Mangle a lot of names in macro expansion. (#53)

Browse Source 
* Mangle a lot of names in macro expansion.

To lower the chance of any issues, prefix idents in service expansion with __tarpc_service.
In future_enum, prefix with __future_enum. The pattern is basically __macro_name_ident.

Any imported enum variant will conflict with a let binding or a function arg, so we basically
can't use any generic idents at all. Example:

    enum Req { request(..) }
    use self::Req::request;

    fn make_request(request: Request) { ... }

                    ^^^^^^^ conflict here

Additionally, suffix generated associated types with Fut to avoid conflicts with camelcased rpcs.
Why someone would do that, I don't know, but we shouldn't allow that wart.

* Trim long macro lines
