Use proper signedness for the LIF file system data structures.
Ancient 4.3BSD used short and int for location, file size, file type, and addresses etc. but all of them should be unsigned. Also rename several variables and add comments for readability. The LIF file system info can be found in "The HPDir Project" page: https://www.hp9845.net/9845/projects/hpdir/ The same uboot.lif binaries are generated.
