Virgil Dupras 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.

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.
