* [WIP] Add post build checks for catching and reporting bad builds + test projects.
* Move all type of issues into a single project. Tested all sanitizers.
* First version of the script for performing bad build checks. Still not ready to commit.\
* Added a valid example that should pass all the checks + fixed instrumentation check.
* Use SIGTERM and the handler calling _exit(0) for the startup crash case.
* Small fixes.
* Ignore startup_crash check_for fuzzing engines other than libFuzzer.
* Use "local" for local variables in the script, fix container name.
* Add COPY step for bad_build_check into base-runner Dockerfile.
* Make bad_build_check temporary noop unless EXPERIMENTAL_BAD_BUILD_CHECK is set to 1.
* Temporary remove test binaries step.
* Remove empty line.
* Remove unnecessary env variable.
Separate test_report script runs tests and generates junit-style
reports. The script doesn't fail when fuzzer fails, but marks it as
failed instead.
