MAC address parsing in constructResourceObject()

MAC address parsing in constructResourceObject()

When call the function constructResourceObject(..), the first parameter
is a string for a host address of the server.
The string could be a IPv4 form or IPv6 or MAC.
But there is no parsing logic for MAC address form(xx:xx:xx:xx:xx:xx).
Without this, MAC is parsed as IPv4 which does not work properly.
(the first block as IP address, the second one is port number, and
lasts are ignored)
So I added the MAC parsing logic with checking a validity of address.
