* [cifuzz] Copy repo from image before checking out.
Do this instead of cloning repo anew.
Fixes: https://github.com/google/oss-fuzz/issues/6755
* fix tests
* Add test code for cifuzz-example
* fix
1. Move most of the generic stuff into BasePlatformConfig.
2. Make a GCB platform config that sets WORKSPACE and PROJECT_SRC_PATH so users don't have to.
3. Make a skeleton prow platform_config for Mitchel to fill out.
4. Make users explicitly specify the CFL_PLATFORM so we can pick CI environments
Fix diffing on non-GitHub and improve config
1. Remove obsolete comments.
2. Remove unused function get_pr_ref
3. Correct comment on git_sha
4. Rename commit_sha to git_sha
5. Make base_commit, pr_ref, and base_ref non-github specific and move to
CiEnvironment.
6. Hoist get_diff_base to base class to allow diffing
7. Fix downloading coverage on non-Github.
8. Add TODO so that we don't assume github actions is run on github.com
(enterprise users)
9. Rename repo_url to git_url.
10. Add missing git_url method base class.
11. Clarify what git_url, git_sha and pr_ref are for and leave TODOs about how
we can eliminate them.
12. Fix typos.
Handle upgrade to Ubuntu 20.04
1. Don't do any special handling for MSAN anymore. It isn't needed.
2. Don't do any special handling for msan-libs-builder it doesn't
exist anymore.

The current way adds a lot of ordering assumptions, and doesn't fit too
well with parallel batch fuzzing either. Add a "upload-build" boolean action
input that can be added to "build_fuzzers" to upload latest builds
instead.
Builds are now uploaded by commit hash, rather than a fixed "latest" name.
ClusterFuzzLite's download_latest_build will check the last 3 commits and download the
first available build by git hash.
Also rename code uses from `project_name` to `oss_fuzz_project_name`, to
be more explicit, and use it to determine whether or not we're running
an OSS-Fuzz project or not.
For external fuzzing #6051.
1. Make coverage script accept an env var that controls where the generated report is written to. Use this in generate_coverage_report.
2. Rename CoverageGetter to OSSFuzzCoverage
3. Make affected_fuzz_targets get coverage object from clusterfuzz_deployment.
4. Add stubbed FilesystemCoverage class that will be used by non-OSS-Fuzz users.
5. Make ClusterFuzzLite able to return coverage object by downloading old coverage report and returning a FilesystemCoverage object.
6. Add stub to ClusterFuzzLite for uploading coverage.

Also:
1. Support coverage builds.
2. Add an integration test for coverage builds and reports.
3. Refactor docker code so that there is less duplication in getting arguments for docker run, in particular when handling container (production) vs no container (testing).
4. Rename coverage.py to get_coverage_report.
5. Add tests for untested functions in docker.py
6. Add a test for get_fuzz_target_runner.
1. Moving the _create_config and create_config functions from build_fuzzers_test.py and run_fuzzers_test.py into test_helpers.py (which is now part of cifuzz instead of infra) and share code between them.
2. Rename artifacts_dir to crashes_dir in run_fuzzers.py. "artifacts" is ambiguous.
3. Make some small changes to pytest.ini to improve debugging.
Fix behavior of build_image --pull (Fixes#5640)
Also refactor helper.py:
1. Change behavior of functions so that most return True on success and False on failure.
2. Only main will return 1 on failure and 0 on success now. Previous behavior was very error prone.
3. Rename _get_output_dir to _get_out_dir.
4. Make function docstrings use descriptive tense.
5. Make helper.py print help when no argument is specified.
