- Wrap static globals with a mutex.
- Implement InputInterface
Testing this on a standalone Java Console Application (without
rendering) shows sufficiant performanse for now (AVG fps of 180 in the bios)

I should really pay more attention to the docs..
The previous fix (bb843ea5) was not enough as it caused vblank,hblank
and vcount-match flags to be overwritten when they really should have
just been ignored.
This caused Dragon Ball - Advance Adevnture to fail booting

Initially I began implementing the gdb protocol on my own, but I then found a
nice work-in-progress crate on https://github.com/daniel5151/gdbstub
that suited my needs.

For some reason, probably typing mistkae, I `or`ed the value being written to DISPSTAT,
causing bits to never actually turn off, affectivly making HBLANK/VBLANK
interrupts linger forever.
This probably has caused some nasty glitches that I don't even know of, but two confirm issues solved
by this are Mariokart and Pacman.
This commit fixes#14 and #13

Ran cargo-fix to automatically fix most of the build warnings,
Cleaned up dead code, and fix the rest manually

Move reload_pipeline calls inside instructions.
This commit yeilds yet another 5% performance improvment.
The next step is to move `advance_pc` into the instructions themselves
and save the `match result` per executed instruction

In preperation for later optimization in the CPU pipeline
implementation, this commit refactors the arm/thumb exec functions to return a
CpuAction (Whether to advance the program counter or to flush the
pipeline)
Currently, a lot of host cycles are wasted in the arm7tdmi pipeline
Refill1 & Refill2 states. Optimizing these steps out would make the CPU
a bit faster.

This commit removes the error handling (CpuResult<>) in order to reduce
overhead in the cpu implementation.
Also, some cleanup of warning messages.
Notice: this commit breaks '--feature debugger' for now

This change fixes#9 and emulates:
- Correct layer ordering
- Correct emulation of blending sfx
- Correct emulation of the object window (BIOS boot animation is now fixed)

Removed unused code and added meaningful log message to indicate eeprom size assumption due to save file size

The docs state: "If a register is used to specify the shift amount the PC will be 12 bytes ahead"
I probably misread that when implementing DataProcessing instructions,
and because of that added 4 bytes to (op1+8) when shift amount was specified by a rotated immediate.
Fixes#6 (and probably tons of other bugs too!)
