ce477da8a7 Ignore regular cells in padding circuits. 
Padding circuits were regular cells that got closed before their padding
machine could finish. This means that they can still receive regular cells from
their past life, but they have no way or reason to answer them anymore. Hence
let's ignore them before they even get to the proper subsystems.

_some_ of the data, and it makes sure that the outputs are as expected.

a79e2c2975 practracker: better warning/regen handling 
Now that there is only one toplevel place where we print problems,
we can redirect just that one print to a file when we are
regenerating the exceptions.txt file.  Previously we redirected
sys.stdout, which is naughty, and forced us to send warnings (and
warnings alone) to stderr.

f306d12b58 Refactor handling of TestingTorNetwork 
Previously, when TestingTorNetwork was set, we would manually adjust
the initvalue members of a bunch of other config_var_t, and then
re-run the early parts or parsing the options.

Now we treat the initvalue fields as immutable, but instead assign
to them in options_init(), as early as possible.  Rather than
re-running the early parts of options, we just re-call the
options_init_from_string() function.

This patch de-kludges some of our code pretty handily.  I think it
could later handle authorities and fallbacks, but for now I think we
should leave those alone.

6303c9aa26 Practracker: add tolerances for exceptions 
When an exception is present, we can now violate the limit by a little
bit and only produce a warning.  The strict flag overrides this
behavior.

I've given file sizes a 2% tolerances and function sizes/include
counts a 10% tolerance.
