30145d755c Remove assertEventuallyTrue as it's unnecessary.
The calls in testAvoidBadWifi are no longer necessary now that
waitForIdle is reliable, and the calls in testPacketKeepalives
are replaced with a wait for the NetworkAgent to disconnect.

Test: ConnectivityServiceTest passes 100 times in a row.

58ebe1c6f1 Rename AvoidBadWifiTracker to MultinetworkPolicyTracker
Rename the class and ensure that all code related to bad wifi
avoidance has names that reflect its purpose.  This will allow us
to reuse most of the the code for other purposes in future CLs.

ae3ce81cc3 Attempt to make waitForIdleHandler reliable.
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.

Test: see other CLs in this patch series

4456f33a95 ApfTest: fix flaky testApfFilterRa.
testApfFilterRa is failing with probabiliy 1/10 ~ 1/15 on the following
assert: assertDrop(program, packet, lifetime/6), for lifetime values
that are multiple of 6, where 6 is the hardcoded fraction of RA lifetime
to filter in ApfFilter.java.

When the lifetime is not a multiple of 6, the remainder of 1 to 5
seconds gives enough margin so that when the APF program is simulated
the faked lifetime of the program is less than lifetime/6 away and the
packet is dropped.

However for lifetimes which are exact multiples of 6, this margin is
always 0s and that result in nondeterminism in the result. This is
consistent with the obervation that the only failed assert was for a
lifetime of 300s, the only multiple of 6.

This can be observed by detecting the age limit at which the filter
stops dropping packet oscillating between lifetime/6 and lifetime/6 + 1
for lifetimes which are multiple of 6.

This patch fixes the flakyness by freezing the flow of time in tests so
that the expected filter age threshold is consistent and stable.

Test: no failure observed in 1000 runs.

ad4db4ed58 ConnectivityServiceTest: remove flaky waitForIdle test.
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.

4e1619f034 ConnectivityServiceTest: some fixes in CallbackInfo
- 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.

53d83d5142 DO NOT MERGE: ConnectivityServiceTest: fix testAvoidBadWifiSettings
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.

cbf8ff83a8 DO NOT MERGE: Fix ConnectivityServiceTest testRequestBenchmark
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.
