Shared test library functions lack a simple way to ensure proper cleanup in the event of a failure. The `log_onexit` cleanup pattern cannot be used in library functions because it uses one global variable to store the cleanup command. An example of where this is a serious issue is when a tunable that artifically stalls kernel progress gets activated and then some check fails. Unless the caller knows about the tunable and sets it back, the system will be left in a bad state. To solve this problem, turn the global cleanup variable into a stack. Provide push and pop functions to add additional cleanup steps and remove them after it is safe again. The first use of this new functionality is in attempt_during_removal, which sets REMOVAL_SUSPEND_PROGRESS.
