            Bug ID: 221323
           Summary: memset_s() and abort_handler_s() missed some standard

patch to correct the mentioned issues, updating the memset_s test case as w=
ell

abort_handler_s() currently simply calls abort(), though the documentation =
says
it needs to do more work - "Writes an implementation-defined message to std=
err
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 - "follow=
ing
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 er=
rors
is "n > smax" itself.
