New description:

 This is the parent ticket for the pieces of work required to make it
 possible to use circuitpadding.c in a trace simulator outside of Tor, so
 that defenses could be re-applied to crawl traces quickly without needing
 to re-crawl a set of sites.

 An alternate way to do this, instead of extracting this code, is to make
 use of our unit testing framework and build the tracer as a unit test. We
 have mechanisms to mock the networking functions so that they output new
 traces, and then we can use the unit-test style to read in a trace file
 and output a new one, instead of performing a test.
