0ebaa35aa1 Kernel: Let the process argv arrays be null-terminated.
Seems like this is expected. I don't know why I thought it wasn't.

8bb18fdc56 Kernel: Get rid of Unix namespace.
This is no longer needed as the Kernel can stand on its own legs now
and there won't be any conflict with host system data types.

e911caeb10 Kernel: Fix dumb race in Scheduler::yield() debug code.
It was perfectly possible for Scheduler::yield() to get interrupted after
setting s_in_yield but before disabling interrupts.

07f4c8b01b VFS: Get rid of the deprecated Inode::write(const ByteBuffer&).
Fix the only remaining call site to use Inode::write_bytes().

906685e238 Ext2FS: Implement writing into inodes with arbitrary offset and length.
Okay, this is pretty cool. :^) There are some issues and limitations for
sure but the basic functionality is there.

bda0c935c2 Add unlink() syscall and /bin/rm.
This patch adds most of the plumbing for working file deletion in Ext2FS.
Directory entries are removed and inode link counts updated.
We don't yet update the inode or block bitmaps, I will do that separately.

2f2f28f212 Kernel: Refactor Region/PageDirectory ownership model.
Make PageDirectory retainable and have each Region co-own the PageDirectory
they're mapped into. When unmapped, Region has no associated PageDirectory.

This allows Region to automatically unmap itself when destroyed.

afccbe51a4 VFS: Place new files in the correct subdirectory.
Oops, every new file was ending up in the root directory.
Also make sure we create the inode in the same FS as the parent directory.

f70136a324 Kernel: Support open() with O_CREAT.
It's now possible to create zero-length files! :^)
Also hook up the new functionality in /bin/touch.

51595603bd WindowServer: Rename WSEvent subclasses WSFooEvent for consistency.
Add a WSWindowInvalidationEvent that carries a rect instead of having an
awkward single-purpose rect in WSEvent.
Flesh out WSKeyEvent a bit more.

76a2881793 Mark the two Regions used GraphicsBitmaps as explicitly shared.
This fixes a goofy problem where forking a GUI process would cowify the
GraphicsBitmap for everyone making a hue confusing mess.

291922b1af WindowServer: Show PID and window ID in title bars for now.
This is useful for debugging since I'm often wondering which process some
window belongs to (and what the window ID is.)

3271c115e2 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.

a9e60fc800 LibGUI: Only redraw the dirty rect in GWidget.
There is some trouble here with the asynchronous nature of WindowServer
and the single per-window backing store we're drawing into. If we start
repainting a widget with a pending invalidation, that invalidation might
get flushed by the WindowServer mid-paint.

dbe83f3a83 Make it possible for userspace to alter window title/geometry.
I'm not in love with this syscall API but it allows me to make progress.
