The limitations of current approach for Gallium trace diffing via
'tracediff.sh' are becoming all too apparent, as we are first dumping
both trace to text and performing plain line-based sdiff on them.
This obviously loses the context of calls and sometimes results in
confusing diffs when subsequent calls are similar enough. It also
prevents us from formatting the diff output in ways that would
benefit readability.
In attempt to rectify the situation, reimplement the diffing completely
in Python, using difflib and adding the necessary plumbing into the trace
model objects etc.
