This change moves away from a classical superbuild which downloads and builds
at build time. Instead, we now follow a "Fetch Content" workflow (available as
FetchContent in CMake 3.11+) and download dependencies at config time.
Rationale: Superbuild projects have the disadvantage that projects cannot
directly access their individual declared targets. This is not a problem with
regular libraries, as those are usually/supposed to be installed. With
Sandboxed API, this is not desirable, as it has dependencies like Abseil and
glog, which are almost always consumed by including their source tree using
add_subdirectory().
Fixes#10 and makes external embedding easier.

Also properly check status of send and use one-byte messages
to avoid issues with partial send, receive.

* Implement add_sapi_library() similar to the Bazel rule
* Fix SuperBuild so that glog properly depends on gflags (needed for --logtostderr)
* Raise minimum required version of CMake to 3.10 (Ubuntu 18.04 LTS)
* Update sum sandbox policy to allow to get IDs and PIDs

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.

When fetching exit status only lower 8-bits will be read.
Thus if getpid()&0xff == 0 the test can fail.

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.

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.

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()
```

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.

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.
