Remove SHELL_LOOPHOOK
...
It was a bad idea and having sms/pad interact directly with sms/vdp
is much simpler.

ASCII_DEL. Also, don't crash on filling the buffer.

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.

pgm: new kernel module
...
The pgm module implements a shell hook so that when an unknown command
is typed, we look into the mounted filesystem and look for a file with
the same name as the command. If we find one, we load it in memory and
run it.

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.
