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.

Addresses #104 and also fixes a TODO to use `target_link_options()`
and the `LINKER:` prefix in the SAPI build defs.

Add a new option `SAPI_ENABLE_CONTRIB_TESTS` that builds the sandboxes
in `contrib/` if set.
The new `contrib/CMakeLists.txt` should be extended each time we add a
new sandbox to `contrib/`.
This is in preparation of a follow-up change that should test the
sandboxes using GitHub Actions.
Drive-by:
- Rename the tests in `jsonnet_tests.cc` to conform to the style guide.

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
