Subject: Eliminate wrapping of struct stat and use the kernel version
directly. Eliminate all the attendant baggage. Fix internal types to match
kernel types more closely. -Erik

-/* To allow the `struct stat' structure and the file type `mode_t'

- the `stat' family of functions and `mknod' are in fact inline
- wrappers around calls to `xstat', `fxstat', `lxstat', and `xmknod',
- which all take a leading version-number argument designating the
- data structure and bits used. <bits/stat.h> defines _STAT_VER with
- the version number corresponding to `struct stat' as defined in
- that file; and _MKNOD_VER with the version number corresponding to
- the S_IF* macros defined therein. It is arranged that when not
- inlined these function are always statically linked; that way a
- dynamically-linked executable always encodes the version number
- corresponding to the data structures it uses, so the `x' functions
- in the shared library can adapt without needing to recompile all
- callers. */
