1.3	10-Aug-2023	mrg	avoid various use-after-free issues. create a ptrdiff_t offset between the start of an allocation region and some interesting pointer, so it can be adjusted with this offset after realloc() returns. for pdisk(), realloc() is a locally inlind malloc() and free() pair. for mail(1), this required a little bit more effort as the old pointer was passed into another file for fix-ups there, and that code needed to be adjusted for offset vs old pointer usage. found by GCC 12.
