94ca55cefd Meta: Add license header to source files
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.

For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.

Going forward, all new source files should include a license header.

0cea80218d AK: Make it possible to store complex types in a CircularQueue
Previously we would not run destructors for items in a CircularQueue,
which would lead to memory leaks.

This patch fixes that, and also adds a basic unit test for the class.

67041f3a8c AK: Add CircularDeque.
This class inherits from CircularQueue and adds the ability dequeue
from the end of the queue using dequeue_end().

Note that I had to make some of CircularQueue's fields protected to
properly implement dequeue_end.

0dc9af5f7e Add clang-format file
Also run it across the whole tree to get everything using the One True Style.
We don't yet run this in an automated fashion as it's a little slow, but
there is a snippet to do so in makeall.sh.

b41e95b578 Snake: Use a queue for the movement inputs.
This makes it a lot less finicky to make rapid moves like staircasing and
sudden turns.

56f7b392c1 WindowServer: Move the CPU usage graph updates to a secondary thread.
This avoids blocking the main thread on filesystem access, which created
noticeable stutters during compilation.

2fb3fa7f69 WindowServer: Add a simple CPU usage graph to the global menu bar.
This is pretty cute and helps me spot when something's chewing up CPU.

7455f5ea42 Expose the kernel log buffer through /proc/dmesg.
Also add a /bin/dmesg program for convenience.

f1404aa948 Add primitive FIFO and hook it up to sys$pipe().
It's now possible to do this in bash:

cat kernel.map | fgrep List

This is very cool! :^)

fe237ee215 Lots of hacking:
- Turn Keyboard into a CharacterDevice (85,1) at /dev/keyboard.
- Implement MM::unmapRegionsForTask() and MM::unmapRegion()
- Save SS correctly on interrupt.
- Add a simple Spawn syscall for launching another process.
- Move a bunch of IO syscall debug output behind DEBUG_IO.
- Have ASSERT do a "cli" immediately when failing.
  This makes the output look proper every time.
- Implement a bunch of syscalls in LibC.
- Add a simple shell ("sh"). All it can do now is read a line
  of text from /dev/keyboard and then try launching the specified
  executable by calling spawn().

There are definitely bugs in here, but we're moving on forward.
