Trace Redaction - Timeline and Build Timeline

The timeline data structure is critical to future operations. The
timeline is a query optimized structure that, given a pid and ts,
will traverse the thread hierarchy to find which package the
thread belongs to.

The thread-to-package relationship is not fixed. Thread id recycling
means that threads will wonder between packages. This means a thread
that didn't need to be redacted, could suddenly need to be redacted.
