This change starts with Jsonnet as the canonical, ready-made sandboxed library
example. Follow-up changes should similarly migrate the OSS Internship
sandboxes.
- Add an `add_sapi_subdirectory()` which sets up source and binary directories
correctly when consuming SAPI as sub-project
- Restructure the Jsonnet `CMakeLists.txt` and simplify header inclusions
- Update the Jsonnet README file

This never worked properly worked anyways.
The root of the problem is likely ninja issue [#1330](https://github.com/ninja-build/ninja/issues/1330)

This partially reverts the zlib change in 41e0ca0. Turns out the
`CMakeLists.txt` that ships with zlib leaves much to be desired.

- Integrate `JsonnetTestHelper` into `JsonnetTest` class, remov multiple
inheritance
- Do not copy strings where it can be avoided
- Add missing includes to header files
This updates the mininum required version of CMake to 3.13, which is
present in Debian Buster.
At the same time, move all of our dependency handling to use
`FetchContent_Declare()`, `FetchContent_Populate()` and
`FetchContent_MakeAvailable()`. Since the latter was ony introduced in
3.14, provide a simple "polyfill" implementation for that.
As an added benefit, the configure step for libffi and libunwind will
now not be re-run every time the `CMakeLists.txt` changes.
Other changes:
- Explicitly spell out that we're testing up to 3.22 in
`cmake_minimum_version()`
- Rename `check_target()` to `sapi_check_target()` to avoid conflicts
with Abseil.
This fixes some build issues due to changes in Sandboxed API and
upstream Jsonnet.

Plain `readdir` is preferred and while not (yet) specified in POSIX it is thread-safe for different directory streams in popular implementations.

- Check for Linux (Android TBD once that lands) and C++17
- Move `SAPI_HARDENED_SOURCE` check after compile options are evaluated
- Use a more modern way to set the required C++ standard, compatible with
Abseil's `ABSL_PROPAGATE_CXX_STD`.
- Scope `-fno-exceptions` and `POSITION_INDEPENDENT_CODE` to SAPI targets
- Increase maximum stack frame size yet again

Newer versions of libunwind use `PTRACE_GETREGSET` to obtain register data.
This change should make it easier to upgrade the libunwind dependency.

The former fixes the actual compiler option checks in `CMakeLists.txt`.
The latter is to avoid a compiler warning in `sandboxed_api/sandbox2/util.cc`,
which needs a stack frame size bigger than pthread's default value (16K).

Raw `SAPI_RAW_PCHECK` may dump core, depending on environment settings
(issue #89).
This is undesirable in the face of invalid command-line arguments.

The newer version includes a fix for a compilation error on newer
systems (specfically, `benchmark_register.h` was missing an include
for the `limits` header).

This fixes a build warning about an uninitialized variable whiche turns into
an error in recent Clang versions.
