We need a tapset that uses the new task-finder runtime in order to populate and
maintain systemtap script-level globals/functions that allow pid-based data lookup.

Specifically:

function pid2execname:string (pid:long) {}
function pid2cwdpath:string (pid:long) {}
... and maybe more.

These functions could be implemented as embedded-c or script, using globals
that are managed by utrace task-finder callback functions notifying the tapset
of tasks running chdir()/chroot()/exec().  To initially populate the globals
(for preexisting processes), the embedded-c code would need to use possibly
sleepy kernel functions to process task_struct*'s.
