Abstract FilePath Proposal

[Alois Cochard]

+1 for the first two phase of the original proposal. I always wished it was
not a type alias.

No strong opinion of phase 3, I have propabaly never run into sophisticated
enough issues to fully get the picture... but I doubt we'll be able to
craft an ideal cross-platform API, I like what is in spirit in the original
proposal.
