emul/rc2014: add support for Zilog SIO
...
Very very simplistic, but works with our driver.

Make the SPI Relay protocol support multiple devices
...
Working on programming AVR chips exposes a glaring omission in my
first design of the SPI Relay: not allowing multiple devices make
this task hard. I constantly have to unplug my SD card before, plug
the AVR chip holder, then play a bit, then unplug the AVR holder,
then replug the SD card...
My prototype for a SPI relay design is built, but I haven't tested
it yet. I need to adapt the code first, which is what I do here.
When the prototype is tested, I'll update the SDC recipe with a new
schema.

Gave more priority to CPU in the emulator because initialization would
otherwise be horrendously slow.

drv/sdc: Implement SDC!
...
This has been tested in the RC2014 emulator. I could edit blocks with
the Block Editor and they would correctly be written to SDC.

All of that should help me implement sdc support much faster in
Forth.

VDP kinda works. Can see the Collapse OS prompt with SMS base recipe
if `STDIO_GETC` gets replaced with infinite loop (no input emul yet).

I implement the screen using XCB which is much more friendly
than z80e's SDL+CMake for development machines that want to install
minimal dependencies (for example, a port-less OpenBSD rig).
