Remove rdev packing
Remove custom code to pack/unpack dev_t's. Under Linux all dev_t's are an unsigned 32-bit value even on 64-bit platforms. The lower 20 bits are used for the minor number and the upper 12 for the major number. This means if your importing a pool from Solaris you may get strange major/minor numbers. But it doesn't really matter because even if we add compatibility code to translate the encoded Solaris major/minor they won't do you any good under Linux. You will still need to recreate the dev_t with a major/minor which maps to reserved major numbers used under Linux. Dropping this code also resolves 32-bit builds by removing the offending 32-bit compatibility code.
