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.

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.
