Make it possible for a process to switch controlling terminals.
...
Via the TIOCSCTTY and TIOCNOTTY ioctls.

Start refactoring the windowing system to use an event loop.
...
Userspace programs can now open /dev/gui_events and read a stream of GUI_Event
structs one at a time.
I was stuck on a stupid problem where we'd reenter Scheduler::yield() due to
having one of the has_data_available_for_reading() implementations using locks.

TTY::write() should return the number of bytes written.

VirtualConsole: Support the 'A' and 'D' CSI sequences.
...
This makes backspace work correctly when line editing with bash-2.05b.

Make it possible to build the Kernel on a macOS host.
...
It still requires an ELF compiler and linker, but at least it builds.
I need to get rid of the "Unix" namespace. This does a lot of that.

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".

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().

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 :^)
