This patch adds overloaded version of registerDefaultNetworkCallback
registerNetworkCallback, and requestNetwork with an additional Handler
argument that is used for running the caller provided NetworkCallback.
It also clarifies the documentation of the existing methods that
implicitly uses the internal singleton ConnectivityThread about which
internal Handler is used for running NetworkCallbacks.

The request network with timeout was originally created with a
check of max timeout against a constant of 100 minutes. However,
the API was not public and did not implement a timeout. Any users
were internal and never got any onUnavailable() callback (since
timeout never triggered).
There is no reason to have a max timeout so the constant is
remove.

Test: unit tests and CTS of ConnectivityManager
Change-Id: Icbedfb4299d75b6a7e3e43720111531f1faafd06
ConnectivityManager static sCallbackHandler is referenced and directly
used in a way that is not ensuring its proper initialization.
This patch fixes this potential NPE by using getHandler() instead.
Also this patch changes sendRequestForNetwork's signature to only accept
the subtype CallbackHandler instead of Handler: without using
CallbackHandler the NetworkCallbacks are not triggered properly and
bookkeeping of sCallbacks does not happen. sendRequestForNetwork's
signature now makes this explicit.
This step prepares the addition of overloaded versions of
registerNetworkCallback and cie that takes custom Handlers.

This static method returns a NetworkCapabilities instance with
transports and capabilities set according to the given legacy type.
Also:
- add NetworkRequest.Builder.setCapabilities(), to be able to use
the NetworkCapabilities instances returned from the above
- update UpstreamNetworkMonitor to make immediate use of this
Test: as follows
- build (bullhead)
- flashed
- booted
- runtest frameworks-net passes

The current implementation of IdleableHandlerThread is based on
the assumption that MessageQueue#isIdle will return true iff the
message loop has finished processing its messages.
Unfortunately, this is incorrect: isIdle returns true iff are no
more messages waiting in the queue; thus, it will also return
true while it is processing the last message before going idle.
Instead of using idle handlers, take the simpler approach of
posting a runnable to the message loop and waiting for it to
be processed.

Lockdown VPN still needs this to start properly on devices without FBE,

first unlock of keystore may get missed, since USER_UNLOCKED is sent too

This patch removes testNotWaitingForIdleCausesRaceConditions() from
ConnectivityServiceTest because it is in nature flaky and prevents using
ConnectivityServiceTest as a patch presubmit check. Estimated failure
rate is 1/15 on Nexus 6p.
This patch also simplifies how ConnectivityServiceTest waits for
handlers to become idle by removing IdleableHandlerThread and turning it
into a signle static method.

Symptom : Infinite reboot
Reproduce step :
1. Set the Always-on VPN in M OS
2. OS upgrade from M to N
Reproduce frequency : 100%
Reason of issue :
https://android.googlesource.com/platform/frameworks/base/+/9b74791
As you know, in M OS, Always-on VPN information is stored in keystore with encryted.
However, in N OS, there is no encryption when it put in keystore.
So, You deleted keystore check(locked/unlock) logic on ConnectivityService.
By this reason, when device upgrade to N OS(set Always-on VPN), it goes infinite boot.
(Cannot read old always-on vpn information untill device unlock.)
Solution :
I founded exception handling when this case as follows:
If getting Credentials.LOCKDOWN_VPN information has null value(catch the exception),
updateLockdownVpn returns false value.

When network setting reset is started while always-on VPN is enabled,
application crash occurs with IllegalStateException in prepareVpn().
Therefore, it's necessary to also disable always-on VPN in factoryReset
before prepareVpn() when turning off VPN.

- CallbackInfo becomes a static class so that it can be instantiated
and looked at more easily than before.
- CallbackInfo gains hashCode() because it has equals().
- effectively final field are qualified final
- fixes bug when polling the next callback: poll() on a LinkedBlockingQueue
returns null when timing out, which was not failing the test cleanly.

This patch improves system logging around captive portal detection to
make inspection of bug reports sligthly easier:
- NetworkMonitor now logs by default CMD_CAPTIVE_PORTAL_RECHECK and
CMD_CAPTIVE_PORTAL_APP_FINISHED. Other system logs are kept off with
a new VDBG boolean contant,
- NetworkNotificationManager now prints the notification id at
notification time. This allows to easily correlate show and clear.
- errors in NetworkNotificationManager are logged as Throwable instead
of through their implicit toString() method.

During IpManager startup, anything sending messages to the state machine
must not begin doing so until after the state machine has been started.
Reorder the constructor accordingly.
During shutdown, AvoidBadWifiTracker needs to unregister the registered

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.

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.
