add temporary results to async.series() functions

[tpetry]

By passing the actual result to each function in async series you would be able to use a fantastic code flow as followed:

// this would be any library function
function someFunctionReturningDatabaseObject(callback) {
    callback(null, dbResource);
}

async.series([
     db: someFunctionReturningDatabaseObject,
     query1: function(callback, results) {
         results.db.query('SELECT ....', callback);
     },
     query2: function(callback, results) {
         results.db.query('UPDATE .... WHERE .... = ?', results.query1.columnXYZ, callback);
     }
]);

With the actual async-code this is not possible, you have to use some variables in the scope where the async.series function will be called, the proposed backwards compatible change will allow much cleaner control flows

I'm not sure, but I think waterfall do just what you want

waterfall only passes the results to the next function. my proposal describes passing all results happend to every function.
