7a0e63746f parse: don't validate 0x and 0b lengths
It doesn't serve much purpose and takes up many precious bytes. And,
after all, parsed didn't do it either...

dfaa1dc101 link: add "offset" argument to RLDICT
As long as our target was the first word of the "user" dict, using
target's prev to compute offset was fine, but when the target is not
the first word, this system breaks down.

This is the case when, instead of including source code in our boot
binary, we paste it in Collapse OS' prompt.

Also, adjust RC2014 recipe to include stage 3 assembling instructions
with the "paste into prompt" method.

a2d89de557 drv/sdc: implement core words in z80
In addition to making the driver significantly faster, it allows us
to make SDC port configuration opaque to sdc.fs.

d0545d555f upload: use A! instead of C!
It makes the tool much more versatile. I'll have adev being included
in all recipes, so it can be assumed.

d08a9711c5 boot: make HERE point to RAMEND instead of CURRENT
The former was only used in the peculiar context of "/emul". The
regular case is actually HERE pointing to RAMEND on boot.

6368cc3bac Remove (sysv)
Replace its usages with direct RAM+ offsets. The (sysv) mechanism was
incompatible with cross-compilation of a full interpreter.

92ddc7ebc1 recipes/trs80: use grid module
Not much of a gain in terms of usability (a bit of a loss in fact, things are
a bit slow and glitchy), but it's a necessary move if we want to use upcoming
grid-enabled userspace apps, such as a visual text editor.

049f2cf222 Reverse ttysafe escaping order
Sending the escape after its target made things complicated for upcoming
stuff I want to add. Although it makes `recv.asm` slightly larger, it's really
worth it.
