parts/z80/sdc: new part

Incomplete, but what it does *does* work. I could handshake CMD0+CMD8 on
a MicroSD HC.

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`

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.

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.

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.

Separate shell and acia input buffers
...
They serve a different purpose. The goal of the ACIA buffer is to ensure
that we don't miss an input. The goal of the shell buffer is to wait
until the user presses return.
The ACIA buffer has been moved to shell and replaced with a circular
buffer, a more appropriate data structure for this kind of purpose.
Also, introduce `aciaGetC`.
