[stella] Macros to manage memory allocation.

[R Mundschau]

Yes, that code is exactly what  I am doing.  I should note that you  
don't need to put all you ALLOCATE macros together.  They can be  
scattered throughout your source files as long as INIT_ALLOC appears  
before any instance of ALLOCATE at compile time.  I want to be able  
to build up a library of subroutines in include files, then include  
as many as I like in a project and have DASM figure out all the  
allocations for me.

Cheers!
Rob
