As we are now in 2.5.x series I figured it might be a good time to push
this out...  The patch removes __KERNEL__ ifdefs from [only] io.h as a
nudge to userspace that they should not be including kernel headers.

MDK, RedHat, Caldera, and other distros already distribute a subset of
[sanitized?] kernel headers for glibc, so there is plenty of time to
notice and deal with any breakage this causes in userspace [which IMHO
should not have been including kernel headers in the first place...]

Finally, the patch includes a cosmetic cleanup to use standard
u8/u16/u32 types for {read,write}[bwl], similar to patches already
applied for sparc64, alpha, and other arches during 2.4.x series.
