overlay: parse tracepoints from sysfs to figure out fields' location
With changes going to drm-tip, the tracepoints field locations are
going to change. This change introduces a tracepoint parser (using a
peg parser) which lets us figure out field positions on the fly.
v2: Fix automake build (Lionel)
v3: Make overlay build conditional on peg (Petri)
Make wait_end callback more readable (Chris)
Drop tracepoint_id(), instead parsing from format file (Lionel)
v4: Fix existing configure.ac issue with overlay build (Petri)
v5: Silence unused function (Lionel)
v6: Fix missing double quote in v4 (Lionel)
