Subject: Add support for the self path

This keyword is described in
https://doc.rust-lang.org/std/keyword.self.html

Which allows it to refer to the current module when used as the first
segment. If the keyword is used as any other segment it leads to a
confusion between self the local parameter keyword in methods. Rustc
emits a generic unresolved segment error in that senario which I have
adopted here.

Fixes #1227
