c6feb5d500 core: Optimizing GameBoyAdvance::frame 
Profiling GameBoyAdvance::frame shows that it spends way too much time idleing
on SoundController::update & Gpu::step waiting for the cycle count to
reach to the next event, Consuming cpu time for the Arm7tdmi core.

This commit changes the implementation of the main loop functions so
that the CPU will run as many cycles as possible and the peripherals
will only be updated when needed.
The is a performance improvement of roughly 50% in fps in some games!

3687161b98 Make the debugger into an optional build option. 
This module is written purely and always breaks when changes are being
made into the 'core' module, so as long as I don't use it, I don't feel
like maintaining it.

5acd7ddd71 Solve the sound clicking issue in Kirby! 
The symptom of the problem was in the form of a rythmic click sound popping in the left channel.

Diving deep into Kirby's binary, I found out that channel B and channel
A are playing too different pcm buffers simultationsly: A is enabled for
the right channel and B is enabled for the left.

I found out that the game's sound driver was using VCOUNT in order to syncornize the audio,
but in some occassions the fifo DMA was not disabled in time, causing the DMA to
fill the fifo in additional 16 bytes of garbage residing next to channel
B's pcmBuffer.

After a thorough check-up of the GPU state machine, I find out that I
stay in VBLANK for 1 line too long, and that's what caused the audio
buffer to de-sync with the gpu emulation.

This commit fixes this issue.

addresses, and initial length. The hardware does NOT change the content
of these registers during or after the transfer.

The actual transfer takes place by using internal pointer/counter
registers. The initial values are copied into internal regs under the
following circumstances:

Upon DMA Enable (Bit 15) changing from 0 to 1: Reloads SAD, DAD, CNT_L.

Upon Repeat: Reloads CNT_L, and optionally DAD (Increment+Reload).

b288625b9a Improve the debugger 
- Add tracing of opcodes and potentially more stuff
- Add option to run a script file at the beginnig (I use it to redirect
traces to a file)
- Support breakpoints again

1d088accb8 mGBA test suite now boots! 
Fix tons of bug and reimplemented some of the core code.
Add a neat feature for debug builds:
When the cpu "swi 0x55" instruction, a breakpoint is triggered on the
host.

c78a111ad4 Implement DMA, WIP 
I have fought very hard against the rust ownership model,
In the end for DMA to play nice with my code, I had to resort to use
unsafe code for now..

The DMA implementation itself is not accurate to say the least, but will
have to do for now.

Tonc's dma_demo.gba plays but with a visual glitch.

2bd8b56bc6 Fix that DAMN bug. 
Long story short, I've been hunting this bug for a while now.
While passing armwresteler tests, I still had an emulation bug which
causeed libgcc's iprintf to produce bugged strings.

In order to find it, I've used https://github.com/fleroviux/NanoboyAdvance/
And patched it to produce a formatted log of every step of the execution
of iprintf:
{OPCODE} {PC} {R0} {R1} ... {R14} {FLAGS}
Did the same on my emulator and searched for differences.

Found out the a "CMP r3, #0x0" instruction turned off the carry flag
when it shouldn't. Found this sad function, the check I'm using for
carry flag is meaningless when done on signed integers. :sigh:
