Kernel: Move errno.h and (k)assert.h out of the main include directory
...
This is mostly so IDEs don't pick them up instead of the userspace headers :)

Kernel, libc: Implement waitpid()
...
FIXME: exec() is now doing weird page table stuff. But at least it works, no panics :)

Kernel: Rename the getpid() syscall to getprocid()
...
Now, we have one single system call to fetch all sorts of identifiers:
PID, PPID, UID, GID; EUID, EGID, and more...

Kernel, libc: Add support for providing a status code to exit()
...
The exit() libc function already accepted an integer, but didn't pass it on to the kernel since we had no mechanism for it to do that.
Now, the kernel stores a task's exit status to display it later (and in the future, return it to userspace via wait()/waitpid())
