Wasn't expecting such an improvment tbh, but who am I to argue with results

It's quite an handy way to log messages from ROMs, so I thought it'd be nice to add it.

Some big refactors:
* improve scheduler performance by using a BinaryHeap
* refactor the scheduler API
* arm7tdmi
* Change struct arm7tdmi::Core struct layout so frequently accesses fields would benefit from CPU cache
* Simplify and cleanup cycle counting by implementing a MemoryInterface trait
* Still not passing many cycle accuracy tests, but I believe it's because I don't have the prefetch buffer yet.
* Timer overflows are now scheduled
* This fixes#111 and fixes#112
*

This breaks the API of GameBoyAdvanvce::save_state and restore_state methods.
Currently as WIP only SDL2 frontend will adjust.

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

Avoid passing ArmInstruction struct to handlers, as accesses to its fields can result in memory operations.

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.

Mainly convert mainloop and audio thread into native code for
performance increase. (Calling into JNI every frame was costy)
The code was cleaned up quite a bit, but I may have introduced new bugs
in this process :<
