Create repos on our infrastructure for TOPL related code

We should, now after merging and deploying Tor Onion Proxy Library code (see legacy/trac#27609 (moved) and child tickets), get the code onto into our tpo git infrastructure, I think, and create additional user repositories if needed.

So, having some tor-onion-proxy-library repo we use (and for which the github one could be the official upstream) and one for tor-android-service where we can tag and sign releases would be a good start. Not sure if there is more we should consider.

Then we can get changes to any of the new projects treated with our normal code review and commit push process.

We should think about who should have push access to those repos. I think sisbell, sysrqb, and I could be a decent start for that.
