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".

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

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().

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.

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().

Add tcsetpgrp()+tcgetpgrp().
...
One more step on the path to being able to ^C a runaway process. :^)

Add sys$ttyname_r and ttyname_r() + ttyname().
...
And print a greeting when sh starts up so we know which TTY we're on.

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 :^)

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