back2source: Run d2d analysis on many projects

[pombredanne]

For each of the ecosystems below, we should define a set of interesting projects then analyze, and then review results for accuracy

The high level steps are:

• Collect a list of PURLs and download URL pairs
• Run the d2d scans
• Collect and review issues and accuracy
• Fix bugs and run again
• Eventually find issues build a report of these and reach out to projects for key issues

The ecosystems to consider are:

• back2source: Run pipeline for 100 Windows C++ projects #1470
• back2source: Run pipeline for 100 macOS projects #1471
• back2source: Run pipeline for 100 .Net projects #1472
• back2source: Run pipeline for Java and native code and Android apk and dex classes #1473
• back2source: Run pipeline for Python and C/C++ source and the python bytecode and native binaries #1474
• back2source: Run pipeline for Rust source and binaries #1475
• back2source: Run pipeline for Ruby source and gem packages #1476
• back2source: Run pipeline for JavaScript #1477
