This change adds support for using the `includes`, `include_prefix` and
`strip_include_prefix` attributes of the `cc_library()` rule. Without it,
the libtooling based header generator will not be able to find all
necessary includes as it is much stricter than the current libclang based
one in that regard.

This makes `sapi_library()` more compatible with Bazel's native `cc_library()`
rule.

This change introduces an experimental `generator_version` attribute to the
`sapi_library()` rule. Version `1` will select the current interface
generator, which is based on libclang and Python. Setting the attribute to
version `2`, will select the newer interface generator written in C++ that
uses a full clang compiler frontend for parsing. Both emit equivalent header
output, differences in parsing and/or edge cases notwithstanding.
The default, as of now, is still the old version `1` generator.
Note: CMake allows to select the new interface generator globally by setting
`SAPI_ENABLE_GENERATOR`.

This will allow us to experiment with (and subsequently migrate to)
changes to the generated API, possibly incompatible ones.
This change should be a no-op for current builds, as there is only
a single version of Sandboxed API.

This change merges the internal version of `sapi.bzl` with the external version again:
- Add more docstrings to the various macros
- Skip creation of `.isystem` file, get info from toolchain instead

Use [`direct_headers`](https://bazel.build/rules/lib/CompilationContext#direct_headers)
from the Bazel/Blaze compilation context instead of _all_ transitive headers.
For the clang based generator, this means we don't try to parse
`textual_headers`, which will fail (they are by definition not
stand-alone, after all).

The Bazel build already queries the current toolchain for its system include
directories. This change brings feature parity and is necessary for systems
with unusual include locations.

Build macros in earlier versions of Bazel (pre-1.0) needed to specify
targets in a different format, depending from where they were
included/expanded at build time.
For example, a `sapi_library()` macro invocation in one of the directories
under `examples`, always needed to depend on the SAPI main library as
`//sandboxed_api:sapi`. When using SAPI from another Bazel project, the
same macro would have needed to depend on
`@com_google_sandboxed_api//sandboxed_api:sapi`. The `sapi_library()`
macro was thus checking the repository name and conditionally changed
the dependencies. This approach is brittle and as of Bazel 3.1.0 no
longer works.
This CL simple removes the conditional prefix and unconditionally uses
`@com_google_sandboxed_api`.
Tested on Bazel 1.2.1, 2.2.0 and 3.1.0
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.

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.

Starting with Bazel 0.27.0 --incompatible_depset_is_not_iterable became the
default.
