Move icore to blkfs The way is clear for complete stage1 bootstrapping on the RC2014 target!

Replace INITIAL_SP with PS_ADDR conf Now I struggle to remember why I ever did things they way I did. There must have been a reason...

xcomp: add XCOMPILE and X[COMPILE] This allows us to move words like ABORT" to xcomp-core, which is I think the last roadblock before being able to unify all drivers into a single xcomp layer.

Add xcomp unit for cross compilation Memory mapping is a dead end too, solution has to be at a higher level. xcomp is my new approach.

emul: bootstrap to stage2 from within Collapse OS! Big bootstrapping change which greatly reduces the role of the modern operating system in the bootstrapping process.

xcomp: move all offset spitting to the end of the unit I'd like to move this code, along with all recipe contents, to blk/. It's easier if "emul-related" code is gathered at the same place.
