All AIDL interfaces need to be a stable version in release branch.

Mark @Deprecated in mdns_aidl_interface functions in the latest unstable
version.

Per API council feedback and API guideline at
go/android-api-guidelines#provide-executor, it should call
Binder.clearCallingIdentity() before invoking the app-supplied callbacks
so that the app doesn't use the system-server's identity for permission
check in the callback.

- Change class names to start with Xfrm or StructXfrm for consistency
  with other messages and structs
- Create xfrm sub-folder for xfrm messages
- Add "finals" to input parameters

It's no longer needed because the only useful version is v1 and all
functions are deprecated in v2.

The NsdManager constructor creates a new thread, which is not
intended to be closed. However, the test in NsdMangerTest and
NsdServiceTest create a new NsdManager instance, resulting in a
large number of threads running during the tests. This can lead
to an out-of-memory error for the tests. To resolve this issue,
use the common singleton thread ConnectivityThread to handle
tasks from the various instances.

Instead of passing state machine to UpstreamNetworkMonitor, wrapped it
by an interface would have two benefits:
1. Easier for testing.
2. Isolate state machine operation in callback.

The only version of mdns_aidl_interface supported by Netd is V1. After
that, the entire interface has been deprecated (which is the V2). The
latest stable version is no longer meaningful because no one is supposed
to use V2.

TetherUpstream6Key#src64 should be stored in network order. Use
a big-endian ByteBuffer to retrieve a value stored in network order
is actually converts it into native order, which is little-endian in
Android.

In this CL, we changed it to use byte[] instead of long to store the
top 64-bits of the source prefix.

* changes:
  Rename hasCarrierPrivilege... to isCarrierServiceUid...
  Detect discrepancies in subIds
  Allow carrier service UIDs to access their own WiFi networks.

Bug: 308519360
Test: CarrierPrivilegeAuthenticatorTest
Change-Id: I59164be00a9e1fcced8538537c1dcabd214f2170

This method tests whether the UID is the carrier service
UID, not whether the UID has carrier privilege.

Note that in normal operation, the carrier service UID always
has carrier privilege.

The subIds in network capabilities are stored both in
the network specifier (for telephony) or transportInfo (for
wifi), and in a separate field in NC, which are seeded
differently. These should in principle never diverge if there
is no bug in the network factories code, but since this code
is OEM-specific, it's very hard to know whether it's the case.

Historically CarrierPrivilegeAuthenticator has been using the
specifier / info to find out about the sub id, but reading
from NetworkCapabilities#getSubscriptionIds() would be both
nicer and more future-proof. Log a terrible failure in case
they differ, so we can confidently switch to the latter if
we don't see any such log.

This tests that the network providers are subject to appropriate
limitations as to what they can set as allowedUids – both in the
positive (can do) case, and the negative (can't do) case.

This change only outputs thread count differences instead of
listing all threads. Additionally, it ignores threads with 1
count, which effectively filter out threads created
by the test runner or other system components, such as
hwuiTask*, queued-work-looper, SurfaceSyncGroupTimer,
RenderThread, and Time-limited test.
