Matt Caswell 61dfe3a720 Change functions to pass in a limit rather than calculate it 
Some extension handling functions were passing in a pointer to the start
of the data, plus the length in order to calculate the end, rather than
just passing in the end to start with. This change makes things a little
more readable.
