In tgt.c we used fprintf not the openjpeg message reporter

In tgt functions the message manager is not available so some messages are not correctly
return to the user. 
It is very complicated to pass this manager to these functions, so for the moment we
use fprintf.
Moreover we need some documentations about the case where we used fprintf to return
warnings.

Hi, 

With SVN revision 2343, the trunk still use fprintf messages (e.g. inside image.c,
openjpeg.c, tgt.c). 
This is very problematic (better print nothing and return an error). 
There are also many fprintf calls that are commented => should be deleted. 

Please add this correction on top of the priority list.
