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.
