* changes:
  [mdns] service-side impl for custom host
  [mdns] add API support for custom hostname

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.

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`.

This is a no-op change. Currently, the query mode employs a
boolean value to toggle between passive and active modes. To
accommodate a broader range of query modes for different
requirements, switch to an integer value that facilitating
the addition of new modes more seamlessly.

Use sec but not usec in the test. setsockopt TimeVal may lose precision
on usec when kernel rounds up the requested value based on the HZ setting:
val = tv.tv_sec * HZ + DIV_ROUND_UP((unsigned long)tv.tv_usec, USEC_PER_SEC / HZ);

Simplifies the CTS tests by testing only the first controller given
there is only one controller. No testing logic changes.

This commit also moves the helper methods to end of the file as they are
not the focus.

There are sometimes gerrit warnings on Android.bp file format:

This file is not formatted.

Run prebuilts/build-tools/linux-x86/bin/bpfmt -w {filename} to format the file, or apply the suggested fix.

This commit adds the suggested format script to make-pretty.sh to avoid
the warning.

Java code we wouldn't expect that stuff initialized in the

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.

Usually we can call InterfaceController.setIPv4Address API to add an
IPv4 address on the interface, in fact it ends up calling the native
Netd API which doesn't support setting deprecation/expiration time. In
user space we already have the netlink infra to send RTM_NEWADDR for
IPv6 address, extend the function to support IPv4 as well, then we can
deprecate the Netd API in IpClient.
