This fixes init not receiving the kill signal when running tests.

kernel: Leave reaping to the reap thread
...
Build and test / build (push) Has been cancelled
This seems to fix previous problems. Apparently reaping a thread somewhat corrupts/replaces the calling thread's address space.
I should've known there's a reason we do it in a separate kernel thread...

Build and test / build (push) Has been cancelled
VFS functions now accept a single Process* pointer instead of credentials and groups.
There is now a distinction between processes and threads
Now to fix all the bugs... waitpid crashes the process with an NX error...

Build and test / build (push) Successful in 1m44s
POSIX says so. I thought it was only when the parent wasn't actively waiting, to signal it, but it turns out it's always sent.

Kernel threads are supposed to use kernel_exit() instead, so it makes no sense to have an extra branch for them.

kernel: Fix kernel panic when adding a timer before another one
...
This was caused because add_to_timer_queue() did not set active_clock when inserting a timer before the end, making disarm() a no-op.
Therefore, the clock would continue to use the timer after it had been freed.
