capture stacktrace on error Status/StatusOr?

[alkis]

Provide a way for erroneous Status/StatusOr to capture the stacktrace at creation time and a way to access/render it as string.

Additionally could there be a way to chain error status together? Sometimes it is useful to wrap/rewrite an error with another because more context is available at the caller. Allowing chaining the low level error to the rewritten one would be very useful to increase the fidelity of errors/error messages.
