[Crash-utility] [PATCH] Add support for byte swapping in rd

Dave, I often do analysis on network-releated crashes and often find myself doing mental byte swapping to convert from host to network and back - I think crash can do it much better then me, so I wrote a patch to teach rd how to do this. I'm only doing byte swapping on 16 and 32 bit types because 64 bit integers don't have a "standard" network representation. max
