Sanitize dumped stacks to remove data that may be identifiable.
In order to sanitize the stack contents we erase any pointer-aligned
word that could not be interpreted as a pointer into one of the
processes' memory mappings, or a small integer (+/-4096).
This still retains enough information to unwind stack frames, and also
to recover some register values.
