[WIP] Rename crate remacs-lib and delete unused code

[brotzeit]

In emacs-ng we only use this crate for scan_rust_file. Since the code has to be executed before bindgen, we have to keep the header file that was introduced in remacs. I would appreciate if anybody has a better idea for the new name.

close #23

I think you will need to change configure.ac to use the updated library archive name

Yeah I know, that was the point when I pushed my changes and stopped working =)

Gotcha, sorry I missed the WIP in the title.

I like the naming changes, and I think this is good work. 👍

scan_rust_file function is now in crate lisp-doc. Unused code has been removed in master.
