Revert "Remove promotion to raw TCP based on heuristics"

This reverts commit fbaade429845546d751110caa0f886f7b1a62717 for the following reasons:

 - The commit only removed the proxy logic, while keeping the corresponding command line
   options etc. intact. That is quite confusing.
 - The switch is (and has been) off-by-default and the option help now clearly states
   that this needs to be used with caution. I'd argue that constrains the potential danger.
 - I have a specific use case that needs this, and implementing it as an addon is rather
   difficult at the moment.

That being said, this revert is a rather pragmatic temporary decision,
the functionality should clearly be made more explicit and protocol switching should
be moved to an addon.
