aosp/2605757 updated isDefaultNetworkActive returns false when there is
no default network.
But this change was not merged to U release branch and this change was
not well tested by dogfooding.
So this CL reverts the isDefaultNetworkActivity behavior change.

Reason for revert: b/288450518
Some iterations over mNetworkAgentInfos result in networks being
disconnected, which removes them from mNetworkAgentInfos during
iteration. This crashes with NPE or OOB exceptions.

When a network was explicitly selected, the user just tapped it and
is likely waiting for it to connect. A shorter timeout is therefore
more appropriate for these.

This CL changes the behavior as follows.
Before this CL, isDefaultNetworkActive returns true if there is no
default network.
After this CL, isDefaultNetworkActive returns false if there is no
default network on all releases.
Before this CL, LegacyNetworkActivityTracker does not call
onNetworkActive callback for networks that tracker does not add the idle
timer to (e.g. ethernet, cell network configured with activity tracking
disabled).
After this CL,
On T-, onNetworkActive keeps the current behavior.
On U+, onNetworkActive is called regardless of the idle timer existence. This behavior is consistent with ConnectivityManager#isDefaultNetworkActive, which always returns true for a network that has no activity tracking.

Following CLs update LegacyNetworkActivityTracker to support multiple
network activity tracking on U+ devices.
This CL is a preparation for them.
Reasons for having locks in LegacyNetworkActivityTracker were 1)
mNetworkActive can be updated from non handler thread 2)
isDefaultNetworkActive can be called from non handler thread and this
return boolean based on mNetworkActive and mActiveIdleTimers.
aosp/2606673 moves the activity change processing to handler thread
and resolved the first reason.
This CL updates isDefaultNetworkActive to just return
mNetworkActive and resolved the second reason.
So, now LegacyNetworkActivityTracker doesn't need locks and this CL
removed the locks.

Currently, various codepaths in ConnectivityService disconnect
networks using NetworkAgentInfo#disconnect. This posts a message
to the NetworkAgent to disconnect and also posts a message to
ConnectivityService to call disconnectAndDestroyNetwork, which
performs all cleanup in ConnectivityService. These two messages
race and the order is non-deterministic.
Instead, always disconnect using disconnectAndDestroyNetwork,
and have disconnectAndDestroyNetwork post the message to the
agent to disconnect.
This fixes a bug where if wifi uses unregisterAfterReplacement
twice in quick succession, when the third agent connects it
doesn't work because the interface is still being used by the
second network.
Also remove the import of IllegalArgumentException to keep the
linter happy (java.lang.* never needs to be imported).

One of the reasons for having locks in LegacyNetworkActivityTracker is
mNetworkActive is updated from non handler thread.
aosp/2606673 moves network activity change processing to handler thread.
All the methods that update mNetworkActive and mActiveIdleTimers should
be called from handler thread now.

IdleTimer tracking can be disabled if configured timeout is 0 or
negative value.
In this case, setupDataActivityTracking does not add idleTimer and
removeDataActivityTracking causes NPE.
This did not cause crash since the code to cause NPE is wrapped by try
catch.
This CL adds check to avoid causing NPE.

aosp/2162425 added a WTF if a NetworkAgent changed state before
its native network has been created. This was intended to apply
only to the new U+ codepath, where networks are always created
immediately as soon as their agents register them. But the WTF is
logged on pre-U devices as well.
Fix this so that the WTF is only logged when the new codepath is
running.

See system/netd/include/Fwmark.h which reserves the bottom 21 bits
of skb->mark for netid, etc... so out of necessity these have to be
in the top 11 bits.
In practice the only values that really make sense are either:
mark == mask == 0 (disabled)
or (mark == mask) being one of the top 11 available bits, for example:
mark == mask == 0x80000000 (enabled, using top-most bit)
(only a single bit makes sense, as this is really just a boolean signal,
and only the topmost is known to be used on any real devices)
Let's just force the use of 0x80000000 for ecosystem consistency.

Currently, native networks for non-VPN networks are created only
when the NetworkAgent goes into the CONNECTED state. This is not
ideal, because until the network is connected:
- Nothing routes to the network, so no IP packets can be sent on
it (except via packet sockets).
- Many network configuration changes (e.g., routes and DNS
servers) fail to apply because the network does not exist yet.
These cause ENONET errors in the logs.
Fix this starting in U by creating the native network as soon as
the agent registers. This should not impact apps because
NetworkCallbacks are not sent until networks are connected.

From service-connectivity, NAMESPACE_TETHERING must be used, as
NAMESPACE_CONNECTIVITY is used for the NetworkStack module. Also the
isFeatureEnabled with module name must be used, otherwise the "android"
package version is queried instead of the tethering module version.
BpfNetMaps is using flag value 1 to workaround this issue.
flags in NsdService, AutomaticOnOffKeepaliveTracker, and ConnectivityFlags
were not pushed currently.
So, this change has no effect to devices.

The ConnectivityResources class is only usable with QUERY_ALL_PACKAGES
permission, so it is not generally usable in framework-connectivity. It
is also backed by the ServiceConnectivityResources APK, which is
intended as resources for service-connectivity.
Move the class to service-connectivity and update callers. CTS needs a
way to determine the supported keepalive count as it used the
resources from KeepaliveUtils as @hide API, so provide a
ConnectivityManager @hide API for testing.

This is a clean up commit to correct the javadoc of
NetworkAgent.CMD_START_SOCKET_KEEPALIVE. This event was used
between ConnectivityService/NetworkAgent, and also
ConnectivityService/KeepaliveTracker with different semantics.

so also separate the usage to different events.
Also move the event definitions together so that a new event
