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.

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.

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.
