This allows better understanding of the ROMs and their purpose.

Also fixed small channel 3 issue

There's still no control over the channels themselves, but the basic interleaved buffer support is now coded.
There's also new support for buffer size definition in seconds.

Will allow performance update when not using audio.
Done for benchmark purposes.

Support for set of video, audio and timer.
Now with support for toggling audio in the SDL version.

Makes use of the new emukit audio code.

Now the BIOS beep works perfectly.

The emulator is now sounding more like a real audio player .

There are a series of hacks involved in making a constant stream of audio data to work OK with web audio.

Made use of queue support for SDL avoiding the callback approach which greatly simplifies the code and increases the APU accuracy.

It's stil glitchy and noisy, need to check the problems.

Still requires work to be able to be able to emulate APU together with the CPU instead of inverting the control.

This a very work in progress situation that requires stability.
The most important part is the fact that it's possible for an external entity (SDL) to call an audio tick and get a volume.

This reverts commit b7ce4b6a.

This makes it possible to run Boytacean in Ubuntu using dynamic linking with the native SDL libraries.

For wayland dynamic linking of SDL2 may be required.
