8a7d0d1cb3 Use a nested userns&mntns to pre-pivot_root 
This addresses a latency issue - chroot_fs_refs called inside pivot_root
in the kernel can take several milliseconds on machines with many threads
running.
This might not always reduce latency for custom forkservers, as additional
fork can be more costly than pivot_root.

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.

c6b8e301e4 This fixes broken _proto_cc_cc_proto build target suffixes. 
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.

ea1a934d51 Migrate Sandboxed API docs to developer.google.com/sandboxed-api 
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.

b7cbc36071 Follow-up to 3c51348 fixing linker issues with gflags and glog 
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.

3c51348aaf Enable CMake projects to consume Sandboxed API via add_subdirectory() 
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.

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.

This code assumes, like Bazel's runfiles that the data dependency to access

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.
