Virgil Dupras 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.

z80 assembler

This is probably the most critical part of the Collapse OS project. If this app can be brought to completion, it pretty much makes the project a success because it ensures self-reproduction.

Running on a "modern" machine

To be able to develop zasm efficiently, libz80 is used to run zasm on a modern machine. The code lives in emul and ran be built with make, provided that you have a copy libz80 living in emul/libz80.

The resulting zasm binary takes asm code in stdin and spits binary in stdout.
