This is the same notification as the one shown during legacy lockdown
mode, sans the 'reset' button.
The notification is only shown during times when VPN has not yet
established or has failed, for example during boot or after a crash.

This patch changes sligthly the two web probes mechanism for captive
portal detection and network validation so that DNS resolution is always
done for both probes.
In general the target web servers of the two parallel HTTP and HTTPS probes
are now different. This introduces a bias in the latency measurement of
th HTTPS probe since this latency will also include DNS resolution in
general.

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.

This patch introduces an assertEventuallyThat helper function in
ConnectivityServiceTest which given a boolean function retries until the
function returns true or until a maximum retry time is reached.
This function is used to fix flakyness of testAvoidBadWifiSetting where
the Message posted by reevaluate() could reach the Handler's
MessageQueue after waitForIdle takes effect, resulting in the test to
fail.
Instead of fixing the flakyness by introdcing hard sleep times,
assertEventuallyThat is used to reduce the overall test time.
With this change the test has been observed to pass with 100% success
rate over 50000 invocations.
Test: $ runtest frameworks-net

(cherry picked from commit 99c8294ef0)
Change-Id: If41a24989d5f65aeb439f68741f511b5eb53b18d
This patch fixes flakyness of testRequestBenchmark by adjusting time
limit for callback registration from 100ms to 180ms, and time limits for
onAvailable and onLost triggers from 30ms to 40ms.
With these timeouts the test succeeds 100% over 5000 iterations.
When using 150ms for registration timeout, running the test 5000 times
fails 2 times.
When using 30ms for onLost timeout, running the test 5000 times fails
1 times.
In addition, this patch also cleans testRequestBenchmark and uses the
more stable SystemClock.elapsedRealtime() for duration measurements.

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 changes the way that the ConnectivityThread is lazily
instantiated by using the "lazy initialization holder class idiom".
The first code point that tries to obtain a reference to the unique
ConnectivityThread instance will trigger the creation of the Singleton
class, which will guarantee a thread-safe initialization of the static
INSTANCE field inside Singleton according to the language specs.
This is the Item #71 of Effective Java.
The unique static instance of ConnectivityThread is not stored directly
inside ConnectivityThread class but is stored in a static nested class.
This is to avoid triggering the creation of that unique instance when
Zygote does class preloading at phone startup. Otherwise this would lead
to Zygote creating a new OS thread during preloading, which is a fatal
error.

This patch removes the static singleton looper used by
ConnectivityManager and instead uses the common ConnectivityThread.
This allows to removes the static atomic counter used to track
the number of registered NetworkCallback in ConnectivityManager, because
the looper is not turned off anymore when no callbacks are registered.
Also an overloaded version of sendRequestForNetwork is added taking as a
new parameter a Handler. This will allow to overload various callback
and request related API calls with user provided Handlers.

This patch simplifies CallbackHandler in the following way:
- CallbackHandler directly uses the static references to
sNetworkCallback and sCallbackRefCount. This allows to remove
instance fields in CallbackHandler.
- CallbackHandler does not have a reference to ConnectivityManager
anymore
- CallbackHandler.getObject() is now generic in a type-safe way.

and gives a more readable error message.

DO NOT MERGE: IpConnectivityMetrics: rate limit ApfProgramEvents
DO NOT MERGE: TokenBucket for rate-limiting and throttling
DO NOT MERGE: IpConnectivityMetrics reads buffer size in settings
DO NOT MERGE: CaptivePortalLogin: set mixed content policy to compatibility.
DO NOT MERGE: Add IP conn metrics to dumpsys and bug reports
DO NOT MERGE: IpConnectivity metrics: add version number
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
