This change is a first step to make the SAPI variable hierarchy more sensible.
It turns the `Reg<T>` class into a descendant of `Pointable`, but without
making its `PtrXXX()` methods public (hence the `using` statements). Further
changes are needed to restructure this.
There are no functional changes and the class sizes, including vtables, should
not change.

Different versions of the `elf.h` header define their own integer types. For
example, even on LP64 systems, a 64-bit ELF integer types may decay into
`unsigned long long` instead of `unsigned long`.
This change replaces the various overloads with a single function template
that is well-defined for all integral types.

This is mainly so that the structure of the examples follows what we do
internally (not having separate directories).

This is the first change in a series that will eventually remove Sandboxed
API's use of multiple inheritance.
Drive-by:
- Rename short member names to full words
- Some reformatting

Note: This change allows `MAP_NORESERVE` generally, not just for MSAN. This follows
what we do for `AllowTcMalloc()/AllowSystemMalloc()`

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.

For OSS, this change should be mostly a no-op. Visible edits are due to
changed order of code and/or includes.

This mainly a debugging facility.
It makes diagnosing problems where sandboxed process just randomly exits whereas unsandboxed one runs to completion due to differences in the setup/environment much easier.

Also really own `exec_fd_` as previously if the executor is destructed without calling `StartSubProcess` the file descriptor would leak.

This was missing a friend declaration in order to actually compile.
It's now being used in the "stringop" example, so we test it as well.
Drive-by:
- Do not copy the proto's bytes the constructor, but use `std::move`

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()`.
