1a6a549857 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.

a70366aa43 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.

9c41744e46 emul/hw/rc2014: implement blk write in sdc
All of that should help me implement sdc support much faster in
Forth.

ae470397d7 emul/hw/rc2014: add sdc emulator (wip)
so far, it goes through initialization with the rc2014/sdcard recipe.

Why didn't I think of adding it before?

9216057db8 emul/hw: add TI-84+ emulator
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).
