Christian Blichmann eb62bae167 Refactor stack trace handling 
- Drop `delim` argument from the `GetStackTrace()` family of functions.
  We only ever used plain spaces.
- Use an `std::vector<std::string>` for the symbolized stack frames and
  adjust the unwind proto accordingly.

This change now prints each stack frame on its own line while skipping
duplicate ones:

```

Sandbox2

Sandbox2 is a C++ security sandbox for Linux which can be used to run untrusted programs or portions of programs in confined environments. The idea is that the runtime environment is so restricted that security bugs such as buffer overflows in the protected region cause no harm.

Documentation

Detailed developer documentation is available on the Google Developers site for Sandboxed API under Sandbox2.

There is also a Getting Started guide for Sandbox2.
