Use the new kern.stacktop sysctl to retrieve the address of stack top instead of kern.usrstack. kern.usrstack does not have any knowledge of the stack gap, so this can cause problems with thread stacks. Using kern.stacktop sysctl should fix most of those problems. kern.usrstack is used as a fallback when kern.stacktop cannot be read. Rename usrstack variables to stacktop to reflect this change. Fixes problems with firefox and thunderbird not starting with stack gap enabled.
