kernel: Zero physical frames instead of virtual pages
...
continuous-integration/drone/push Build is passing

kernel: Separate a thread's page directory into two
...
continuous-integration/drone/pr Build is passing
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.

This can cover the entire address space at once in a more memory-efficient way.
Stress-tested using 'base64 /bin/ls' which allocates enough contiguous
virtual memory to store the entirety of /bin/ls :)
