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.

Fixes some template issues that could lead to code not compiling when it
otherwise should.

The underlying issue is with a Copybara transform and the internal Blaze BUILD file.

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

When embedding SAPI in an external CMake project, the version of
`protobuf_generate_cpp` that we lifted from upstream protobuf produces
the wrong generated file paths.
For example, given this project structure:
```
/parent/
+-- myproject/
+-- myproject_build/ <- CMake build directory
+-- sandboxed-api/ <- Checkout from GitHub
```
And a CMake file in `myproject/CMakeLists.txt` that embeds SAPI like
this:
```
cmake_minimum_required(VERSION 3.12)
project(SandboxedTest LANGUAGES CXX)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
add_subdirectory(
${PROJECT_SOURCE_DIR}/../sandboxed-api
${PROJECT_BINARY_DIR}/sandboxed-api
)
```
Then `protobuf_generate_cpp` correctly invokes the protoc compiler to
generate
`/parent/myproject_build/sandboxed-api/sandboxed_api/proto_arg.proto.pb.cc'.
However, the path of the generated source file that is passed to the C++
compiler will be
`/parent/myproject_build/sandboxed-api/sandboxed_api/../../myproject_build/sandboxed-api/sandboxed_api/proto_arg.pb.cc`.
Note the duplicated project build directory component in the
canonicalized version:
`/parent/myproject_build/myproject_build/sandboxed-api/sandboxed_api/proto_arg.pb.cc`.
This change simple omits the computation of any relative file paths and
simply uses `_pb_PROTOC_OUT_DIR` which defauls to
`CMAKE_CURRENT_BINARY_DIR`, which should always contain the correct
path.

Add the location of the Python 3 interpreter to the CMake cache so
that its available in the `add_sapi_library()` macro in downstream
embedding projects.

Currently we extract all functions from the compilation unit - it doesn't really make sense as it will try to process functions in included files too.
As we require sapi_in flag, we have information which files are of interest.
This change stores the top path in _TranslationUnit and uses it when looking for function definitions to filter only functions from the path we provided.

The next release contains one major change: for function parameter annotations,
pytype will no longer treat (x: X = None) as equivalent to
(x: Optional[X] = None). This pytype behavior was based on an outdated version
of the type-checking spec. Annotations that were relying on the behavior now
need to explicitly declare themselves as Optional.
