Move print(n)str from core to shell
...
These routines had hardcoded references to ACIA and didn't belong to the
core.

For now, only a dummy app, but it's emulated properly with libz80.
Exciting times!

Move RC2014 recipe in its own folder

Also, remove `parts/platforms`. It makes no sense. Only recipes make
sense.

blockdev: remove one layer of indirection

The approach used for shell extra commands also works for blockdev. Much
simpler and tighter this way.

Separate shell and acia input buffers
...
They serve a different purpose. The goal of the ACIA buffer is to ensure
that we don't miss an input. The goal of the shell buffer is to wait
until the user presses return.
The ACIA buffer has been moved to shell and replaced with a circular
buffer, a more appropriate data structure for this kind of purpose.
Also, introduce `aciaGetC`.
