Richard W.M. Jones 39d1a7dbc9 generator: Use a struct instead of a tuple to describe each action.
Each action changes from a tuple like this:

  ("cat", (RString "content", [Pathname "path"], []), 4,
   [ProtocolLimitWarning],
   [InitISOFS, Always, TestOutput (
      [["cat"; "/known-2"]], "abcdef\n")],
   "list the contents of a file",
   "[...]");

to a slightly longer but more readable struct:

  { defaults with
    name = "cat";
    style = RString "content", [Pathname "path"], [];
    proc_nr = Some 4;
    protocol_limit_warning = true;
    tests = [
      InitISOFS, Always, TestOutput (
      [["cat"; "/known-2"]], "abcdef\n")
    ];
    shortdesc = "list the contents of a file";
    longdesc = "[...]" };

["defaults" is a struct which contains the defaults for every field,
allowing us to use the "{ defaults with ... }" syntax to just update
the fields we want to be different from the defaults.]

This is a mechanical change and there is no change to the output of
the generator.  I checked the output before and after with diff to
verify this.  There are no changes in the output apart from UUIDs
which are expected to change with each run.
