Add 64-bit directory entry structures, and adjust accessors accordingly.
The LFS64 directory entry has a 64-bit inode number. This is stored as two 32-bit values to avoid inducing 64-bit alignment requirements. The exposed type for manipulating directory entries is now LFS_DIRHEADER, following the same convention as e.g. IFILE and SEGUSE. (But with LFS_ on it, because.)
