Overhaul exception reporting.

unittest2 recently added the ability to show local variables in
tracebacks as https://github.com/testing-cabal/testtools/issues/111
requested for us. Reusing that requires some refactoring of our code,
in particular where we were reimplementing bits of the traceback
module. Now we can just hard-depend on traceback2 and linecache2 which
are brought in by unittest2 1.0.0.
