2022-02-24many changesAda Christine
- boot time memory allocation has changed. the fractal page map has been replaced by a single self-mapped page giving 2MiB of ready virtual space to play with without needing a fully-initialized memory manager. this scheme may be repeated for other purposes - the page stack has now been totally overhauled to make use of sparse allocation and all of the ugly init_*() procedures are gone. long live the new interface. also reference counting is a thing now. sort of. - found a bug in vmt_init_node where insertion did not use the root node as the parent in the case of no predecessor node. whoops.
