Construct the network address for the given \c hostname and \c port.

it's used, otherwise it's used as a host name. If \c hostname ends
in ":[0-9]+" then that suffix is extracted and used as the port,
overridding the port parameter. The resulting port must be a valid
port number (zero is not a valid port number) otherwise \c XSocketAddress
is thrown with an error of \c XSocketAddress::kBadPort. The hostname
is not resolved by the c'tor; use \c resolve to do that.
