LinkProperties can represent way more complicated configurations
than what we can actually apply to interfaces. This makes it
error-prone to use it to represent static configuration, both
when trying to apply configuration coming from LinkProperties
and when trying to save configuration from current
LinkProperties.
Instead, move static configuration (IPv4 only, since we don't
support static IPv6 configuration) into a separate
StaticIpConfiguration class.

Add logic to obtain the mtu from the network PCO parameter and set it to kernel
when the mobile data connection is established. When there is no PCO mtu configured
from the network, the mtu size defined in the corresponding APN will be used. In case
no mtu size is defined for an APN used for data connection, the MCC/MNC based MTU
defined in the framework overaly will be applied.

This addresses a TODO and also makes it possible to create
routes to destinations that are not valid LinkAddresses, such as
multicast addresses.

This was old code I missed in previous inet condition refactor
and caused us to show "not connect" icon any time we connected
to a secondary network (mms/supl/etc).

Some devices use clatd for catching raw IPv4 traffic when running on
a pure-IPv6 carrier network. In those situations, the per-UID
stats are accounted against the clat iface, so framework users need
to combine both the "base" and "stacked" iface usage together.
This also means that policy rules (like restricting background data
or battery saver) need to apply to the stacked ifaces.
Finally, we need to massage stats data slightly:
-- Currently xt_qtaguid double-counts the clatd traffic *leaving*
the device; both against the original UID on the clat iface, and
against UID 0 on the final egress interface.
-- All clatd traffic *arriving* at the device is missing the extra
IPv6 packet header overhead when accounted against the final UID.

Switching from GCM-only inet condition reports to using our network
validation (captive portal check).
Note that currently the GCM signal is disconnected. Next step is to
make the bad-network report API trigger a re-evaluation of the network
and get negative reports from the NetworkMonitor.

We used to do this but the change got lost in the NetworkAgent
upgrade. This brings it back. ConnectivityService has netd do

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).

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.

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.
