Michel Heily 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!

Michel Heily 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.

Michel Heily d8545dd8cd sdl2: Use callbacks with ring buffer instead of audio queue. 
Better latencies, and also fast-forward (aka Turbo mode) sounds normal
this way.

Michel Heily 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.
