MDS size overflow patch

When I try to read mounted with cdemu mdf/mds image at amd64 arch computer I got such errors in dmesg: "attempt to access beyond end of device". This is due known bug in MDS parser where fragment length overflows because it try to store file size into 32-bit int. The issue has been fixed in git already, and the attached patch should apply to libmirage-2.1.1 source.
