NAME
        AddMemList - add memory to the system free pool

   SYNOPSIS
        AddMemList( size, attributes, pri, base, name )
                     D0      D1        D2   A0    A1

        void AddMemList(ULONG, ULONG, long, aptr, strptr);

   FUNCTION
        Add a new region of memory to the system free pool.  The first few
        bytes will be used to hold the memheader structure.  the remainder
        will be made available to the rest of the world.

   INPUTS
        size - the size (in bytes) of the memory area
        attributes - the attributes word that the memory pool will have
        pri  - the priority for this memory.  CHIP memory has a pri of -10,
               16 bit expansion memory has a priority of 0.  The higher the
               priority, the closer to the head of the memory list it will
               be placed.
        base - the base of the new memory area
        name - the name that will be used in the memory header, or NULL
               if no name is to be provided.  This name is not copied, so it
               must remain valid for as long as the memory header is in the
               system.

   NOTES
        *DO NOT* add memory to the system with the attribute of MEMF_KICK.
        EXEC will mark your memory as such if it is of the right type.
