Also properly check status of send and use one-byte messages

6b24025860 CMake targets for SAPI, add find_package() support for libffi
This change adds CMake targets for the actual Sandboxed API library. On its
own, this is not very useful, as there is no CMake equivalent to the
sapi_library() rule, yet. This will be worked on next.

c7f7666d9d Do not leak macro definitions in stack-trace.h
Since we use glog, we need to still rely on gFlags for as long as Abseil
logging is not yet released. To do this, we have the util/flag.h header in
SAPI, faking the newer style API of Abseil's flags library.
The rationale behind this is that glog includes/builds with gflags for
command line flag parsing and having more than one flag parsing library
active at the same time is asking for trouble.

4e20e0702a Use full workspace name to access Bazel packages in generator
Since the interface generator is invoked via a Bazel macro, it will be
expanded in the embedding context of the project using SAPI, so package access
needs to go through the full workspace root @com_google_sandboxed_api.

This change also modifies the CMakeLists.txt accordingly, as the "external"
subdirectory is no longer needed/wanted.

0d16c136ae Make external usage easier by providing a sapi_deps() workspace rule
If using Sandboxed API from an external Bazel WORKSPACE, dependencies can be
imported by declaring the repository and calling `sapi_deps()`:

```python
git_repository(
    name = "com_google_sandboxed_api",
    commit = "master",
    remote = "https://github.com/google/sandboxed-api.git",
)

load(
    "@com_google_sandboxed_api//sandboxed_api/bazel:sapi_deps.bzl",
    "sapi_deps",
)

sapi_deps()
```

97b5f0767a Find libclang so that Python3 works, remove PY2 annotations
We now require that Debian users install the `python3` and `python3-pip`
packages. This change lets the Python code search for `libclang.so`, which can
be located in different directories, depending on version, and is not found by
default otherwise.

Fixes #28

24c3e34344 Implement a GetDataDependencyFilepath() for CMake (non-Bazel really).
This code assumes, like Bazel's runfiles that the data dependency to access
exists in the same sub-tree as the binary:

WORKSPACE
+- sandboxed_api/sandbox2/examples/crc4
                                   +- crc4bin
                                   +- crc4sandbox

The code requires the directory structure to exist, so that in the example
above, crc4sandbox can use
  GetDataDependencyFilepath("sandboxed_api/sandbox2/examples/crc4/crc4bin")

regardless of how it was called.
