auto merge of #17753 : aturon/rust/error-interop, r=alexcrichton
This PR:
* Adds the error interoperation traits (`Error` and `FromError`) to a new module, `std::error`, as per [RFC 70](https://github.com/rust-lang/rfcs/blob/master/active/0070-error-chaining.md). Note that this module must live in `std` in order to refer to `String`.
Note that, until multidispatch lands, the `FromError` trait cannot be
usefully implemented outside of the blanket impl given here.
* Incorporates `std::error::FromError` into the `try!` macro.
* Implements `Error` for most existing error enumerations.
Closes #17747
