PR 78534, 83704 Handle large formatted I/O
In order to handle large characters when doing formatted I/O, use
size_t and ptrdiff_t for lengths. Compared to the previous patch,
based on discussions on IRC use size_t for sizes that don't need to be
negative rather than ptrdiff_t everywhere.
Regtested on x86_64-pc-linux-gnu, approved as part of the PR 78534
approval, committed to trunk.
