging switch (retrieval
method to come in a subsequent CL(s)).
2) A way for DPM to register to listen for events.
3) Skeleton of NetworkLogger class (more to come in subsequent CL(s)).

This patch uses the previously introduced TokenBucket to rate limit
ApfProgramEvents, still allowing for burst of ApfProgramEvents when a
new interface is set up (due to ipv4 provisioning, multicast lock, ipv6 RAs
triggering new APF program events in short amounts of time).
Test: new test in IpConnectivityMetricsTest

This patch adds first validation information to:
- ValidationProbeEvent, by extending the probe_type int field of to
also include a bit indicating if the probe was part of a first
validation attempt or not.
- NetworkMonitorEvent, by defining new contants for the event_type
field.

log it and immediately call onProvisioningFailure().
Test: runtest frameworks-wifi
passes, except for selectQualifiedNetworkDoesNotChooseDeletedEphemeral()

Properly account for VPN apps that make heavy use of the tun
interface. Prior to this change a VPN app could be incorrectly charged
for more data than it actually used if it sent more traffic through
the tun interface than the underlying interface.
This change excludes VPN app traffic on the tun interface from the
adjustment pool and doesn't redistribute traffic to the VPN app.
Instead all of the redistributed traffic is deducted from the VPN app
which effectively represents any overhead incurred by the VPN app.

This patch adds an explicit check in the DHCP packet parser for
rejecting packets without a magic cookie, instead of relying on the
top-level try-catch-all in the parser.
This allows to add to DHCP error metrics this specific error.
It also allows to add two poor man's fuzzing tests that tries to find
additional gaps in the DHCP packet parser by
- trying to parse all subslices of a valid offer packet.
- trying to parse random byte arrays.
Test: covered by previously introduced malformed DHCP packet unit tests
+ additional fuzzing tests.

This patch adds a try catch all to DHCP packet parsing so that
DhcpClient does not choke on malformed packets, brinding down with it
the whole framework.

This patch adds the possitibility to send a 3rd fallback validation
probe in sendParallelHttpProbes when neither the 1st http probe nor the
https probe came back with a conclusive answer.
This 3rd probe is only used for trying again captive portal detection
and does not return success, so that network validation always fails if
the https probe fails.
In addition, the url reveals a captive portal is now sent to the
CaptivePortalLoginActivity so that all three probes can use different
urls.

When a network goes into the background, tell netd to set the
network's permission to NETWORK. Also, close all TCP sockets on
that network, to prevent long-lived TCP connections from staying
on it and possibly continuing to use metered data.

This patch connects existing IpConnectivityLog to the new
IpConnectivityMetrics service:
- IpConnectivityLog is now an independent class that pushes events
directly to the new IpConnectivityMetrics service.
- DnsEventListenerService is moved from MetricsLoggerService to
IpConnectivityMetrics.
- this patch also features end to end tests from IpConnectivityLog to
IpConnectivityMetrics dumpsys output.

This patch defines a new metrics service for IpConnectivity events
defined in android.net.metrics, separate from currently existing
MetricsLoggerService.
Similarly to MetricsLoggerService, the new service has an event buffer.
It also implements a dumpsys interface that can be used to flush events
and output a serialized proto.

This contains the following changes:
1. Make NETWORK_AVOID_BAD_WIFI a tristate: 0 means never avoid
bad wifi, unset means prompt the user, 1 means always avoid.
2. Look at NETWORK_AVOID_BAD_WIFI only if the carrier restricts
avoiding bad wifi (previously, we relied on the setting being
null and defaulting to the value of the config variable).
3. Add an avoidUnvalidated bit to NetworkAgentInfo to track
whether the user has requested switching away from this
unvalidated network even though avoiding bad wifi is generally
disabled. This is set to true when the user selects "switch"
in the dialog without setting the "Don't ask again" checkbox.
4. Add a hidden setAvoidUnvalidated API to ConnectivityManager to
set the avoidUnvalidated bit.
5. Additional unit test coverage.

Like a normal (foreground) request, a background request is only
satisfied by one network and will keep that network up. Unlike a
foreground request, when a network only has background requests,
it will linger, and after lingering is complete, it will become
a background network.
Future CLs will cause the system to treat background networks
differently, e.g., by requiring different permissions.

The IpConnectivityLog class looks up MetricsLoggerService once only
at creation. If a IpConnectivityLog user instantiates this class too
early during the boot process, the MetricsLoggerService is not found
and no event can be recorded.
This patch makes IpConnectivityLog attempt to look up
MetricsLoggerService as long as it hasn't found it yet.
This allows IpManager and ConnectivityService to upload
android.net.metrics events.

This patch adds in IpReachabilityMonitor a timestamp variable set
everytime that probeAll() send NUD probe requests to RTNETLINK.
This allows to distinguish between:
1) NUD_FAILED events resulting from such a forced NUD probe
2) "organic" NUD_FAILED notifications from the kernel
This distinction is added to IpReachabilityEvent as a one-bit flag.
This patch also changes the formatting of ApfProgramEvent flags to use
'|' as a joining character, similarly to other flags formatting.

This patch partially undoes ag/869831 (Change-Id:
Ia42ed7aefaebd8caf3eada8e42b6cb7a940d7647) so that ConnectivityManager
does not remove callbacks from its internal request-to-callback map at
unregistration, but instead let the singleton CallbackHandler do it when
receiving a CALLBACK_RELEASED from ConnectivityService.
ag/869831 was thought to fix b/26749700 that reported a callback leak
from sNetworkCallback, but a finer analysis of the code shows that
callbacks were correctly removed by the CallbackHandler before
ag/869831. There was therefore no callback leak.

This patch adds lifetime durations of DhcpClient states to
DhcpClientEvents.
To record the duration of a state, the event is now recorded when the
DhcpClient state machine exits that state.
In addition this patch removes event logging of StoppedState,
DhcpState and DhcpHaveLeaseState.

This patch
- adds a Builder class for RaEvent.
- uses this Builder class for correctly recording the minimum

recording the last lifetime seen.
- adds unit test coverage for RaEvent logging.
