Kernel: Add a pstat() system call
...
Not part of C or POSIX, but since there is no procfs right now, I thought it would be nice to have an interface to query process information.
It works like this: you pass the process ID and a pointer to a struct pstat (can be null).
If the process ID is -1, the kernel picks the process with the highest PID.
Then, if the pointer to a pstat struct is not null, the kernel fills it in with the process's information, and returns the process's PID.

This is bad design. But it fails if mapped, since something overwrites KernelHeap.
