Pass buffer size to netlinkSocketForProto to allow callers to specify
buffer size. The buffer size is not set if 0 is passed in.

Following callers of netlinkSocketForProto passes SOCKET_RECV_BUFFERSIZE
to keep same behavior as before:
 * OffloadHardwareInterface.createConntrackSocket()
 * NetlinkUtils.sendOneShotKernelMessage()
 * IpSecXfrmController.Dependencies.newNetlinkSocket()
 * InetDiagMessage.getConnectionOwnerUid()
Following callers pass 0 to not update the buffer size:
 * TunInterfaceController - it uses the socket only for writing
 * NetlinkUtils.createNetLinkInetDiagSocket() same behavior as before
Added a SOCKET_DUMP_RECV_BUFFERSIZE of 128k to be used by socket
requesting dump information from kernel:
 * NetlinkUtils.getAndProcessNetlinkDumpMessages() - sends dump request
   and expecting multiple reply messages.

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 helper doesn't really help...

all it does is a bpf map lookup and call a function on failure.

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.
