simplify and improve canonicalize_name
- Replace scan and memmove with simple automaton - Convert forward to back slashes, lots of file systems treat them equivalenty, this saves us a few more checks down the road - Remove './' path components. We can saveley remove them in a string processing step instead of throwing an error. Also they actually appear often in tar balls, possibly not under user control.
