kernel: Make pivot_root() reset the parent entry of the new root directory ... d1ddf314d6

Otherwise it would just be pointing to the old parent fs, and we don't want that.

Almost ready for normal usage, now I just have to find out why mmap() on an ext2-loaded program crashes the entire system with a triple fault.

kernel: Separate a thread's page directory into two ... 8fc58c70f7

The self directory, and the active directory. The active directory is the one the thread is currently using,
and the self directory is the one the thread owns.

This lets us keep track of both, which fixes ext2 executables crashing the system.

We'll work out the issues booting from Ext2 later, right now it works as a mountable (but not primary) file system, and can go into main.
