z80a: make mnemonic names more uniform across assemblers Initially, I used the same letters as those used in the z80 ref docs, but it makes the different assemblers harder to use than they should. Having consistent "argtype" rules across assemblers should help.

Refer to BOOT and (uflw) by addr in stable ABI Was previously referred to by name+find, which was wasteful.

Make word routines into word types Instead of having wordref point to core word routines, I made them into word 4 word types. It liberates space into the stable ABI and should make porting to other arches easier. I'm also thinking of combining word type with the namelen field for precious bytes saving, but not now...
