Review request for mesos. Repository: mesos Description ------- Whenever we currently need to get a `string` representation of `Error`s we explicitly access its `message` member. This makes it hard to use error-like types in generic contexts, e.g., inside `Try` or `Result`. This patch adds functions to stream and `stringify` `Error`s which can be used instead whenever a `string` representation is required. Custom error types can provide similar functions so that generic code can use this open interface instead of being tied to what `Error` provides.
