A lot of test ROMs i'm using don't bother to calculate the checksum :\

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.

Also some typos and reformatting parts of the code

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 :<

Serde doesn't like Rc that much :(

While saving code re-use, it won't allow flexibility for special casing
specific size bus accesses which are much needed in order to emulate
open-bus and bios reads

Use Rc<Cell> instead of passing `&mut irqs` all around.
The runtime impact is two additional size_t's per each holder of the
shared pointer.

According to CowBite, the top bit is supposed to be ignored.

Pokemon Emerald no longer has the "Battery ran dry" message, and RTC
functions work.

This test also caught a bug where hblank flag from the last
vblank-hblank would linger on the next HDraw.
