Address comments on aosp/1539753, aosp/1542487 and aosp/1547496.
Fix propagating underlying caps when a network disconnects.
Test for bugs with suspended VPN underlying networks.
CaptivePortalData only has 7 fields on R, not 8.

aosp/1513052, which generalized support for underlying networks,
broke default network switching when the network underlying a VPN
disconnects.
This is because it calls propagateUnderlyingNetworkCapabilities
in the middle of the bookkeeping operations needed when a
network is disconnected (specifically, after all satisified
requests are removed from the disconnecting network, but before
mDefaultNetworkNai is updated). This is completely incorrect
because propagateUnderlyingNetworkCapabilities can trigger a
network rematch, and running a rematch when the request data
structures are inconsistent is obviously wrong. See the test
changes in this CL for an example of the damage.
Fix this by moving propagateUnderlyingNetworkCapabilities to
before the bookeeping operations begin. It must be before
mDefaultNetworkNai is updated, because otherwise it will not know
that the default network is disconnecting, and it will not be
able to propagate capabilities to VPNs that set underlying
networks to null (i.e., to the default network). It must be
after the nai is removed from mNetworkForNetId because
otherwise it will think that the underlying network is still
connected.

This will be mainly used by VCN management service which will
need to hold the networks but preserve the backgrounded-ness
of the networks.

This test flakes about 1% of the time on my device. This is due
to the test calling expectNetworkRejectNonSecureVpn() before the
handler thread has processed the call to setAlwaysOnVpnPackage.
Fix this by waiting for callbacks where it is possible to do so,
and by calling waitForIdle where it is not.

Code review comments have suggested that this test is too long
and difficult to understand. Split it into two tests and put some
of the common setup into setup methods and statics.

These fields have been recently audited, confirmed never to be
null, and annotated @NonNull. Ensure that they can never become
null by throwing exceptions in the codepaths that set them.
Also remove some null checks.

If IOException happens while trying to start keepalives sockets,
an invalid fd will be constructed. It will fail with
ERROR_INVALID_SOCKET if the user later calls start(). Current
design to construct the invalid fd use the hidden
ParcelFileDescriptor constructor which will not work for the
incoming ConnectivityService mainline. Thus, replace it with
the other formal API.

1. network cannot be null because it's final and the only caller
of the constructor passes in a fresh copy.
2. linkProperties cannot be null because:
- The only caller of the constructor passes in a fresh copy.
- The only assignment to nai.linkProperties is in
updateLinkProperties, and that dereferences newLp a few
lines before assigning it.
3. networkCapabilities cannot be null because:
- The only caller of the constructor passes in a fresh copy.
- There are no direct assignments to nai.networkCapabilities.
- All 4 assignments happen via getAndSetNetworkCapabilities:
- registerNetworkAgentInternal, updateCapabilities and
applyBackgroundChangeForRematch all pass in the return
value of mixInCapabilities, which is always non-null.
- updateNetworkInfo re-assigns the capabilities that were
already set in the object.
4. networkAgentConfig cannot be null because it's final and
the only caller of the NetworkAgentInfo constructor passes
in a fresh copy.
Address a TODO in ConnectivityService to remove a check for the
nai's capabilities being null.
Also fix a style nit pointed out by the linter.

This is a port of the exemption that exists in WifiPermissionsUtil.
Settings, sysui, network stack needs to be able to access all network
state regardless of location toggle. If we want to move sysui, etc to
retrieve WifiInfo via NetworkCapabilities (which is the current plan),
this exemption is essential since UI should reflect wifi state
regardless of location toggle state.
