Nick Mathewson a6627fdb80 Remove the legacy_test_helper and legacy_setup wrappers 
These wrappers went into place when the default type for our unit
test functions changed from "void fn(void)" to "void fn(void *arg)".

To generate this patch, I did the same hokey-pokey as before with
replacing all operators used as macro arguments, then I ran a
coccinelle script, then I ran perl script to fix up everything that
used legacy_test_helper, then I manually removed the
legacy_test_helper functions, then I ran a final perl script to put
the operators back how they were.
