Change Details

- Rename from the teardown callback from 'zeroize' to 'cleanup' since this no longer zeroes keys. - Change the callback return type to void. Nothing checked the return value and it was always zero. - Don't have esp call into ah since it no longer needs to depend on this to clear the auth key. Instead, both are now private and self-contained. - Don't bother clearing pointers to NULL right before freeing the containing structure.
