- Ubuntu 18.04 ships with GCC 7, which needs `std::move()` when returning an `absl::StatusOr<>`
- Ignore C++ AST nodes of type `cindex.TypeKind.UNEXPOSED` in Python generator
- Remove default values in `ubuntu-cmake.yml`

This allows resource-constrained environments to benefit from the
space savings of dynamic linking. This is not meant to be used in
the general case.

FS checks are an internal feature that has been deprecated for a while in
favor of user namespaces.

The defined raw logging macros should be compatible with Abseil and
we can remove our version once Abseil releases theirs.

- Bazel: Use "incompatible" flag to fix fully static linking. The flag will
become the default in Bazel 4.0.
- Bazel: Deduplicate features into `FULLY_STATIC_FEATURES` variable
- CMake: Remove the testcase properties. `sapi::base` already sets
`POSITION_INDEPENDENT_CODE`. Note that `-pie` is incompatible with `-static`
and `-static-pie` requires GCC 8 and GLIBC 2.27.

The default policy causes immediate termination of a sandboxee that
calls `bpf`(2).
This does not allow for try-call use of `bpf()` to test for optional
features.
To support such try-call use cases, sandboxes would like to say:
```
sandbox2::PolicyBuilder builder;
builder.BlockSyscallWithErrno(__NR_bpf, EPERM);
```
but this doesn't work because the default policy unconditionally treats
`bpf()` as a sandbox violation.
Remove the bpf violation check from the policy if `bpf()` is explicitly
blocked with an errno.

The semantics of the example remain unchanged. This change is in preparation
for the new Clang based header generator, which will parse most files in C++
mode. `ptrace`'s first argument cannot me implicitly converted from `int` in
C++.

Updates syscall arguments mostly according to this list and more recent kernel sources:
https://chromium.googlesource.com/chromiumos/docs/+/master/constants/syscalls.md#x86_64-64_bit
The list includes some more syscalls that were recently added.
Follow-up changes will do the same for x86-32, POWER and AArch64.

If the sandboxer calls `IPC::EnableLogServer()` (and modifies the sandbox policy
accordingly), sandbox logs will be sent back to the sandboxer.

This change allows us to emit forward declarations to classes that are
templated. For headers generated by the proto compiler this is sometimes
necessary.
Note:
- This will only emit types for a single level of template instantiations.
That is, template template arguments are not supported.
- Typedefs only occurring in template arguments will be fully desugared
and thus will not be available under their aliased name in the generated
API code. This is consistent with the Python based generator (which
does not emit these at all and relies on text extraction).

This change includes a small refactoring to remember which types the generator
has already seen during header generations. Otherwise we may loop indefinitely
on certain complex types. One such type is `std::FILE` in Clang's libc++.

We need to add the `oss-internship-2020` and `examples/hello_sapi`
directories to `.bazelignore`, so that `bazel build ...` works on a clean
working copy. This is because the Bazel builds in these directories use their
own `WORKSPACE.bazel` and this does not nest well, leading to all kinds of
hard to debug errors.
