emul/z80: add SD card support to SMS

It works (in emulation, but soon on real hardware!), but the LIST
command is awkward due to tight screen estate...

also, verify all 3 first bytes of SPI commands. I'm not sure why
I wasn't doing that, probably because I was getting a lot of AVR
err and thought that only 2 bytes of the cmd were echoed. But now,
with a reliable SPI setup, verifying 3 bytes seems to work.

The idea is to consider assemblers as "runtime" apps instead of
placing them in the "bootstrap" section of the blocks. These apps
will be used for much more than bootstrapping.

By default, it changes nothing, but it allows interesting

I've also updated the EEPROM recipe to upload directly to 0x2000.
I'm not sure what has changed, but it's working fine now.

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.

spi: add SPI_DELAY decl
...
AVR chips often run at less than z80's system clock. This means that
our SPI relay needs to have its own clock to properly communicate
with it. This means that the delay between OUT and IN can't be
hardcoded to 2 NOPs anymore. It needs to be configurable.

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.
