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.

124da6adec Move SD Card subsystem outside of RC2014 recipe and add protocols
Although the SPI Relay driver is RC2014-specific, the SD Card driver
is generic enough to be a subsystem. That's the second subsystem we
add and this warrants, I think, the formalization of a new concept:
protocols.

bd38d80f9c Move Cross-compiled core from B390 to B350
and renamed it "Core words". Also, reworded the presentation.

db9885b8cf Rename (find) to FIND
I hadn't noticed that this word was almost ANS compliant.

ca60685067 Streamline initialization process
Instead of letting each configuration taking care of RDLN$ and
"CollapseOS" prompt, move this to BOOT to simplify xcomp units.

Initialization source code is now only for driver initialization.

74896051bb Move BOOT, (boot<) and INTEPRET to high xcomp
Saves us an (ok) indirection and will save us more soon.

TODO: implement X['] so that I can remove those XCURRENT patterns.

cbf5baf3b6 Pack core words a bit
This leaves space for xcomp-core which is growing.

1094ec9c57 Make DO..LOOP stable
DO and LOOP now only compile words from stable ABI, which make them
suitable for xcomp. This will greatly simplify driver writing and
allow us to mostly avoid the low/high divide in drivers.

LEAVE is still xcomp-incompatible though.

This make us very very tight for "<0x100" limit for literal words.
Hopefully, we won't need more stuff in that area of the binary...

f54b1dc504 Add 2>R and 2R>
This allows us to make DO..LOOP more compact.
