Let userland retain the window backing store while drawing into it.
...
To start painting, call:
gui$get_window_backing_store()
Then finish up with:
gui$release_window_backing_store()
Process will retain the underlying GraphicsBitmap behind the scenes.
This fixes racing between the WindowServer and GUI clients.
This patch also adds a WSWindowLocker that is exactly what it sounds like.

WindowServer: Only blit dirty rect of windows to back buffer.
...
Previously we'd blit every pixel in every window that intersected any dirty
rect to the back buffer. With this patch, we limit ourselves to blitting the
pixels inside the actual dirty rects.
There's still a lot of optimizations to make in this code.

Add a PTY multiplexer (/dev/ptmx) device.
...
When you open /dev/ptmx, you get a file descriptor pointing to one of the
available MasterPTY's. If none are available, you get an EBUSY.
This makes it possible to open multiple (up to 4) Terminals. :^)
To support this, I also added a CharacterDevice::open() that gets control
when VFS is opening a CharacterDevice. This is useful when we want to return
a custom FileDescriptor like we do here.

Get rid of Vnode concept.

We already have an abstraction between Process and Inode/CharacterDevice/FIFO
and it's called FileDescriptor. :^)

Terminal: optimize repaints a bunch.

We track dirty character cells + pending whole-terminal scrolls.
This drastically reduces the number of pixels pushed.
