kernel: Interrupt waitpid (even when SIGCHLD is pending) when other signals are also pending
...
Build and test / build (push) Successful in 1m36s
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...

kernel: Rework VFS access checking + add processes
...
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...

kernel+launch: Always send SIGCHLD when a child exits
...
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.

Build and test / build (push) Successful in 1m53s
Kernel threads are supposed to use kernel_exit() instead, so it makes no sense to have an extra branch for them.
