• Rewrite dedupe code from scratch, probably fixing all dedupe bugs
• extfilter: add substring match filter for file paths
• Add -u/--printunique option to print all non-duplicates (unmatched files)
• Dedupe-blacklisted kernel version check now happens before work is done
• Build warnings fixed; report any you get (except ENABLE_DEDUPE=1 #warning)
• New build targets static and static_stripped (for static binary builds)
