Add missing backwards compatibility for ancient Linux systems

This fixes some (but not all) of the compatibility bugs which prevented
e2fsprogs from being compiled on a Linux 2.0.35 system.  There are still
some unprotected use of long long's, and apparently some type problems
with the uuid library, but these can be fixed up later.
