aconfig soong modules should be used to read the trunk stable flag.
However they are not available in the mainline branch.
So this CL adds the method to check if the trunk stable flag is enabled
or not by directly reading from DeviceConfig.
It's expected that this does not work correctly if flag value is not
stored in the DeviceConfig.
But for the time being, this method can be used to keep development.
Once the mainline branch supports the aconfig soong modules, method
added by this CL must be removed and java_aconfig_library should be
used instead.

Test: adb shell device_config put android_core_networking \
Test: com.android.net.flags.test_feature true

aosp/2724918 moved processing netd events for 464xlat to the
handler thread.

This CL makes 464xlat run the code that processes those events
inline. This simplifies the code and makes the ordering of events
more similar to what it was before.

The issue seems to be that some other network may become
available or change capabilities before Lost happens, as
can be the case with real networks like in CTS.

Because followup changes will stop using synchronous getters
for getting the service package UIDs, it will be a lot more
convenient if this array is automatically sized.

* changes:
  Block the package updater while CTS are running
  Add a command to block networking for an app

This adds support for additional protocols and also provides more clear
semantics of protocol specific fields, such as only including tcpFlags
when the protocol is IPPROTO_TCP.

This change refactors BundleKey to be a separate struct. This allows
us to do the conversion (e.g. of sport/dport, or icmp fields in the
future) in the constructor and change types (use optionals) where it
is convenient to simplify the code.

This change also fixes a bunch of desigated initializer order warnings
in the test (fields should be declared in same order as defined).

Tests are sometimes run on hardware devices with wrongly configured wifi
or cell data. Ensure that this is reported as an infra error, and not a
test error, so the root cause is easier to identify.

After this change, all synchronous state machine functions are
implemented.
There are some intentional limiations:
1. Allow setup states before machine thread started or inside machine
   thread but states can only be setup once before calling #start.
2. The behavior of transitionTo is defined so that the destination
   state can never change during state transitions. Once a destination
   has been specified, it cannot be changed until the previous state
   transition is complete. In other words, SyncStateMachine does not
   support calling transitionTo in State enter or exit.
3. Support sendSelfMessage in State#processMessage(), #enter() and
   #exit(). This allow automaton to decide the follow up action by
   itself. For example: if something wrong happens during state
   transition, the implementation can enqueue an error message then
   process the error message after finishing the current state
   transition.

Although the launcher should be visible due to the <queries> declaration
in the manifest, there are sometimes flakes indicating that the access
to the package was blocked due to visibility rules.

Try adding QUERY_ALL_PACKAGES to see whether it resolves the flakes.
