Literal ip4/6 addresses in VCL

Thank you for pointing this out, so I am going to implement this syntax for the 
case where runtime conversion is needed.

Do you have an opinion regarding the suggestion for the VCL compile time case?

IOW, do you favor

	set client.ip = [123.45.67.8];
or
	set client.ip = "123.45.67.8";

or even no compile time support as in

	set client.ip = IP("123.56.78.9");

Thanks, Nils
