lib/string_helpers: rework overflow-dependent code
When @size is 0, the desired behavior is to allow unlimited bytes to be
parsed. Currently, this relies on some intentional arithmetic overflow
where --size gives us SIZE_MAX when size is 0.
Explicitly spell out the desired behavior without relying on intentional
overflow/underflow.
