Significantly improve the code's use of off_t for file offsets, size_t for memory sizes, and integer types in cases where there has to be compatibility with external interfaces. Rework sections of the code that would have prevented qpdf from working on files larger than 2 (or maybe 4) GB in size.

|
|
// finish() and before calling any subsequent write(). At that point,

// a dynamically allocated Buffer object is returned and the internal

// buffer is reset. The caller is responsible for deleting the

// For this pipeline, "next" may be null. If a next pointer is
