ABI change: fix use of off_t, size_t, and integer types

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.

  * Building 64-bit libraries with MSVC works with existing build.sh as
    long as the x86_64 version of the compiler is in the path.
