Subject: Updated fsx.c program

I've done some work to merge some of the existing fsx.c mods into a
single version.  Over & above the version that is in the LTP, I've
included AKPM's O_DIRECT fixes (with a twist), the BSD mmap page and
segfault handling, and per-write fsync.

The twist for the O_DIRECT feature is that it will randomly open file
descriptors with O_DIRECT, and if you use the Lustre-inspired multi-fd
support fsx will be testing concurrent buffered and O_DIRECT and mmap
IO on the same file.

Cheers, Andreas
