7bdf54c837 Kernel: PID/PGID typing 
This compiles, and fixes two bugs:
- setpgid() confusion (see previous commit)
- tcsetpgrp() now allows to set a non-empty process group even if
  the group leader has already died. This makes Serenity slightly
  more POSIX-compatible.

f5744a6f2f Kernel: PID/TID typing 
This compiles, and contains exactly the same bugs as before.
The regex 'FIXME: PID/' should reveal all markers that I left behind, including:
- Incomplete conversion
- Issues or things that look fishy
- Actual bugs that will go wrong during runtime

30b2c0dc85 Kernel: Use Userspace<T> for the getsockopt syscall and Socket interface 
The way getsockopt is implemented for socket types requires us to push
down Userspace<T> using into those interfaces. This change does so, and
utilizes proper copy implementations instead of the kind of haphazard
pointer dereferencing that was occurring there before.

ddab7ab693 Kernel: Store TTY's foreground process as a WeakPtr<Process> 
This ensures that we don't leave a stale PGID assigned to the TTY after
the process exits, which would make PID recycling attacks possible.

7e6fbef8db Kernel: Partial usage of Userspace<T> for the poll syscall 
This change mostly converts poll to Userspace<T> with the caveat
of the fds member of SC_poll_params. It's current usage is a bit
too gnarly for me to take on right now, this appears to need a lot
more love.

In addition to enlightening the syscall to use Userspace<T>, I've
also re-worked most of the handling to use validate_read_and_copy
instead of just directly de-referencing the user pointer. We also
appeared to be missing a re-evaluation of the fds array after the
thread block is awoken.

fa666f6897 Kernel: Use Userspace<T> for the futex syscall 
Utilizie Userspace<T> for the syscall argument itself, as well
as internally in the SC_futex_params struct.

We were double validating the SC_futex_params.timeout validation,
that was removed as well.
