Add a /dev/pts filesystem and make PTY allocation dynamic.
...
You can now open as many PTY pairs as you like. Well, it's actually capped
at 8 for now, but it's just a constant and trivial to change.
Unregistering a PTY pair is untested because I didn't want to start
mucking with that in Terminal right now.

PTY: Disallow infinite writing to slaves.
...
This way we don't buffer ungodly amounts of output in the kernel when doing
e.g "cat /dev/random" on a PTY.

Add basic PTY support.
...
For now, there are four hard-coded PTYs: /dev/pt{m,s}[0123]
Use this in the Terminal to open a pty pair and spawn a shell.
