92a8247777 Bazel: Add full support for virtual includes
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.

fc85310da2 bazel: Add copts, defines, and data to sapi_library()
This makes `sapi_library()` more compatible with Bazel's native `cc_library()`
rule.

4b2c730c5e Bazel: Make generator configurable
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`.

dc895f6dc8 Introduce an API version to the build rules
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.

466cc07254 bazel: Make generator configurable, minor improvements
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

60fcc5b63e Limit the number of includes fed into the header generator
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).

13c28403a6 Implement system include detection for CMake build
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.

6d97220e5c
Use common repository prefix everywhere
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

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.

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.
