dmatlack, pgonda, andrew.jones, Vishal Annapurve
Consolidate common startup logic in one place by implementing a single
setup function with __attribute((constructor)) for all selftests within
kvm_util.c.
This allows moving logic like:
/* Tell stdout not to buffer its content */
setbuf(stdout, NULL);
to a single file for all selftests.
This will also allow any required setup at entry in future to be done in
common main function.
More context is discussed at:
