This makes us more independent from emscripten libraries, giving us more control on the application lifecycle.

I don't think anyone is actively using it, and it's a lot of convoluted code.

In this PR:
canvasPolicy == 2, i.e. default).In an effort to be less dependent on emscripten libraries, this PR drops most of the
emscripten_*function usage in favour of internal JS implementations. This gives us more control over input processing, there's more work that could be done on this (e.g. resuming the AudioContext directly from JS), but this PR is growing already quite big, so I'd rather do that in a separate one.With this, the only emscripten functions left used from C++ are the app lifecycle functions (set/cancel main loop, exit) and webgl related functions (context creation, buffer swapping, GLES compatibility).
