There is no reason in principle that an svn-format dump would not be able to represent a file whose length does not fit in a 32-bit integer. Use off_t consistently to represent file lengths (in place of using uint32_t in some contexts) so we can handle that. Most svn-fe code is already ready to do that without this patch and passes values of type off_t around. The type mismatch from stragglers was noticed with gcc -Wtype-limits. While at it, tighten the parsing of the Text-content-length field to make sure it is a number and does not overflow, and tighten other overflow checks as that value is passed around and manipulated.
