Add _FORTIFY_SOURCE implementation documentation [BZ #28998]
There have been multiple requests to provide more detail on how the _FORTIFY_SOURCE macro works, so this patch adds a new node in the Library Maintenance section that does this. A lot of the description is implementation detail, which is why I put this in the appendix and not in the main documentation. Resolves: BZ #28998.
