* Add C++ build testing with clang and gcc
This adds Dockerfiles which test building flatc and the C++ library against clang
and gcc. See discussion at #5119. It is derived from the Travis CI tooling.
The GRPC tests are failing due to #5099 so those are commented out.
These are run from the .travis.yml file rather than the tests/docker/languages
folder because the builds may each take longer than 30 minutes and were hitting
Travis timeouts.
Parallel builds and build caching attempt to keep the build times low.
* Add GCC 8.3 and Clang 7.0 with sanitizers into CI (based on #5130)
- Add a docker based on Debian Buster.
- Add C++ building scripts for the docker.
- Leak-sanitizer requires SYS_PTRACE.
This runs a script in TravisCI that executes a bunch of small Docker image
scripts to test the language ports in isolated environments. This allows us to
test multiple language versions with little additional complexity.
