Been wanting to do this for a long time.
This does impose performance issues when building with the vanilla
release profile, as cargo does not perform optimizations across crate
boundary (we care mostly about inlining).
so I added release-lto profile
Also fixed some broken stuff I found across the project, meh

* Convert gpu bitfield!() registers to unpacked form, and defer pack/unpack to bus read/write operations

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
