Implement efficient binary package updates by patching prior releases instead of downloading large packages afresh - please see: (jkoshy.net) Efficient Package Distribution

Primary milestones:

• Define the patching protocol between the package manager client (i.e., pkgin) and the Patch server.
• Implement the 'Patch Server', defaulting to current behavior when binary patches are missing.
• Add patch protocol support to the pkgin package management client.
• On the 'Patch Server', implement a pipeline to generate binary patches whenever new package releases are added to it.

Nice to have:

• Add file-format-specific (i.e., ELF-, JPEG-, PNG- specific) binary patch generation.
