Migrate resolver to use copy-free parser

This is a massive rewrite of the whole crate.

It separates out three crates:
fluent-syntax becomes a zero-copy AST+parser(+serialized in the future)
compabile with Fluent 0.8
fluent-bundle becomes aligned with fluent-bundle in JS
fluent becomes a top-level crate with added simple ResourceManager.

All of the code is compatible with current stable Rust 2018.
