I've got v2 WIP that minimizes the delays, cleans up build flags, and
adds a basic shadow variable test.

Since these tests are based on top of Petr's current patchsets for
atomic replace and shadow variables, it probably makes sense for those
to merge first.  I can post test results to his patchsets if that helps.

These tests are basically a mash up of some of the tedious callback
Documentation and shadow variable sample livepatches.  Since there will
be a lot of duplication, should we just remove redundant doc/samples in
favor of these tests?
