Chgrp, chmod, chown, chcon, du, rm performance information on ext filesytems

• Noteworthy changes in release 7.0 (2008-10-05) [beta]

• • New features

 chgrp, chmod, chown, chcon, du, rm: now all display linear performance,
 even when operating on million-entry directories on ext3 and ext4 file
 systems.  Before, they would exhibit O(N^2) performance, due to linear
 per-entry seek time cost when operating on entries in readdir order.
 Rm was improved directly, while the others inherit the improvement
 from the newer version of fts in gnulib.
