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.

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.

Update the NetworkAgent API for council comments
NetworkCapabilities needs to have its UIDs cleared (UID ranges, owner
UID, and administrator UIDs) before it can be shared with apps via
ConnectivityDiagnosticsCallback invocations. The previous helper used
for clearing these values mutated the provided NetworkCapabilities. This
is updated to instead return a sanitized copy of the provided
NetworkCapabilities

ConnectivityService is updated to simplify the logic for unregistering
ConnectivityDiagnosticsCallback instances. This change removes the given
callback from ConnectivityService's data structure. If the callback was
not registered with ConnectivityService, it is logged and the function
exits; else, the unregister() operation continues.

This change updates ConnectivityService to use IBinder instances as keys
when storing ConnectivityDiagnosticsCallbacks.
When storing ConnectivityDiagnosticsCallbacks in ConnectivityService,
the IConnectivityDiagnsoticsCallback is used as the key for
ConnectivityService.mConnectivityDiagnosticsCallbacks. However,
IConnectivityDiagnosticsCallback instances are received as different
objects. This causes them to produce different hashCode() values, so
attempts to remove an IConnectivityDiagnosticsCallback fail.

ConnectivityDiagnosticsCallbacks are tied to NetworkRequestInfo objects
when registered with the platform. Each NetworkRequestInfo is tied to a
specific uid, and ConnectivityService enforces a limit on the number of
network requests that can be associated with each uid.
When ConnectivityDiagnosticsCallbacks are unregistered from the
platform, their NetworkRequestInfo is freed and the number of network
requests per the user's uid should be decremented.

This change updates the behavior for registering
ConnectivityDiagnosticsCallbacks. Now, after a successful register()
call, callbacks will receive cached ConnectivityReports for all
matching, permissioned networks. This allows registrants to be updated
with the network state for their networks without having to wait for the
next network validation.
