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.
