Comment:

 I added a fixup to use the rend_service accessor.

 For the rest of it, we're a bit late in the game to decide that we want to
 have a new negotiation mechanism to disable one-ended padding.
 Furthermore, if the padding overhead starts crushing us even before all
 clients and relays have upgraded to use padding fully yet, we should just
 disable the entire netflow padding feature and figure out how to deal with
 that problem, rather than polluting the code with more complicated kill
 switches and negotiation methods based on guesses about what might cause
 problems, especially for issues that will only be a problem for a short
 period of time.
