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.

This avoids a NullPointerException when trying to call the callback
and gives a more readable error message.

* changes:
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

Removing the static dependency on guava reduces test compile time
by about 20 seconds on a Z840, thus substantially speeding up the
compile/test cycle.
Make FutureIntent public instead of package-private because it is
used directly by NetworkPolicyManagementServiceTest, which as of
this CL is now in a different package.

This patch extracts into its own independent test a test sub-block looking
for a race condition when not waiting on handlers to become idle:
there is no way to prevent the race from not happening when looking for
it this way. This makes the test flakky.
This new independent test is tagged with @FlakkyTest(tolerance = 3).
Test: ConnectivityServiceTest passes, with higher probability.

This patch defines new Settings symbols for
- setting the probe urls for captive portal detection.
- setting which User-Agent to use for captive portal detection.
The existing default values for these settings are not changed, i.e:
- HTTP and HTTPS probes urls are unchanged.
- the fallback probe is not used.
- User-Agent is empty by default.

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.
