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...

1dec33e02a zasm: make symbol registry a bit more straightforward 
Instead of strings of variable length driving the iteration of the
registry, we do so through records that keep track of lengths and
counts.

311d04e9aa zasm: make symbol registry easily parametrizable 
I'm about to split the global registry in two (labels and consts)
and the previous state of registry selection made things murky.
Now it's much better.

34f499184d zasm: add ".bin" directive 
Also, remove zasm/test7 because it changes too much all time time
(whenever zasm changes) and isn't precise enough. Too much noise,
not worth it.

1a5a1b9861 ed: make scratchpad memory only 
The dual scraptchpad thing doesn't work. Things become very
complicated when it's time to write that back to the file. We
overwrite our contents and end up with garbage.

942d2a952d ed: take filename as an argument 
This hard-binds ed to the filesystem (I liked the idea of working
only with blockdevs though...), but this is necessary for the
upcoming `w` command. We need some kind of way to tell the
destination to write to truncate itself.

This only has a meaning in the filesystem, but it's necessary to
let the file know that its registered file size has possibly
shrunk.

I thought of alternatives that would have allowed me to keep ed
blkdev-centered, but they were all too hackish to my own taste.

Hence, this new hard-bind on files.

fe15bafeca zasm: fix bug with registry selection 
During expression parsing, if a local label was parsed, it would
select the local registry and keep that selection, making
subsequent global labels register in the wrong place.

4327153ffd zasm: fix include EOF detection 
That was an interesting bug. It didn't cause a problem in emulation, but
in an RC2014 on an SD card, an include that didn't end with two newlines
would cause an infinite loop.

92a04f4627 sdc: support 24-bit addressing 
Needed if we want to compile the kernel and zasm from within a SD card.
I didn't go straight for 32-bit because it was significantly more
complex and 24-bit give us 16M. Enough to go on for a while...
