Documents Byte#MIN_VALUE as being equivalent to a null score. This
enables scorers to pick a threshold below which a network won't be
used, by setting the score at any RSSI below that threshold to this
value.
Also adds an "RSSI boost" for the active network, so that we avoid
unnecessary switches between two closely-scored networks due to small
fluctuations in signal strength.

Added ConnectivityManager.removePendingIntentRequest(PendingIntent) as

We're starting to get network requests for specific SIMs
and the Legacy Type Inference was broken because the incoming
request included a network specifier while the legacy requests
it was compared with did not. Only compare the things we care
about.

This allows for a more streamlined UX in the current world, where
scorer apps are trusted (by virtue of being in /system/priv-app).
Trusted apps can continue to use the system dialog for consent, but
they may also set the scorer directly, under the assumption that they
are using their own consent UX to explain the feature to the user.

setDomain() and toLinkProperties() were not setting the domains.
The setDomain() bug affected Wifi and I believe the toLinkProperties()
bug affected Ethernet and Bluetooth reverse-tethering.

This is necessary/desired for two reasons:
1. UX around network scoring shipped with L despite lacking underlying
platform support. We do not want network scoring applications to
trigger this UX on L devices, and therefore we must break the contract
of what defines a network scorer so that apps build against the new
contract don't trigger the old UX.
2. As a start towards generalizing the term "score" for a potentially
broader role in the future, though that role is very much undefined.

If the kernel sends notification of an optimistic address then
treat is a useable address (isGlobalPreferred()).
Note that addresses flagged as IFA_F_OPTIMISTIC are
simultaneously flagged as IFA_F_TENTATIVE (when the tentative
state has cleared either DAD has succeeded or failed, and both
flags are cleared regardless).
Additionally: do not consider RFC 4193 ULA addresses sufficient
for "global preffered". They are, by definition, of global scope
but not sufficient for global reachability.

Also remove all "implementations" of addStackedLink and
removeStackedLink except the one in LinkProperties, because they

Specifically:
[1] provide a hasIPv4(), and
[2] a hasIPv6()
each of which requires an IP address, a default route, and
address-family-specific DNS servers to evaluate to true.
Additionally:
[3] redefine isProvisioned() to return the logical OR
of [1] and [2] above.
Any external caller can still use any of the has*() methods to
construct its own, different definition of "provisioned".

Most of this logic is simply removed from ConnectivityService.
The captive portal detection is now done by the NetworkMonitor.
The notification logic is still left in ConnectivityService as
it's used by both the NetworkMonitor and telephony's mobile
provisioning logic.

Now that we support unreachable routes, use those to block
address families on VPNs. This is a much more elegant solution.
Also update LinkProperties when IP addresses are added and
removed, fixing a TODO.

a ConnectivityManager function so they can be kept in sync.

Currently just valid/invalid based on NetworkMonitor findings.
Changed NetworkMonitor to start out in default state since starting in Offline causes
a spurious invalid report at creation time.

These APIs were added because we thought we needed them to provide
seamless transition from one server backend to another using local IP
addresses to distinguish between the backends. I.e., connections whose
local IP address was old would be routed to the old backend; connections
whose local IP address was new would be routed to the new backend.
It turns out that's not needed. VpnService already supports seamless
re-establishment, so VPNs just need to call establish() again with a
different IP address. I've verified with a custom VPN app that this
works, and can distinguish traffic based on the old and new addresses.
Nobody is using these APIs at the moment, so we could even consider
removing them altogether, but I prefer just hiding them, just in case.

Network Factories are allowed to go below, but networks need to be
constrained. Allowing the network to go below 0 meant that -1 could
sometimes leak through and foul the logic.
The core of 17361330 will be fixed when we stop sending scores for
listens to NetworkFactories, but it exposed this issue too. Summary:
1 - add a network listener. This isn't a request so it's not sent
to networks.
2 - alter your score (ethernet sets score to -1 when the link goes
down) (16:07:39.782)
3 - a bug in ConnectivityService causes score changes to get sent for
all network requests and network listeners causing NetworkFactories
to no see 2 entities. This bug will be fixed by a pending change
(https://googleplex-android-review.googlesource.com/#/c/540840/).
This causes the ethernet NetworkFactory to see two entities, both
served by networks of score -1. (16:07:39.989)
4 - disconnect Ethernet - this only sends 0 scores for known
requests, not network listeners. Had it been sent for both entities
they both would have evaluated that the networkfactory score (-1)
was lower than the request score (0) and both released their
refcount. (16:08:03.147)
5 - this means the listener is tracked by the EthernetNetworkFactory
with a score of -1 while the factory itself has a score of -1 so the
network release isn't called.
