commit 865c48f78c7f0a87448ffcb2b384389188a18a74

Add the pstrace function to tapset with documentation and example test
The pstrace function generates a string that traces the processes from
the task_struct passed in back to the ancestor spawned by init(1).
This allows you to determine what processes are ancestors for a particular
process.
