df1c31188d Fix sums test under MSAN by allowing Scudo to add MAP_NORESERVE in mmap()
Note: This change allows `MAP_NORESERVE` generally, not just for MSAN. This follows
what we do for `AllowTcMalloc()/AllowSystemMalloc()`

221e929018 Include shell-based tests in OSS builds
These were previously dependent on an internal-only testing target.

For now, this only works with Bazel, but should enable us to have better test coverage in GitHub actions.
Eventually, all of these shell-based tests should be converted to `cc_test`s.

fd20eb0b4d Reorder error logging before Terminate()
Calling `Terminate()` issues additional syscalls that may clobber the `errno`
value. Reordering the log statements ensures we actually log the initial error
in `read()`/`write()`.

bb6ae1d4ab Introduce AllowRestartableSequencesWithProcFiles() and tidy up.
1. In many cases, sandboxes need to allow /proc/stat and /proc/cpuinfo so that
get_nprocs(3) will work; otherwise, per-CPU logic can't determine how many CPUs
there are. Unfortunately, some of those sandboxes also disable namespaces. The
solution is to provide two functions: AllowRestartableSequencesWithProcFiles(),
which allows syscalls and files; and AllowRestartableSequences(), which allows
syscalls only. Sandboxes should usually call the former; sandboxes that disable
namespaces should instead call the latter and are responsible for allowing the
files via the deprecated Fs mechanism.

2. Make the mmap(2) policy evaluate prot AND flags, not prot OR flags.

3. Order the code and the comments identically for better readability.

5267d14248 Take a vector in Policy::AllowUnsafeKeepCapabilities()
The existing function signature took a `unique_ptr<>` owning a vector, and
took `nullptr` to mean an empty set of capabilities. This is more naturally
modeled by taking the vector directly and `std::move`-ing it.

ca6ec4337d Add workaround for active Tomoyo LSM
Recenly, Debian based distribution kernels started activating the Tomoyo Linux
Security Module by default. Even if it is not used, this changes the behavior
of `/dev/fd` (pointing to `/proc/self/fd` by default), which Sandbox2 needs during
`execveat()`.

As a result, Sandbox2 and Sandboxed API always fail without one of the following
conditions
- `/proc` mounted within the sandboxee
- `/dev` mounted
- `/dev/fd` symlinked to `/proc/self/fd` in the sandboxee's mount namespace

Some code pointers to upstream Linux 5.12.2:
- https://elixir.bootlin.com/linux/v5.12.2/source/fs/exec.c#L1775
- https://elixir.bootlin.com/linux/v5.12.2/source/security/tomoyo/tomoyo.c#L107
- https://elixir.bootlin.com/linux/v5.12.2/source/security/tomoyo/domain.c#L729

To find out whether your system has Tomoyo enabled, use this command, similar to
what this change does in code:

```
$ cat /sys/kernel/security/lsm | grep tomoyo && echo "Tomoyo active"
capability,yama,apparmor,tomoyo
Tomoyo active
```

The config setting `CONFIG_DEFAULT_SECURITY` controls which LSMs are built into
the kernel by default.

55a8373ec3 Avoid sanitizer macros use Abseil's where necessary
Using C++17 means we can get rid of many `#ifdef`s by using `if constexpr`.
This way, we ensure that both branches compile and still retain zero runtime
overhead.

Note that open source builds of Sandboxed API do not ship with sanitizer
configurations yet. This will be added in follow-up changes.

dbaf95c724 Move utility code into sandboxed_api/util
This change should make it less confusing where utility code comes from.
Having it in two places made sense when we were debating whether to publish
Sandbox2 separately, but not any longer.

`sandbox2/util` folder.
