Change probe's format_pointer_ routine to use interpret_ptr_ (MCR10035)

[Gary Dixon <gary.c.dixon@…>]

probe subroutines already use interpret_ptr_ in specific situations to display more meaningful information about pointers. See probe_print_handlers_.pl1 and probe_display_data_.pl1 for such existing uses.

However, the general pointer display routine, format_pointer_.pl1 does not make use of interpret_ptr_ to provide a more meaningful description of displayed pointer values. format_pointer_ is also called by display_data_, which is used by analyze_multics and dump_segment commands. Thus, improved pointer descriptions from format_pointer_ could enhance many tools.

Currently, the most neglected case is mapping a pointer into a bound segment to its segname$entryname symbolic form. Such mapping of numbers to named entrypoints can greatly assist in debug and investigation efforts.
