cbfstool/lzma: Avoid use of typedef with structs and enums

When typedef is used with structs, enums, and to create new typenames,
readability suffers. As such, restrict use of typedefs only to
creating new data types.

The 80 character limit is intentionally ignored in this patch in order
to make reviewing easier.
