Christian Blichmann 5c98e30ef2 CMake: Force inclusion of exported functions in add_sapi_library() 
Newer versions of the GNU gold linkers sometimes omit the symbols for
sandboxed functions, leading to errors like `function not found` when
Sandboxed API tries to call them at runtime.

The fix is simple: Do what Bazel does and wrap the static library in
a `-Wl,--whole-archive`/`-Wl,--no-whole-archive` pair.

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.
