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.

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.
When using SAPI from an external project via CMake, the small zlib patch
cannot be found during the config phase.
This change also fixes an oversight in that the tests depend on some of
the example code.
Regardless embedding code should set `SAPI_ENABLE_EXAMPLES` to `OFF`.
Disabling tests by setting `SAPI_ENABLE_TESTS` to `OFF` stays optional.

Build macros in earlier versions of Bazel (pre-1.0) needed to specify
targets in a different format, depending from where they were
included/expanded at build time.
For example, a `sapi_library()` macro invocation in one of the directories
under `examples`, always needed to depend on the SAPI main library as
`//sandboxed_api:sapi`. When using SAPI from another Bazel project, the
same macro would have needed to depend on
`@com_google_sandboxed_api//sandboxed_api:sapi`. The `sapi_library()`
macro was thus checking the repository name and conditionally changed
the dependencies. This approach is brittle and as of Bazel 3.1.0 no
longer works.
This CL simple removes the conditional prefix and unconditionally uses
`@com_google_sandboxed_api`.
Tested on Bazel 1.2.1, 2.2.0 and 3.1.0
Similar to what the Bazel build does, this change adds zlib as an additional
dependency when `SAPI_ENABLE_EXAMPLES` is set to `ON`.

BoringSSL (which is the crypto library used by most Google products) is starting to use madvise(_, _, MADV_WIPEONFORK) to protect random-number state from being duplicated by fork(). This causes extra madvise calls that sandboxes need to permit in order to continue functioning.

Abseil insists on having a Google Test directory, even if we're not going to
run (or even build) the tests.
This changes forces all test settings to `OFF` just for Abseil, allowing
SAPI builds to complete normally. Embedding projects should not be affected,
if they already included Abseil.

Note: This intentionally omits perfect-forwarding value assignments. This
avoids overly complex template expressions. The regular assignments are still
efficient.
