            Bug ID: 221323
           Summary: memset_s() and abort_handler_s() missed some standard
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin

patch to correct the mentioned issues, updating the memset_s test case as well

abort_handler_s() currently simply calls abort(), though the documentation says
it needs to do more work - "Writes an implementation-defined message to stderr
which must include the string pointed to by msg and calls abort()."

memset_s() is missing the fact that it should treat "n > smax" condition as
error, and invoke the constraint handler after filling the buffer - "following
errors are detected at runtime and call the currently installed constraint
handler function after storing ch in every location of the destination range
[dest, dest+destsz) if dest and destsz are themselves valid", one of the errors
is "n > smax" itself.
