Make blockdev pointers 32 bits This allows us to break through the 64K limit for includes CFS in zasm, a limit we were dangerously close to breaking. In fact, this commit makes us go over that limit. Right in time! 2019-05-29 05:56:39 +10:00			`jp test`

zasm: Constants now override labels at all times Will be important for a mega-commit I'm preparing. 2019-11-15 13:16:36 +11:00			`dummyLabel:`

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. 2019-06-05 01:53:02 +10:00			`; *** Just little z80 flags memo.`
