The previous one was not quite correct in cases where the outside binary path
did not match the inside path. This should be fixed with this.

Caused failures if root is mounted as nodev, nosuid etc.
Root is pivoted and unmounted right after this anyhow.

This makes the class more ergonomic because
* You don't have to heap allocate the builder.
* You can create a policy builder "template" and re-use it across sandboxes to avoid repetitive work.

These where inadvertently introduced in an internal cleanup change.
This change also removes a C++17-ism in var_proto.h. To make things easier for
downstream projects, we should stick to C++11 for the time being.

This change removes the in-tree documentation in favor of the one hosted on
the Google's Developer site. This makes it easier to maintain for the
sandbox team, as there is now only a single source of truth for both internal
and external documentation.
If you find errors/bugs in the documentation, please file regular GitHub
issues.

This fixes some CMake-3.12+-isms, like `list(JOIN ...)` and setting link
properties on OBJECT libraries.

The temporary solution for binaries/tests that fully statically linked is to
link against `gflags` using `-Wl,--whole-archive`. This will no longer be
necessary, once Abseil ships with logging. Then we can (finally) use Abseil
flags and use a logging library that does not depend on a different flags
library.

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.
