make_arg_list() builds an array of typed arguments with their values, that the caller describes how to parse. This will be used to support multiple arguments for ACLs and patterns, which is currently problematic and prevents ACLs and patterns from being merged. Up to 7 arguments types may be enumerated in a single 32-bit word, including their number of mandatory parts. At the moment, these files are not used yet, they're only built. Note that the 4-bit encoding for the type has left only one unused type!
