    [SPARK-10359] Enumerate dependencies in a file and diff against it for new pull requests
    
    This patch adds a new build check which enumerates Spark's resolved runtime classpath and saves it to a file, then diffs against that file to detect whether pull requests have introduced dependency changes. The aim of this check is to make it simpler to reason about whether pull request which modify the build have introduced new dependencies or changed transitive dependencies in a way that affects the final classpath.
    
    This supplants the checks added in SPARK-4123 / #5093, which are currently disabled due to bugs.
    
    This patch is based on pwendell's work in #8531.
    
    Closes #8531.

    [SPARK-10359][PROJECT-INFRA] Multiple fixes to dev/test-dependencies.sh script
    
    This patch includes multiple fixes for the `dev/test-dependencies.sh` script (which was introduced in #10461):
    
    - Use `build/mvn --force` instead of `mvn` in one additional place.
    - Explicitly set a zero exit code on success.
    - Set `LC_ALL=C` to make `sort` results agree across machines (see https://stackoverflow.com/questions/28881/).
    - Set `should_run_build_tests=True` for `build` module (this somehow got lost).

    Closes #10543 from JoshRosen/dep-script-fixes.

    [SPARK-10359][PROJECT-INFRA] Use more random number in dev/test-dependencies.sh; fix version switching
    
    This patch aims to fix another potential source of flakiness in the `dev/test-dependencies.sh` script.
    
    pwendell's original patch and my version used `$(date +%s | tail -c6)` to generate a suffix to use when installing temporary Spark versions into the local Maven cache, but this value only changes once per second and thus is highly collision-prone when concurrent builds launch on AMPLab Jenkins. In order to reduce the potential for conflicts, this patch updates the script to call Python's random number generator instead.
    
    I also fixed a bug in how we captured the original project version; the bug was causing the exit handler code to fail.
    
    Author: Josh Rosen <joshrosen@databricks.com>
    
    Closes #10558 from JoshRosen/build-dep-tests-round-3.
