This patch changes instrumentation of default networks and default
network events:
- stop logging events for default network transitions,
but instead consistently log one event per continuous segment
when one given network was the default, including logging an
event for when there is no default network.
- keep a separate rolling buffer of DefaultNetworkEvent for
dumpsys and bug reports.
These changes allow to simplify post aggregation of default network
event metrics by removing any need to do time series processing.
Instead, metrics and counters can be implemented withouth any ambiguity
by following the recipe:
% of x = sum(duration | x = true) / sum (all durations)
where x can be various conditions such as:
- the default network was validated
- the default network was WiFi
- the default network was IPv6
- there was no default network
- ...
Most importantly, this new logging scheme allows to measure much more
reliably:
- the % of the time that a device had Internet, in the sense that the
default network was validated.
- the time transitions between default networks, keyed by previous and
new transports/link layer, which allows to derive wakelock durations
and wakelock power costs from default network switches.
This patch also simplifies the dumpsys interface of the connmetrics
service and reduces the commands to three:
- "flush" for metrics upload.
- "proto" for printing buffered event in text proto format.
- "list" for listing all events and statistics.

The "roaming" state of a network really belongs on NetworkCapabilities
instead of being published through NetworkInfo.isRoaming(). One major
reason is to support developers creating NetworkRequests for a
non-roaming network.
Watch for any capability changes that network statistics are
interested in (either metered or roaming) and notify it to perform
an update pass; fixes bug where we previously only triggered on
roaming changes.
Fix bug in VPNs where metered/roaming capabilities of underlying
networks weren't being propagated; this was probably preventing
some jobs from running over unmetered networks, and causing other
jobs to run over roaming networks! Also passes along link bandwidth
information from underlying networks, and propegates any changes
to underlying networks.
Fix race condition by reading prevNc inside lock. Utility methods
correctly calculate min/max link bandwidth values.

This patch takes advantage of the direct DefaultNetworkMetrics interface
between ConnectivityService and IpConnectivityMetrics and removes the
Parcelable interface from DefaultNetworkEvent.

This patch extracts the logging of DefaultNetworkEvent from inside
ConnectivityService and move it to a new DefaultNetworkMetrics class.
The DefaultNetworkMetrics is a singleton owned by the
IpConnectivityMetrics singleton implementing the metrics service for
core networking. ConnectivityService has access to this singleton via
LocalServices.
This class layout will allow to remove the Parcelable interface of
DefaultNetworkEvent and will instead let the IpConnectivityMetrics
service grab metrics from the DefaultNetworkMetrics directly.

Although commit 2a84d1cbcf fixed some flakyness issues in
testNetworkCallbackMaximum so that it became stable when ran on its own,
it introduced a new source of random failures because instead of
registering callbacks after callbacks until a limit was reached, commit
2a84d1cbcf changed the test logic to push the assertions right up to
the theoretical limit.
More precisely when registering and unregistering PendingIntents in a
loop, not introducing some delay for checking that previous
PendingIntents have been effectively unregistered can cause the test to
fail. This patch fixes this issue.

All of the input to IpSecService over the Binder
interface needs to be validated both for sanity
and for safety.
-Sanity check all the parameters coming from binder.
-Added setters for IpSecConfig to decouple the test
from the IpSecManager. This was needed because the
input validation caused the tests to fail due to a
null parameter that was previously un-tested.
-Added the mode flag to the IpSecConfig bundle this
oversight was found during testing.
-Expose the getResourceId() methods for testing in
UdpEncapsulationSocket, SecurityParameterIndex, and
IpSecTransform classes.
-Remove the unneeded getIpSecConfig() from
IpSecTransform: unneeded now that we can synthesize
configs.

Registered requests are not keyed by PendingIntents in
ConnectivityService, which means that unregistering a request with a
PendingIntent causes a linear search in all registered requests.
testNetworkRequestMaximum was registering too many PendingIntents
simultaneously, causing the unregistration loop to have n^2
complexity and to take a long time to take effect.
To make the unregistering loop less likely to trigger a timeout on
waitForIdle, this patch changes the test to not register MAX_REQUEST
number of PendingIntent, but instead mixes a small number of
PendingIntents with NetworkCallbacks to reach MAX_REQUEST number of
simultaneously registered requests.
When unregistering these requests, callbacks are unregistered first.
