3f18aa996d Refactor the Nat464Xlat function for simplicity.
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.

70897531b8 Update CS helper for clearing NetworkCapabilities UIDs.
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

970e77957c Simplify unregister logic for Connectivity Diagnostics callbacks.
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.

0c55a30a9e Use IBinder as key for ConnectivityDiagnostics storage in CS.
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.

fc14fbea61 Decrement networkRequestPerUid when callbacks are unregistered.
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.

905b475a00 Invoke onConnectivityReport on registering ConnectivityDiagnostics.
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.

21c26dae4e Fix addRoute replace default route unexpectedly
In aosp/1203789, if two routes are with the same destination,
it will be replaced instead of added when calling addRoute.
This breaks scenarios which rely on the ability to add multiple
default routes, such as multiple IPv6 default routes learned
via address autoconfiguration.

This change treats the route is an update if the destination
and nexthop are the same, but different in other properties.

924fb4c08e Shorten the output of NetworkAgentInfo#toString().
Currently, printing a NetworkAgentInfo results in a very long

- Not printing a number of fields in NetworkInfo that are no
  longer used.
- Instead of printing flags regardless of whether they are true
  false, only print ones that are true. For example, this changes
    everCaptivePortalDetected{true} lastCaptivePortalDetected{false} captivePortalValidationPending{false}
  to:
    everCaptivePortalDetected
- Only printing clat information if clatd is started.

Also, put the long and variable-length fields lp and nc at the
end of the output.
