Crate ra_ap_proc_macro_srv

RA Proc Macro Server

This library is able to call compiled Rust custom derive dynamic libraries on arbitrary code. The general idea here is based on https://github.com/fedochet/rust-proc-macro-expander.

But we adapt it to better fit RA needs:

• We use tt for proc-macro TokenStream server, it is easier to manipulate and interact with RA than proc-macro2 token stream.
• By copying the whole rustc lib_proc_macro code, we are able to build this with stable rustc rather than unstable. (Although in general ABI compatibility is still an issue)…
