It's good for Deserialize::Error to satisfy Send + Sync + 'static, as it can then be boxed into higher level errors. For objects passed from strings, we need to impose the similar bounds on the error type of standard trait FromStr. To this end, define a property trait FromStr, blanket-implemented with the new bounds.
Use utility traits defined in module chain_bounds to centralize bounds on the chain types necessary for the client implementation.

argh... this is very hacky... :/

rust-lang/rust#32722 does not allow just adding a subtrait with extra bounds on FromStr::Err.
