8e89ed067a CPU emulator should not try to emulate peripherals. 
Especially in a lame/incomplete way. These should be later
re-added in examples.

2cc9d86c64 Simplify error handling if malloc fails. 
There's no way to reliable handle out of memory situation in an
emulator. So just bail out by raising assertion.

b7986df553 Split address calculation into separate function. 
This removes some code duplication for instruction_data_read/write
functions. Also this way implementing watchpoints will be far easier.
