ac7a60225e Add TIOCGWINSZ ioctl so userland can determine terminal geometry.
(Don't) use this to implement short-form output in ls.
I'm too tired to make a nice column formatting algorithm.
I just wanted something concise when I type "ls".

a788e85c09 Refactor TTY signal generation a bit.
We now respect the VINTR and VQUIT control characters in the termios.

d2046e79cf Add a DoubleBuffer thingy to allow TTY read/write to be interleaved.
I feel like this concept might be useful in more places. It's very naive
right now and uses dynamically growing buffers. It should really use static
size buffers and never kmalloc().

da3857b0c2 Add some simple write buffering to LibC's stdio.
Plumb it all the way to the VirtualConsole. Also fix /bin/cat to write()
the whole chunks we get from read() directly to stdout.

10b666f69a Basic ^C interrupt implementation.
For testing, I made cat put itself into a new process group.
This should eventually be done by sh between fork() and exec().

7a7956a595 Virtual consoles kinda work!
We now make three VirtualConsoles at boot: tty0, tty1, and tty2.
We launch an instance of /bin/sh in each one.
You switch between them with Alt+1/2/3

How very very cool :^)

68739dc43e Start working on virtual consoles/TTYs.
This is a mess right now, but I'd rather commit as I go.
