The old NetworkManagementService methods to start clatd threw
IllegalStateException, but the new netd methods throw
ServiceSpecificException. Update the catch clauses so that if
starting clatd fails, the system doesn't crash.
Also stop logging stack traces but only include the exception
message itself.

Currently NAT64 prefix discovery, which runs in netd, is started
by netd itself when a network is programmed with all-IPv6 DNS
servers. Unfortunately this is not correct because in many cases
we program DNS servers before the network is connected and it's
actually possible to send packets to them.
In general netd does not have enough visibility into network
lifecycle management to decide when to start and stop prefix
discovery. So move it into the framework with the rest of the
464xlat control plane.

Currently, both netd and clatd do NAT64 prefix detection, and we
start clatd on all IPv6-only networks regardless of whether netd
has detected a NAT64 prefix or not.
Instead, track the NAT64 prefix in the framework, and only start
clatd if the prefix is detected. This will allow us to remove
DNS64 detection in clatd, and pass the NAT64 prefix and the IPv6
address to clatd on the command line instead of clatd finding it
itself. That way, netd and the framework will always know how
464xlat is configured, and we'll be able to use that information
in netd.

Currently, NetworkAgentInfo keeps a Nat464Xlat object only on
networks where we're starting clatd (i.e., IPv6-only networks).
Simplify this code by making the Nat464Xlat object final and
always non-null. This allows us to use Nat464Xlat to store
information, such as the NAT64 prefix, even if the clat daemon
has not been started yet.
Also, remove the STOPPING state which waits for the interface to
be removed. Instead, when stop() is called, immediately enter the
IDLE state.
- This is necessary in order to be able to call start() again
before the interface removal notification has arrived.
- It's also arguably more correct than the current code,
because when stop() returns clatd has already terminated
(ClatdController::stopClatd calls waitpid), and thus the tun
fd is already closed and the tun interface is gone.
Also, now that Nat464Xlat objects are reused after stop(), add
test coverage for calling start() after stop, in both cases:
- The notification that the previous interface was removed
arrives before the second start().
- The notification that the previous interface was removed
arrives after the second start() but before the notification
that the second interface was added.
Also fix a couple of lint warnings.

1. Remove "throws Exception" from the signature so it can be used
in tests that do not already throw Exception.
2. Update comment to reflect the fact that TCP buffer sizes are
set on default network switch, not on connect.
3. Move into the method a class-level static constant that is
only used in that method.

The current logging relies on the system log that may rotate. This is a
problem to investigate bugs where the network stack service is not
started. Add a SharedLog to NetworkStackClient and dump it in
ConnectivityService (for lack of a better place to dump it).

Netd need the list of apps that have permission INTERNET or permission
UPDATE_DEVICE_STATS at run time to make decisions about application
request. To avoid protential deadlock and reduce the traffic between
netd and system server, Use packageManagerServcie to send the list of
apps that have those permissions to netd when device boot and when new
apps get installed.

Previously, they were only updated when underlying network set was
non-null.
This change also ensures that all the calls b/w ConnectivityService and
Vpn that leads to updating capabilities are on ConnectivityService
handler thread.
Additionally, it also ensures that capabilities are propagated after VPN
enters connected state.
This change also updates VPN capabilities inline from
ConnectivityService handler thread. Previously, there was an additional
loop where Vpn would update capabilities via NetworkAgent thru
AsyncChannel which posts back to CS handler thread, which could
potentially lead to delays in updating VPN capabilities.
