c18d42f08b fs: further adjust to previous blkdev refactoring 
Previous refacoring broke all seek/tell within fs. fs handles now lost
the responsibility to keep track of current position. It's blkdev's job.

ae028e3a86 blockdev: make implementors "random access" 
This huge refactoring remove the Seek and Tell routine from blockdev
implementation requirements and change GetC and PutC's API so that they
take an address to read and write (through HL/DE) at each call.

The "PTR" approach in blockdev implementation was very redundant from
device to device and it made more sense to generalize. It's possible
that future device aren't "random access", but we'll be able to add more
device types later.

Another important change in this commit is that the "blockdev handle" is
now opaque. Previously, consumers of the API would happily call routines
directly from one of the 4 offsets. We can't do that any more. This
makes the API more solid for future improvements.

This change forced me to change a lot of things in fs, but overall,
things are now simpler. No more `FS_PTR`: the "device handle" now holds
the active pointer.

Lots, lots of changes, but it also feels a lot cleaner and solid.

9a72f10221 zasm: includes CFS is now built on-the-fly by zasm.sh 
This makes for a much more usable zasm linux binary that doesn't have to
be rebuilt every time apps or kernel change.

22e990ed89 Parametrize zasm linux bin's include CFS file 
... instead of embedding it in the binary itself. Additionally, add a
"zasm.sh" wrapper to faciliate zasm calls on a linux machine.

328f44814e Make blockdev pointers 32 bits 
This allows us to break through the 64K limit for includes CFS in zasm,
a limit we were dangerously close to breaking. In fact, this commit
makes us go over that limit. Right in time!

af2c561c6b zasm: begin erroring out reliably 
Up until now, invalid source input had undefined behavior. We're now
beginning to define that behavior so that zasm can be a bit more usable.

bc1496a7e3 zasm emul: bring back kernel/user distinction 
It was a bad idea to remove it. Now that I'm introducing the concept of
a per-app glue file, it becomes much easier to build emulated zasm as a
userspace app.

7fad3b0c90 Move /parts/z80 to /kernel 
Let go of that "meta os" thing. it's not as meta as I made it sound
like. It's a kernel.
