Update to IOzone 3.408

Changes since version 3.397:

Revision 3.408
Bug fix for clobbering of buffer. "tfile" needed to be bigger, as its
address was loaded into filearray[] and then that was overwritten
by the mfflag causing parsed names to get loaded.

Revision 3.407
Work around for cache_line_size suddenly becoming zero and breaking fetchit()

Revision 3.406
Increase buffer size for configuration lines. They might be 700 chars long.

Revision 3.405
Reduce CPU consumption in the op_rate control mechanism.

Revision 3.404
Fix type-oh in usage message.

Revision 3.403
Add -+W to permit chid_skew. This permits adding files, and continuing
the proper sharing/dedup within each quadrant, within same seed group
and with previously existing files that were created with a different
number of threads.

Revision 3.402
Mods for DragonFly support.

Revision 3.401
bug fix for re-write rec.

Revision 3.398
Adding thread_read_test and thread_write_test.
