The current implementation contains a bug that an updated
registration may be checked for conflict with itself. In this way
it will get renamed although its not a real conflict.

Bug: 283053491
Change-Id: I9b717c1a389bd92b8cffa9fe3f58e921609bd79b

This CL also adds a test case that the hostname is renamed due to a conflict
after probing succeeded.

This commit adds support of regsitering a service with a custom
hostname. This is required to enable Advertising Proxy feature for Thread
devices.

For example:
```
NsdServiceInfo info = new NsdServiceInfo();

info.setServiceName("My Service");
info.setServiceType("_test._tcp");
info.setHostname("MyHost");
info.setHostAddresses(List.of(address1, address2));

nsdManager.registerService(info, PROTOCOL_DNS_SD, listener);
```

This CL also adds two new error codes for service/host registration
conflict: `FAILURE_SERVICE_NAME_CONFLICT` and
`FAILURE_HOST_NAME_CONFLICT`.

* changes:
  Add service implementation for ThreadNetworkController#setEnabled
  Add setEnabled API

ThreadNetworkControllerService handles setEnabled requests and
asks ot-daemon to enable/disable Thread. The desired Thread enabled state
is saved in thread persistent setttings, the setting is loaded at bootup.

setEnabled API is added to ThreadNetworkController, this
can be used by applications with privileged permission to set
Thread to enable/disabled state.

The Thread enabled state can be subscribed with
ThreadNetworkController#registerStateCallback.

When Thread is disabled, the join/scheduleMigration APIs will
fail with ERROR_THREAD_DISABLED.

When Thread is disabling, all commands will fail with ERROR_BUSY.

  [mdns] add API for discovery with subtype

The Thread country code should be a 2-Character alphabetical country
code. The `00` is an invalid country code for Thread country code,
but it is the default country code for WiFi country code. If setiting
the `00` as the Thread country code, the ThreadCountryCode throws
an exception.

This CL checks whether the country code is a valid Thread country
code before setting the WiFi country code as the Thread country code.

This commit adds support of discovering services with explicit subtype.

With this change, a service can be discovered with subtype with:
```
nsdManager.discoverServices(
        new DiscoveryRequest.Builder("_http._tcp", PROTOCOL_DNS_SD)
	        .setSubtype("_printer").build(),
	executor, listener);

NewApi is a lint check that you don't call framework methods that were
introduced in versions later than your min_sdk_version. We want to
make this an error, so we're baselineing all existing issues.

This cl was generated automatically, by taking all the NewApi issues
from the reference baselines, and all the non-NewApi issues from the
existing checked in baselines.

java_sdk_library modules should specify the aconfig_declarations modules
in order to generate the exportable stubs (i.e. the stubs that exclude
the disabled aconfig flags) by providing the information about the
aconfig flag values.

The exportable stubs will be used when generating the module sdk
snapshots and to generate the hiddenapi flags, in order to prevent
exposing the disabled apis in runtime.
