Christian Blichmann f44cca6c98 Fix path to generated proto sources when embedding 
When embedding SAPI in an external CMake project, the version of
`protobuf_generate_cpp` that we lifted from upstream protobuf produces
the wrong generated file paths.

For example, given this project structure:

```
/parent/
+-- myproject/
+-- myproject_build/  <- CMake build directory
+-- sandboxed-api/    <- Checkout from GitHub
```

And a CMake file in `myproject/CMakeLists.txt` that embeds SAPI like
this:

```
cmake_minimum_required(VERSION 3.12)
project(SandboxedTest LANGUAGES CXX)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

add_subdirectory(
  ${PROJECT_SOURCE_DIR}/../sandboxed-api
  ${PROJECT_BINARY_DIR}/sandboxed-api
)
```

Then `protobuf_generate_cpp` correctly invokes the protoc compiler to
generate
`/parent/myproject_build/sandboxed-api/sandboxed_api/proto_arg.proto.pb.cc'.
However, the path of the generated source file that is passed to the C++
compiler will be
`/parent/myproject_build/sandboxed-api/sandboxed_api/../../myproject_build/sandboxed-api/sandboxed_api/proto_arg.pb.cc`.
Note the duplicated project build directory component in the
canonicalized version:
`/parent/myproject_build/myproject_build/sandboxed-api/sandboxed_api/proto_arg.pb.cc`.

This change simple omits the computation of any relative file paths and
simply uses `_pb_PROTOC_OUT_DIR` which defauls to
`CMAKE_CURRENT_BINARY_DIR`, which should always contain the correct
path.

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.
