We need a way to show the individual counters, but this is a good first
start. To do the combined counters, we need to come up with something that
allows expanding of rows and what not.
As we gain in usage, we need to be more careful about using a prefix
that will not collide with other symbols. So version 3 of our ABI will
change to using Sysprof/SYSPROF/sysprof as the various prefixes.
The soname/api version bump will happen later on this branch so that
things are easier to test up until then.
