Windows can now change whether they have title bar, rounded corners,
alpha channel and whether they are movable. Also windows can also change
their own position
/dev/keyboard and /dev/mouse can be read for events from any attached
keyboard or mouse respectively. This makes device hot-plugging support
pretty much automatic for TTY, GUI, and whatever takes input.
PS/2 code is now kind of messed up, but it works. Keyboards and mice are
now an abstract class that is automatically exposed to userspace. This
will make adding USB input much nicer.
userspace programs are now in userspace/programs
userspace tests are now in userspace/tests
This makes listing userspace projects much cleaner. Libraries were
already separated to their own directory, so other programs should also.
