6a58a29039 Make CMake superbuild behave more similar to FetchContent
- Move CMake superbuild files
- Drop use of `CMakeLists.txt.in` configure files
- Allow overriding dependency directories. For now, this should only be
  used by GitHub workflows. Will be expanded on later, possibly renaming
  the variables.

This change is one in a series to make it easier to consume/customize
Sandboxed API in downstream projects.

Drive-by:
- Update `.gitignore` to ignore clangd's `.cache` directory

55a8373ec3 Avoid sanitizer macros use Abseil's where necessary
Using C++17 means we can get rid of many `#ifdef`s by using `if constexpr`.
This way, we ensure that both branches compile and still retain zero runtime
overhead.

Note that open source builds of Sandboxed API do not ship with sanitizer
configurations yet. This will be added in follow-up changes.

3a95d9df41 Fix cURL example
Due to a naming mixup in `oss-internship-2020/curl/CMakeLists.txt`, the
necessary `WriteToMemory()` callback was not linked into the sandboxee,
leading to a segfault in the sandboxee when trying to run the
tests/examples.

As another issue, cURL seems to call `sysinfo` and `rt_sigaction` in
recent versions and with recent libc.

Drive-by changes:
- Use the SAPI status macros instead of manually checking `absl::Status`
- Put tests in namespace
- Some Google C++-style fixes
- Start the mock test server only once per test suite

Fixes #72 for cURL.

dbaf95c724 Move utility code into sandboxed_api/util
This change should make it less confusing where utility code comes from.
Having it in two places made sense when we were debating whether to publish
Sandbox2 separately, but not any longer.

Follow-up changes will move `sandbox2/util.h` and rename the remaining
`sandbox2/util` folder.
