2a55bfd375 stdio: remove a layer of indirection in GetC/PutC
We use zasm's ability to use labels in .equ directive.

We didn't do it before because for a while, we were in between scas
and zasm (scas was used in automated tests) so we needed to use the
lowest common denominator: zasm doesn't have macros and scas can't
use labels in .equ directives.

This forced us to add this layer of indirection. But now that we are
completely cut from scas' dependency, we can use this nice zasm's
ability.

b745f49186 Rename blockdev's API routines to GetB/PutB
The goal is to avoid mixing those routines with "character devices"
(acia, vpd, kbd) which aren't block devices and have routines that
have different expectations.

This is a first step to fixing #64.

Otherwise, we overflow into the RAM mirror, which means we
overwrite the beginning of the RAM.

af0b6231ca recipes/sms/romasm: make ed's memory usage fit the SMS
Yup, that's ultimately why I've just made this whole big zasm
refactoring in the previous commits. To allow for this.

But also, zasm is in much better shape now...

Forward reference of SHELL_MEM_PTR wasn't working (nor should it
have been...).
