Subject: kernel: rework /proc/ and process IDs

I'm yet to write proper docs but the TL;DR is:

Mounting /proc/ creates a new pid namespace. You're still visible in the old
namespace with your old pid, but your children won't be. You see your own pid
as 1. Current pids of children will be preserved, pids will be allocated starting
from the highest one of your children.
