Generates sandboxes for C/C++ libraries automatically

Oliver Kunz 04ed89906b Adding AllowOpen to AllowLlvmSanitizers to avoid having to add AllowOpen in addition when it's only needed for running under the sanitizers.
In cases where SAPI users overwrite the default policy instead of extending it, the sandbox will fail with an `openat` violation. This is automatically inherited in the default policy.

The advantage with this implementation is that we don't expose the open* syscalls when not running under the sanitizers.

What is Sandboxed API?

The Sandboxed API project (SAPI) makes sandboxing of C/C++ libraries less burdensome: after initial setup of security policies and generation of library interfaces, a stub API is generated, transparently forwarding calls using a custom RPC layer to the real library running inside a sandboxed environment.

Additionally, each SAPI library utilizes a tightly defined security policy, in contrast to the typical sandboxed project, where security policies must cover the total syscall/resource footprint of all its libraries.

Documentation

Developer documentation is available on the Google Developers site for Sandboxed API.

There is also a Getting Started guide.
