Fixed lots of issues with mm0 initialization, final one was an oversized do_munmap.

test0 now successfully runs its beginning.
test0 SConscript has a dependency problem.

Issues to be investigated:
- vm_file and vnodes need to be merged fully in all functions.
- libposix shared page references need to be removed.
- Any references to VFS_TID, PAGER_TID need to be removed.
