  - Use SpotBugs 3.1.2, and NP_NONNULL_PARAM_VIOLATION

    This patch upgrades the SpotBugs plugin to 3.1.3 and the engine to
    3.1.2. The changelog is
    https://github.com/spotbugs/spotbugs/blob/3.1.2/CHANGELOG.md

    SpotBugs 3.1.2 supports the nullable annotations in Checker Framework
    (see
    https://github.com/spotbugs/spotbugs/commit/dd436ff56abf0273a080ad228fcf5abd8ee3a097
    for the patch), so we can re-enable NP_NONNULL_PARAM_VIOLATION when
    using SpotBugs. This involves using a separate configuration, so this
    patch splits everything out, including the report directory for
    projects which run both FindBugs and SpotBugs.
