This patch takes the entire `wasmer-js` crate and merges it into the `wasmer` crate. Inside the `lib/api/src/` directory, there are 2 new directories: 1. a new `sys` directory, which contains the usual `wasmer` crate implementation, 2. a new directory `js`, which contains the implementation of `wasmer-js`. The `Cargo.toml` file is still compatible. The `default` feature fallbacks to `sys-default`, which enables the `sys` feature. All features related to compilers or engines or anything else prior this patch, activates the `sys` feature. Parallel to that, there is a `js-default` and `js` features. The `Cargo.toml` file is extensively documented to explain what are dependencies, dev-dependencies, features and other sections related to `sys` or to `js`. There is a bug with `wasm_bindgen_test` where it doesn't compile or look for tests in `tests/*/<test>.rs`. The hack is to name files `tests/js_<test>.rs`. Ugly, but it works.
