Only VCD export works, but the PR also contains some new features :

  • variable number of cycles per instructions. Traditional is 12T, but some are 2T and most current are 1T
  • enhance the history output when multicycle instructions are executed. This is important for more accurate VCD files
  • enhance the RESET. Can do proper Power cycles & IDLE.

Move the init to opcode/disasm calls to emu.c

It is a plaform setup task, there is little point in reloading it upon
reset.

Only the call is delegated to emu.c, the function itself is still in
opcodes.c & disasm.c

Enhance the RESET capabilities

Now able to emulate:

* Warm RESET (only SFR)
* Power-Cycle RESET (SFR + RAM)
* Factory RESET (SFR + RAM + ROM)
