[En-Nut-Discussion] NutHeapRealloc

If it's going to find it's way into Nut/OS yes, but I didn't implement 
it, because I'm developing with BTnut ( http://www.btnode.ethz.ch/ ), 
which is built on top of Nut/OS but does not use nutconf, as it's 
developed for a special node. Of course you can set the defines directly 
in the code if you wish. I'm also not really expecting all the code to 
go into Nut/OS, but maybe someone wants to add snippets of it. It also 
might be reasonable to do some cleanup. But I'm not going to do this as 
long as it's not going to be used by anyone but me.

Cheers
Morty
