continuous-integration/drone/push Build is passing
This removes a bunch of casts between pid_t and u64, and makes more sense since pid_t is literally the data type for process IDs.

continuous-integration/drone/push Build is passing
This is a more appropriate name now that it does more stuff than allocate virtual memory.
To be fair, the name was a bit awkward anyway. Should have been UserVMAllocator I guess.

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.
