63473cc2e3 blockdev: make selection structure opaque
I'm about to change that structure and I don't want fs to be messed up
by this. I'm proceeding step by step...

95f1a8ddaf blkdev: make load command stop and the end of the stream
This allows us to reliably and easily load a file until the end of it.

73c3fc7947 shell/stdio: decouple from blkdev (again)
Move load/save to blkdev_cmds and add a new "poke" builtin shell cmd
that is the mirror of "peek" and strictly uses stdio (no blkdev
involved).

This allows us to slim the minimal OS size but, more importantly, change
the behavior of "load" so that we don't expect GetC to block until Z is
set. This way, using "load X" with X being larger than the blkdev size
won't block forever.

This also brings our RC2014 minimal kernel below the 1K mark again.

So that blkdev not supporting 32-bit aren't messed up.

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.
