Kernel: Make the x86 paging code slightly less insane.
Instead of PDE's and PTE's being weird wrappers around dword*, just have MemoryManager::ensure_pte() return a PageDirectoryEntry&, which in turn has a PageTableEntry* entries(). I've been trying to understand how things ended up this way, and I suspect it was because I inadvertently invoked the PageDirectoryEntry copy ctor in the original work on this, which must have made me very confused.. Anyways, now things are a bit saner and we can move forward towards a better future, etc. :^)
