Support Unix domain sockets communication on Linux, MacOS and Android. Changes: 1. Add a field for InternetAddressType named unix. 2. Constructor of InternetAddress gains one more optional field: type. InternetAddress(String address, {InternetAddressType type}); 3. Add another constructor to InternetAddress which taks raw address/path for ip/unix addresses as an argument. InternetAddress.fromRawAddress(Uint8List rawAddress, {InternetAddressType type}); The operation for unix domain sockets communication is basically the same as normal sockets except an InternetAddress with type unix should be passed.
