9f75d1a6b5 the get_byte method needs to take mutable reference to self 
the reson for this is it's possible for external hardware to have some
side effect on a read.

f3f15de8cc remove memory.get_slice

131b0f312d remove get_byte_mut_ref method from Memory 
This is the right thing to do, because the actual hardware will perform
a read and then perform a write. This could have observable side effects
on a real system
