The current query scan modes, active and passive, have
limitations. Unicast queries only originate from the first query
session, multicast queries should be sent simultaneously with
unicast, and both modes suffer from infrequent scans. To
address these shortcomings, a aggressive query mode is proposed.

* 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);

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.

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.
