bug#6186: du in coreutils should add the -d flag as a shortcut to --max-depth

[Jon Ringuette]

So here is my first whack at it.  One thing to note is there was a DU_DEBUG 
optional define that defined a -d flag to use for debugging.  It seemed like 
using -d would be more useful for everyone to use for depth then for debug so I 
modified the slightly oddly thrown in debug stuff to now work with --debug 
instead.  Though when I actually define DU_DEBUG so the #if DU_DEBUG is picked 
up and used it complains about the function missing so I'm kind of curios if 
this has worked for awhile.

Anyways any feedback or recommendations would be greatly appreciated so this 
has a better chance of making its way into the release.

Thank you for your time on this matter!
