This is exactly why I sent out this note!  If folks are still using  
these, then we should keep them.

We're slowly removing them anyway, but perhaps we could replace them  
with something smaller and cleaner?

Perhaps a define like DECODER_DEUBG("my great message %s",  

There are a couple problems with the existing approach:

1.  It's big and ugly.  (3 lines for a little log)
2.  If you don't use the #ifdefs, due to the c++ stream syntax, there  
is no way to no have everything right of << not executed at runtime,  
for example:
kdDebug(123) << doSomethingReallySlowly() << touchABunchOfMemory()  

These are some of the reasons why we've been slowly removing these  
blocks (both the ifdefs and the raw kdDebug(123) stuff).
