This makes the code easier to understand by making state
transitions more explicit. It also makes it easier to address a
TODO to turn the class into a StateMachine.
This should be an exact no-op refactoring. The current cases
covered by the code (all mutually exclusive) are:
1. requiresClat && !isPrefixDiscoveryStarted
Action: startPrefixDiscovery()
Equivalent to IDLE && requiresClat, because
isPrefixDiscoveryStarted returns true for every state except
IDLE.
2. requiresClat && isPrefixDiscoveryStarted && shouldStartClat
Action: start()
Equivalent to DISCOVERING && shouldStartClat,
because isPrefixDiscoveryStarted is true in DISCOVERING,
STARTING, and RUNNING, but start() does nothing if mState is
STARTING or RUNNING.
3. requiresClat && isPrefixDiscoveryStarted && !shouldStartClat
Action: stop()
Equivalent to (STARTING or RUNNING) && !shouldStartClat,
because isPrefixDiscoveryStarted is true in DISCOVERING,
STARTING, and RUNNING, but stop() does nothing if mState is
not STARTING or RUNNING.
4. !requiresClat && isStarted
Action: stop()
Equivalent to (STARTING or RUNNING) && !requiresClat,
because isStarted() is only true in STARTING and RUNNING.
5. !requiresClat && !isStarted && isPrefixDiscoveryStarted
Action: leaveStartedState()
Equivalent to DISCOVERING && !requiresClat, because
the only state with isPrefixDiscoveryStarted and !isStarted
is DISCOVERING.
Also, simplify case #5. In this case, calling leaveStartedState
is superfluous, because in the DISCOVERING state:
- There is no need to call unregisterObserver, since the observer
is only registered when entering STARTING and is unregistered
when going back to DISCOVERING or IDLE.
- mIface and mBaseIface don't need to be set to null because they
are only set to non-null when entering STARTING and nulled out
when going back to DISCOVERING or IDLE.

This just a rename with no functional changes at all. It is

In current design, entries with zeros are preserved after
addition/subtraction. These entries are not very useful
and lead to difficulty of verifying the result of
addition/subtraction.
However, change the behavior in the original NetworkStats
is considered risky in current stage.
Thus, this change provide a function that could remove these
empty entries in tests.

Added a new network capability TEMOPORARILY_NOT_METERED to support
the case that a network can temporarily become unmetered. This
allows carriers to deploy unmetered 5G network. When devices
camp on 5G network, this capability will be dynamically added
to the network and will be removed once leaving 5G coverage.

* changes:
Update CS helper for clearing NetworkCapabilities UIDs.
Simplify unregister logic for Connectivity Diagnostics callbacks.
Clarify comments for Connectivity Diagnostics reports.
Sort administrator UIDs for NetworkCapabilities.
Add combine() and equals() for NetworkCapabilities admin UIDs.
Use IBinder as key for ConnectivityDiagnostics storage in CS.
Decrement networkRequestPerUid when callbacks are unregistered.
Invoke onConnectivityReport on registering ConnectivityDiagnostics.
This change corrects the VpnProfile's maxMtu defaults to match that of
the Ikev2VpnProfile. 1400 is too high as a default, and Settings will
run into an issue here quite often.
