libtar: fix size computation of PAX line length
This commit attempts to fix the following two problems: - The number of digits computation returning an off-by-one result if the number is 10, or the resulting digit string starts with "10". This results in one-too-many padding bytes, corrupting the rest of the archive since the headers now don't start at multiples of 512 anymore. - Adding the line length prefix affects the line length (duh). If it grows far enough to require more digits, the result is a similar problem. This is a converging series that we need to compute the limit of. Unit tests for this still need to be added. Or maybe I can convince a bored undergrad student to provide an induction proof. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
