Listen for mDns traffic in setuid sandboxed Utility process.
Local discovery listens for mDns traffic inside Utility process with enabled setuid sandbox (seccomp-BPF is not enabled). Setuid sandbox fails ::socket calls. To overcome this we use LocalDiscoveryMsg_SetSockets IPC message to pass two new UDP sockets created in browser process. These sockets will be provided for net::MDnsClient using net::PlatformSocketFactory.
Added check to make sure that only Local Discovery Utility process handles LocalDiscovery* IPC messages.
This code, as well as Windows version, is not executed without --enable-device-discovery switch.
