Register network callback for all networks and record
NetworkCapabilities for every networks. Once onDnsEvent is
triggered, use the netId it passes in to find the corresponding
NetworkCapabilities instead of using netId to create a Network
object(hidden API) then get the NetworkCapabilities by
ConnectivityManager#getNetworkCapabilities.

When registerDefaultNetworkCallback is called by an app that has
NETWORK_SETTINGS, the UID of the app is forgotten and the request
that is filed has an empty UID set. This results in that request
matching networks that have UID ranges that do not include it,
e.g., VPNs.
Fix this by ensuring that the UID ranges are properly set.

Currently, if a process with NETWORK_SETTINGS registers a default
network callback, its uid will be ignored and replaced with an
empty list of UIDs. This means it will incorrectly match VPNs
with any UID range.
Add a test for this bug to make it easier to review the upcoming
change that fixes it.

UidRange is used in a shared way between ConnectivityService
and VPN through the use of NetworkCapabilities. UidRange will
be part of the ConnectivityService mainline but Vpn.java will
stay in the framework. We need a way to replace the APIs using
UidRange, or to make UidRange system API. The only really
relevant surface here is NetworkCapabilities#{setUids, getUids}.
The need for UidRange could be replaced by an integer Range, so
replace the usage of UidRange by a integer Range in
NetworkCapabilities#{setUids, getUids} and update the relevant
callers.

Given that ConnectivityService is moving to a mainline module, we need
a @SystemApi for it to listen for changes in blocked status of an uid.
So, we decided to create a new API for this which can provide
ConnectivityService with more info about why an uid is blocked (which
will be useful for adding a new similar onBlockedStatusChanged callback
in CM.NetworkCallback) and also captures data saver restriction without
having out to track it separately.
Currently, NPMS does some redundant computations because we are
calculating both uid rules and blocked reasons separately. In a
follow-up change, we will compute uid rules using blocked reasons
and later possibly remove that onUidRulesChanged callback.

As attested by numerous TODOs in the code, a new way of
representing network quality and policy is needed instead
of an int.
An int representing the quality of the network requires
all parties using it to know how all other parties are
using it, and implementation details about the decision
algorithm. For all intents and purposes, the selection
is left to individual network factories who try to
achieve a desired result while piecing together all
possible states of the system.
As the number of such cases and desires increases, this
becomes both intractable and unmaintainable. Indeed, at
this time in the codebase nobody can really predict exactly
how a given change in score will affect selection across
the board, and it is essentially impossible to figure out
the behavior of network selection by inspecting the code
because the moving parts are scattered throughout the
entire codebase.
Having an object encapsulating policy and quality values
will let us centralize the selection and make it again
possible to maintain without knowledge of all behaviors
of all network factories. It will also provide better
guarantees of respecting policy, and allow bugfixes that
were not possible before because they'd touch too many
parts of the code.

Existing NetworkCallback users will get NetworkCapabilities with
location sensitive data removed (except for ownerUid which will be
added for existing apps for backwards compatibility). Apps
have to opt-in to receive location sensitive data.
Note: This was chosen because WifiInfo is the only TransportInfo tha
has location sensitive info & that was added only in Android 12. If we
choose to default to true, all existings apps retrieving
NetworkCapabilities for wifi networks will be blamed for location access
unnecessarily.
Changes:
i) Add a flag in NetworkCallback creation to retrieve
NetworkCapabilities with location sensitive info in their callback.
(More flags are being planned for NetworkCallback for throttling
callback frequency, etc)
ii) For NetworkCapabilities.getOwnerUid(), we will continue to send the
data for apps targeting older SDK (since this is an existing field and
the new flag defaults location sensitive data to off).

Rename StringNetworkSpecifier to EthernetNetworkSpecifier (its only
production user), and make it module-lib API.
The original StringNetworkSpecifier file is actually kept to satisfy
some invalid dependencies; it will be removed separately.
This allows specifying an Ethernet interface with a non-deprecated API:
until this change the only way to do so would be to use
NetworkRequest#setSpecifier(String), which is deprecated.
Similarly, add the TestNetworkSpecifier API for TestNetworkManager, to
replace previous usage of StringNetworkSpecifier. TestNetworkManager is
module API, so TestNetworkSpecifier should be module API too. This
allows tests to request the test interface specifically, without using
the deprecated NetworkRequest#setSpecifier(String).
