Protobuf 3.5 would require a Bazel flag
bazel build --incompatible_package_name_is_a_function=false
for Bazel 0.21 because its bazel syntax is old.
Rather than building with this flag, let's just update
the protobuf version.
Also, fix lint.
- `--force_pic` speeds up the build ~1.5x on my machine.
- Marking internal_client_server_test as flaky avoids misleading
failures in some environments.
- Updating rules_boost avoids spamming stdout with configure script
messages.
These were in some, but not all, of the existing BUILD files. They make
it easier to vendor cartographer, as Bazel complains if a BUILD file in
//third_party is missing a licenses() declaration.
This doesn't work when cartographer is an external workspace, due to a
limitation in cc_grpc_library. However, the //cartographer target will
still work it is external, and cartographer_grpc users can vendor the
repository.
This does not include cartographer_grpc, nor any of the binaries
(*_main.cc). It has been tested with Bazel 0.9.0 on Ubuntu 14.04 with
the latest (at time of writing) dazel/dazel container, by running:
```
bazel build //...
bazel test //...
```
While this is a large CL, the files under third_party are not new - they have been through internal review, and this is their open-source release. The other files come to 212 lines of code.
