Michel Heily d9ce1c7d8d optimize/arm: Improve arm instruction condition check.
Obviously AL(always) instructions are the most common, so prioritize checking these first.

Michel Heily c5b9c68d5e feat/jni: Cleanup & Improve jni bindings
- 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)

Michel Heily c68b9502fe bugfix: Fix bad write impl of DISPSTAT again.
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

Michel Heily c50ab1ecd8 feat: Add basic gdbserver feature
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.

Michel Heily c96fa38a2d bugfix: Fix improper write to DISPSTAT register
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

Michel Heily 32a20d2cbb ptimize: CPU Pipeline optimization part 3
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

Michel Heily 1f79205f51 optimize: CPU Pipeline optimization part 1
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.

Michel Heily ae7bf63d3f arm7tdmi/optimize: Optimize and cleanup CPU, roughly about 10% fps improvement.
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
