d09de0a0d3 Integrate RDLN input buffer into sysvars
In the beginning of Collapse OS' Forth version, the readline sub-
system was optional. This is why we had this separate RDLN$ routine
and that the input buffer was allocated at boot time.

It's been a while since the RDLN system has been made mandatory, but
we still paid the complexity tax of this separation. Not anymore.

b12ac4b672 doc: fix PS/2 recipe
During the recipe overhaul, I forgot to carry PS/2 schematics over.
Also, the recipe should go in hw/z80 because it's specific to Z80.

Having the signature generation code in /tools prevents self-hosting
on the SMS.

7001446212 Complete overhaul of recipes
Recipes contain bits and pieces of hardware-related knowledge, but
these bits feel sparse. I've been wanting to consolidate hardware-
related documentation for a while, but always fell at odds with the
recipes organisation.

We don't have recipes anymore, just a /doc/hw section that contains
hardware-related documentation which often translate to precise
instructions to run Collapse OS on a specific machine.

With this new organisation, I hope to end up with a better, more
solid documentation.
