Michel Heily bce4456f42 [breaking-change] Remove game ROM and bios from savestate file. 
This breaks the API of GameBoyAdvanvce::save_state and restore_state methods.
Currently as WIP only SDL2 frontend will adjust.

Michel Heily 0de8a60006 core: Start working on a scheduler 
A more robust cycle aware event scheduling, to easily implement serial-io, dmg audio channels and improve accuracy.
This brings a slight performance hit :/

I also ran dos2unix on some of the files :D

Michel Heily dc7cd24e8d [perf] Refactor&Optimize inner core::arm7tdmi APIs. 
Avoid passing ArmInstruction struct to handlers, as accesses to its fields can result in memory operations.

Michel Heily bf601404fa Optimize cartridge Bus reads 
The `if let Some(gpio) = &self.gpio` causes a memory read of `self.gpio` for every Bus::read/write_16.
It is better to reverse the order since `is_gpio_access` does not generate and memory reads and thus less costly.

The code was cleaned up quite a bit, but I may have introduced new bugs
in this process :<
