MINOR: arg: Add an argument type to keep a reference on opaque data

The ARGT_PTR argument type may now be used to keep a reference to opaque data in
the argument array used by sample fetches and converters. It is a generic way to
point on data. I guess it could be used for some other arguments, like proxy,
server, map or stick-table.
