Sooner or later we will need to add tests to check for regressions.

I propose the following three kinds of tests:

• Function unit tests (mainly for the parsing functions)
• I/O testing: simulate a client sending requests from a different process and check the responses are correct
• Internal state testing: simulate a client sending requests from a different process and check our intern

The font bitmap has empty space reserved for ASCII characters 0x80 through 0xA0.

We should use that space for something, like icons for WASM-4 controller buttons, or generic sprites like stars/hearts/etc.

Games can then use hex string literals to easily display these:

text("Press \x80 to jump!", 0, 0);

This can be applied to the pmm, vmm, pit, rtc, pic, isr, irq and maybe more.

Replace usage of @bitcast with safer alternatives, it needs to work in debug builds
