test: begin adding common test harnessing code This should make tests a bit more convenient to write and debug. Moreover, begin de de-IX-ization of parseExpr. I have, in a local WIP, a parseExpr implemented using a recursive descent algo, it passes all tests, but it unfortunately assembles a faulty zasm. I have to find the expressions that it doesn't parse properly. But before I do that, I prefer to commit these significant improvements I've been making to tests harness in parallel of this development.

.inc "core.asm"
Extract str.asm from core.asm and make core included by userspace Most of register fiddling routines (which is now the only thing contained in care.asm) are used by almost all userspace apps, often in inner loops. That makes the penalty of using jump tables for those a bit too high. Moreover, it burdens jump tables needlessly. Because this unit is very small (now that string routines are out), it makes sense to always include it in binaries.
