libthr: Use kern.stacktop for thread stack calculation.
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.
