This patch fixes NetworkStatsAccessTest by taking into account
DEVICESUMMARY which was added in commit
3a8b343ce5220086c4f71e63f5d42f2d28434c4b.
Doing $ git revert 3a8b343ce5220086c4f71e63f5d42f2d28434c4b shows that
the existing assertions of NetworkStatsAccessTest passed before that
commit.
This patch also changes NetworkStatsAccessTest to use up-to-date testing
style and not depend on the deprecated junit.framework.TestCase.

This patch attempts to fix the remaining spurious failures in
ConnectivityServiceTest, which have two causes:
- waitForIdle() does not take into account the NetworkAgents handlers.
- the deadlines in testRequestBenchmark are sometimes exceeded.
To fix the first issue, waitForIdle() is moved to a test level instance
method and also calls waitForIdleHandler on any non null
MockNetworkAgent. This is expected to fix spurious errors for the
following tests:
- testMobildeDataAlwaysOn
- testLingering
- testPacketKeepAlive
- testMMSonWiFi
To fix the second issue, the deadlines for testRequestBenchmark are
extended by 10ms. Also, the failure message is made more actionable by
providing the total time it took for the operation, instead of printing
the number of dispatches that were achieved before the deadline.

Test: tests pass many times in a row (~500).

The testNotificationsShownAndCleared test was not doing anything
because the list of notification to show was always empty.
This patch fixes this issue and actually makes the test loop on
non-empty collections, and also fixes another ordering issue in
assertions themselves, hidden until now by the first issue.

Introduce a SharedLog that can be shared among all Tethering
components. All log entries go to the same log, and each includes
its subsystem name. Additionally, all entries emitted to the
system log shared the same tag, so can easily be watched.
More subsystems can inherit a SharedLog, but to minimize cherry-pick
conflicts we limit ourselves to these changes only.
Test: as follows
- built
- flashed
- booted
- log output observed via dumpsys
- runtest frameworks-net passes

Also, make all tests start with mobile data always on disabled.
This is because some tests only pass when mobile data always on
is disabled. This doesn't cause any problems when running all
the tests in the file, because these tests are always run after
one or more calls to tearDown, which disables mobile data always
on. However, it does cause issues when those tests are run alone.
Test: new test passes 50 times in a row
Test: ConnectivityServiceTest passes

This patch is a cherry pick of the two following commits:
- 38ea810b27 which addresses several
issues in the public api of ConnectivityManager.
- e73017a135 which fixes the documentation
of several methods in ConnectivityManager public api.
Because the first commit change the public api that is referenced in
the documentation fixed by the second commit, it is not possible to one
without the other. In both cases trying to cherry pick only one of them
results in a build error.
The first commit was submitted successfully on an internal branch before
the checks done in the built got stricter.

(cherry picked from commit 38ea810b27)
This patch adds a space character between "synchronized" and
"(mTheLockVariable)" so that all synchronized block have a consistent
syntax. Basic stats shows that "synchronized (" is x10 time more likely
than "synchronized(".
This facilitates finding all locked sections by grepping.
Test: no semantics changes

This patch introduces between ConnectivityManager and
ConnectivityService a mechanism for propagating back to clients
informative errors in the form of error codes and associated custom
runtime exceptions.
Without error code, the service can only throw a limited number of
different exceptions over Binder. Furthermore the throw site stack
traces are always loss. Although for individual instances of a throw,
the error message can be inspected, aggregations of stack traces from
app crashes sanitize error messages and only leaves the stack traces.
This makes debugging dificult for some service calls such as
requestNetwork that can have a variety of failure modes.
In this patch only one failure mode is codified. More can be added later
at a light cost by: 1) defining an error code, 2) defining an
associated exception, 3) mapping the code to the exception. This patch
can serves as a template for doing so.
Test: $ runtest frameworks-net,
#testNetworkRequestMaximum() detects the new exception type.

For 464xlat scenarios on IPv6 networks, the clatd interface setup
introduces double counting of apps ipv4 traffic. NetworkStatsFactory was
accounting for this on the tx path, but not on the rx path. Also it did
not accounted for the 20 bytes added by the IPv6 header.
This patch subtract correctly the rx and tx traffic from the root uid on
the underlying interface, and also adds correctly the 20 bytes cost per
packet on the stacked interface for 464xlat traffic.
Test: added several new unit tests, based on synthetic data and real
data also.
