kientzle 2276f34c5f Extended attribute support on write for Linux; FreeBSD hooks are
forthcoming.  This commit also has a number of style(9) fixes and
minor corrections so the code works better with the build system being
used for non-FreeBSD builds.

Many thanks to: Jaakko Heinonen, who proposed a mechanism for extended
attribute support and implemented both the machine-independent portion
and the Linux-specific portion.
