[PATCHES] MSZIP support for cabinet files

[Aurélien Aptel]

Thanks for merging.

Some updates about fuzzing: I've let AFL run for 4 days and it found no
crash so far which I know doesn't prove anything but conforts me that
the pull code is probably safe. A better test would be to fuzz that +
the thing that actually uses the resulting pulled cab structure.
