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.

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.
