Tor: Split into seperate applications

It is safe from an anonymity perspective to run separate instances for relaying and onion services as seen in Tor logs. Split them into two separate applications. Further, split out the proxying also. Three applications will be:

• Tor Proxy
• Tor Relay
• Tor Onion Service

Using Tor for package download will go into Tor Proxy application. Using upstream bridges will be present in all three applications.
