Since ino_t size is about to change to 64-bits, replace ino_t used in dump protocol definition with 32-bit dump_ino_t to preserve backward compatibility. At some point, it may be necessary to use spare fields in struct in order to fully support 64-bit inode numbers. Sponsored by: Google Summer of Code 2011
