Keep track of requests as well as of networks that come and go.
This is necessary, for example, to ensure that we pretend that
HIPRI has gone down when the HIPRI request goes away, even
though the underlying cell network is actually completely
unaffected.
Also, ensure that when switching default networks we send
disconnect broadcasts (and do so *before* connect broadcasts, to
maintain the illusion).

There are some bugs where getActiveNetworkInfo gives bad data (seemingly)
and this will give the backing data in logs.

Removing ConnectivityService.NetworkFactory. This requires disabling
the ConnectivityServiceTest, but that's been broken since we stopped
using NetworkStateTrackers anyway.

Bypassable VPNs grab all traffic by default (just like secure VPNs), but:
+ They allow all apps to choose other networks using the multinetwork APIs.
If these other networks are insecure ("untrusted"), they will enforce that the
app holds the necessary permissions, such as CHANGE_NETWORK_STATE.
+ They support consistent routing. If an app has an existing connection over
some other network when the bypassable VPN comes up, it's not interrupted.

ConnectivityService has been rewritten for L and is in a stabilizing period.
We need the logging to track down bugs people report.
Restoring to Pre-L conditions.
If there's excess logging please report it - it probably indicates a bug.

When a network comes online, is a candidate for being the default network
(i.e. satisfies default NetworkRequest), and the device has no default
network, then make the new network the default network for the purposes
of routing network traffic. This does not affect NetworkRequests or
NetworkCallbacks. This ignores but does not affect network validation.
Benefits:
1. Offers a fail-safe in case network validation returns a false negative.
For example: It would be nice if every Android device didn't fail when
clients3.google.com/generate_204 went down.
2. Offers a method to debug connectivity issues.
For example: If WiFi is failing, disabling Cellular would rule out
interference from WiFi network validation.
3. Reduces delay between no connectivity and any connectivity.
4. Offers a fail-safe in cases of unreliable networks.
For example: You need rescuing from a remote location with a weak signal
offering 90% packet loss. You just want your distress call to go out
but are infuriated to find network validation blocks connectivity.

Don't rely on the NetworkAgent still being connected when we go to
hide the notification. The notification is hidden when the
NetworkAgent is disconnected so that wasn't a safe assumption.
By using the NetID as the notification identifier we also fix the
issue of multiple notifications of the same network type inadvertently
hiding the incorrect notification with the same network type.

This eliminates the need for the ConnectivityService.VpnCallback class.
This requires shifting VPNs to the new "network" netd API.
VpnService.protect() is modified to no longer go through ConnectivityService.
NetworkCapabilities is extended to add a transport type for VPNs and a
capability requiring a non-VPN (so the default NetworkRequest isn't satisfied
by a VPN).

Network validation prevents networks claiming to provide internet connectivity
from becoming the default network in cases where internet connectivity is not
found to actually exist.
If a captive portal is encountered the appropriate broadcasts and notifications
are surfaced to allow apps to handle signing in. If no app handles signing in,
my system app will handle it.

Make it all internal to ConnectivityService - we know when a network
is lost, so grab a wakelock then.
Moves the call out of WifiStateMachine which was grabbing at bad times
like every dhcp renewal or corp-network roam. These would always
go the full 1 minute and chew up battery.

In IPv4, a link is provisioned when DHCP succeeds. In IPv6, a
there is no such signal, because addresses and DNS servers can
be notified by the kernel at different times.
Add an isProvisioned method that returns true if we believe that
enough information has configured to use a network. For IPv6,
this requires an IP address, default route, and DNS server. For
IPv4, this requires only an IPv4 address, because we support
static configuration that doesn't have a default route or DNS
server.
To do this we use the existing hasIPv4Address method, rename the
all-but unused hasIPv6Address method to hasGlobalIPv6Address
(which is what we want anyway) and add new hasIPv[46]DefaultRoute
and hasIPv[46]DnsServer methods.

This change uses IpPrefix only in the public API and continues
to use LinkAddress for everything else. It does not change the
callers to use the new APIs, with the exception of changing
all current uses of getDestination to getDestinationLinkAddress
to make room for the new getDestination method that returns an
IpPrefix.
Based on Sreeram's earlier change:
https://googleplex-android-review.git.corp.google.com/#/c/477874/
but a bit simplified and with a bit more documentation.

1. Rename getNetworkPrefixLength to getPrefixLength. Update all
callers in frameworks/base and add a shim method and a TODO
for the rest.
2. @hide isSameAddressAs. It doesn't add much, and it's just
one-liner that callers can implement if they want.
3. Fix the alignment of the initial paragraph (<ul> should have
been </ul>).
4. Remove the documentation that talks about creating
LinkAddresses, since there's no public API for creating them.
With these changes I think LinkAddress is fine as a public API.
