- Use default initialization
- Rely on `static_assert()` and use `if constexpr` when checking SAPI
variable type
- Small style fixes

- Drop `delim` argument from the `GetStackTrace()` family of functions.
We only ever used plain spaces.
- Use an `std::vector<std::string>` for the symbolized stack frames and
adjust the unwind proto accordingly.
This change now prints each stack frame on its own line while skipping
duplicate ones:

This way, one can just run `ctest .` in the build directory and it will only
run Sandboxed API and Sandbox2 tests.

Initializing `absl::Span`s like by assigning them from a temporary
array leaves them pointing to invalid data. Due to the way the linker
initializes these constant tables, _most_ of them will still be valid
_most_ of the time, leading to crashes when running sandboxees with the
`--sandbox2_danger_danger_permit_all_and_log` option.

Bazel 3.x now requires specifying `commit`, `tag` or `branch` in its
`git_repository` rule.

Otherwise ExecuteProcess is implicitly `[[noreturn]]` and this
might cause policy violations in `__asan_handle_no_return`
for ASAN builds.

This is done by simply building libffi in-tree. Normally, this is not
desirable, but in our case is actually ok, as this is an external
dependency to be pulled in and cleaning the source tree is easy in this
case.

Support LLVM >= 7.0.1 in Clang based header generator
This change glosses over small API changes introduced since LLVM/Clang
7.0.1, which ships with Debian Stable "Buster". Ubuntu 18.04 LTS "Bionic"
also shipped this (and subsequently updated to version 9).
Hence, compiling the generator should now work on all reasonable Debian
based distributions.

The "hello_sapi" example lives in a different WORKSPACE as it is intended to
show how to embed SAPI in your own projects. However, this is not compatible
with simply running `bazel build //sandboxed_api/...` after checkout.
This change simply replace `copts = ["-I."]` with `includes = ["."]`, so that
generated headers can be found reliably, regardless of how the example is
compiled.

- Extract dependent types directly from the Clang AST and re-serialize
back into compilable code
- Collect types and emit diagnostics
- Format generated code

This change contains a "hello world"-style example library to be
sandboxed. It consists of a stand-alone CMake and Bazel project that
uses Sandboxed API as its dependency.
To use Sandboxed API in an external project, it should be enough to
copy the files in the `sandboxed_api/examples/hello_sapi` directory
as a starting point.
