many changes

- 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 the fractal page map has been
  replaced by a single self-mapped page giving 2MiB of ready virtual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.
