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).

These were broken by aosp/1553463, which made filterNetworkInfo
unconditionally call setDetailedState with a reason of "" and an
extraInfo of null.
Fix both synchronous getter APIs (e.g., getNetworkInfo) and
CONNECTIVITY_ACTION broadcasts by calling a new
filterForLegacyLockdown method that behaves similarly to how the
now-deleted LockdownVpnTracker#augmentNetworkInfo used to behave.
While I'm at it, move back to private a method that was public
only because LockdownVpnTracker used it.

This makes the test more realistic, since telephony always puts
the APN name in the extraInfo field. It also makes it easy to
test that various APIs properly return the extra info without
plumbing a new parameter through TestNetworkAgentWrapper,
NetworkAgentWrapper, and InstrumentedNetworkAgent.
Also make the extraInfo and the legacyType available to tests.
This will be used in future tests that assert the contents of
extraInfo.

[PhoneStateListener] Redesign PhoneStateListener: Use TelephonyCallback
NetworkAgentInfos cache the list of requests they satisfy,
and that list is used to send callbacks. Therefore, when
the TRACK_DEFAULTs are copied, this list needs to be
updated.
The best way to do this is to figure out what was the old
active request and find which requests corresponds to it
in the new list, and then upon registering adding the
active request to the relevant satisfier if present.
A few other ways can be considered like replacing the
request as it gets added, but this would temporarily
increase the number of callbacks allocated to the app
and risks crashing it for no good reason ; furthermore
the call to remove would have to be eschewed somehow
for those requests that are replaced. This is much
simpler.
Test: new test for this. This also passes the future
tests for per-profile default network preference.

The test is currently flaky as broadcasts can take a long time
to be delivered, often more than 500ms.
Extend the timeout for broadcasts to 30s.
Historically the test would wait for broadcasts for at most 500ms,
but not verify that they were received before proceeding. This was
fixed recently by adding an assertion, but the assertion needs to
give enough time for the broadcast to be received.
