Currently netd supports only the default value for VPN but CS
send priorty value 1 to netd. It will break the default routing
for VPN. Thus, update network preference priority value to 0 for
VPN.

This ensures classes are used from the service-connectivity jar, instead
of using classes from the system_server bootclasspath when there is a
name conflict.
Any developer adding a future class should do so in a subpackage of
com.android.connectivity (such as com.android.connectivity.server).
Otherwise, jarjar rules need to be added manually until b/180995093 is
fixed.
Also update current jarjar rules so that classes are jarjared to
com.android.connectivity.[original name], making it easier to find the
original source. This is consistent with the wifi module.

dexdump on service-connectivity.jar shows no classes outside of
com.android.connectivity and com.android.server

- Remove ipv4MappedAddressBytesToIpv4Address because it can be covered
by parseIPv4Address.
- Remove IllegalArgumentException from parseIPv4Address because it has
never happened
- Reverse the order of upstream and downstream timeout refreshing in
refreshAllConntrackTimeouts for readability because both source and
destination of the downstream are opposite direction to the
upstream.

Internal utils are generally jarjared by connectivity jarjar rules, but
ArrayUtils is not actually statically linked into the tests, so this
makes the ConnectivityCoverageTests fail. FrameworksNetTests has been
fine because it does not use jarjar, but does not exercise updated code
because of that.
Remove usage of the hidden utility, as there are reasonable alternatives
with non-hidden APIs that avoid other breakages long-term.

Rename net-module-utils-srcs to connectivity-module-utils-srcs.
This is done as the module utils are made specific to
service-connectivity to contain only classes used by
service-connectivity.

When NetworkRequestInfo#binderDied is called in ConnectivityService,
only pass the NRI to handleRemoveNetworkRequest. This is to prevent a
potential crash when unlinkDeathRecipient is called twice for the same
NRI.
Also, as a cleanup, don't iterate mRequests in the log message on binderDied.
As per the bug, the chain of events leading to a potential crash are:
- `Connectivity.NetworkRequestInfo#binderDied()` is called for an NRI
tracking multiple `NetworkRequest` items. This can happen for a TRACK_DEFAULT
request filed by a UID on a different preference than the default, which
copies the request list.
- This in turn triggers multiple `EVENT_RELEASE_NETWORK_REQUEST` events
for the same NRI, one for reach `NetworkRequest` tracked.
- When handling `EVENT_RELEASE_NETWORK_REQUEST`, each `NetworkRequest`
that is passed in will then be used to look up the parent NRI that originally
sent it to be released.
- Therefore if an NRI was tracking three requests, it would trigger three
release network events, then each request would be used to look up the
same NRI again when handling said release event.
- Finally, `ConnectivityService.NetworkRequestInfo#unlinkDeathRecipient` is
called for the NRI in question. Using the scenario above, that means we could
call `unlinkDeathRecipient` multiple times for the same NRI if it was tracking
multiple network requests causing the associated crash.
- If `unlinkDeathRecipient` is called more than once for the same NRI, it will
cause the crash listed in this bug.
- The fix is to only call handleRemoveNetworkRequest for the NRI once. This
works since when removing the NRI, we iterate over all of its requests to
remove them. By only calling handleRemoveNetworkRequest once, it's ensured
`unlinkDeathRecipient` for this NRI as part of
`Connectivity.NetworkRequestInfo#binderDied()` is only called once and not
potentially multiple times.

registerSystemDefaultNetworkCallback no longer throws
UnsupportedApiLevelException as it has compatibility behavior down to Q,
so remove the catch clause for the checked exception.
The exception would previously not be thrown since the Tethering module
is only running on R+.
