Nick Craig-Wood 144c1a04d4 fs: Fix parsing of paths under Windows - fixes #2353
Before this copyto would parse windows paths incorrectly.

This change moves the parsing code into fspath and makes sure
fspath.Split calls fspath.Parse which does the parsing correctly for

This also renames fspath.RemoteParse to fspath.Parse for consistency
