sh: Proper show_stack/show_trace() implementation.
This splits out some of the previous show_stack() implementation which was mostly doing the show_trace() work without actually dumping any of the stack contents. This now gets split in to two sections, where we do the fetching of the stack pointer and subsequent stack dumping in show_stack(), while moving the call trace in to show_trace().
