013a3b74c8 Add the concept of unit tests 
Will be much much easier to tests new core routines without having to
re-create their context first.

Also, extract parse.asm from core.asm

ede228374c fs: allow fsNext to skip more than one block

1ea5bedb4f blockdev: fix broken blkSeek/blkTell 
scas didn't warn about this, but it seems that `jr` calls were out of
range. Seek and Tell was broken. Replacing `jr` with `jp` does the
trick.

34ee91a0d7 zasm: use blkdev IDs as input and output 
This will soon allow use to seek and tell on input, which is necessary
for a second pass which is necessary for forward symbol references.

This require making `blkSel` a bit more flexible. Rather than having one
global selected blkdev, each app can select its own, in its own memory
space.

ef11059382 parts/z80/sdc: new part 
Incomplete, but what it does *does* work. I could handshake CMD0+CMD8 on
a MicroSD HC.

a391f85c00 fs: implement GetC, PutC, Seek and Tell on file handle

f00334ec89 fs: add private "blk" routines 
This way, we can interact with the mounted FS even when we change the
selected blkdev.

3ba0a707e7 blockdev: remove a layer of indirection in block routine storage

5eca14d49a fs: implement fsNext 
This allows more than one file to be allocated. `fls` properly lists
multiple files.

c0dbee78de New part: fs 
Very incomplete, but if you play your cards right, you can, with the
shell:

1. Create a new CFS
2. Mount it
3. Allocate a file with an arbitrary name
4. Have it listed with `fls`

07fde3cab5 blockdev: move the new seek mode logic into the seek command 
It wasn't a good idea to complicate all blockdev impls with complicated
seeks. Let's just stay in absolute mode for now.

f87cd0485a blockdev: make "seek" print out its resulting position

dependent on stdio.

1bcceb949c blockdev: add Tell and fix blkGetCW 
Calling on blkGetC repeatedly was somehow very unstable and often
failed. I didn't pinpoint exactly why, but keeping the call addr around
and calling that instead seems like a better idea anyway.

b4694225c5 blockdev: change GetC API 
Instead of waiting, GetC always return immediately, with Z indicating if
something was fetched. The "wait" loop is implemented by the called (and
in the new `blkGetCW`).

This simplifies out-of-bounds verifications for storage blockdevs.

fc0cdede55 Move print(n)str from core to shell

ff99062d5b Move RC2014 recipe in its own folder 
Also, remove `parts/platforms`. It makes no sense. Only recipes make
sense.

The approach used for shell extra commands also works for blockdev. Much
simpler and tighter this way.
