ertrie: adjusted the translation mechanisms in the tree
ertrie: added proper translation of addresses at the top level of the tree
fixed unit_posix makefile
fixed two problems
ertrie: added a prototype page-table handling file that is _untested_...wanted to push it out for feedback now.

TODO: I'm realizing that the handling of the last level (leafs within
the tree) should probably be wrapped into the main ertrie.h code as
opposed to replicated badly in each implementation.
