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.

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.

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.

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.

tools/tests: remove scas requirement
...
I'm about to break compatibility with scas. Before I do that, I
need to adjusts tests. Instead of running scas to compare results,
we commit expected result as binaries directly in the repo.

blockdev: protect IX in routines
...
Sure, it's a bit slower, but it prevents a lot of hard to debug
problems. I don't have to want to remember "don't use IX if you
have any blk* calls". Let's optimize I/O later.
