kernel now passes the name of default console to init process so init
knows which file to open as stdio. before /dev/tty was referencing the
system wide current terminal which was inherited from cmdline. This
doesn't work anymore as we have pseudo terminals implemented that can
chage the current terminal during runtime :D
userspace programs are now in userspace/programs
userspace tests are now in userspace/tests
This makes listing userspace projects much cleaner. Libraries were
already separated to their own directory, so other programs should also.
