Kernel: Pass process arguments directly on the stack.
...
Get rid of the convoluted get_arguments and get_environment syscalls.
This patch also adds a simple /bin/env that just prints its environment.

Kernel+Userland: Implement setuid() and setgid() and add /bin/su

Kernel: Add link() syscall to create hard links.

This accidentally grew into a little bit of VFS cleanup as well.
Also add a simple /bin/ln implementation to exercise it.

Support resizing the Terminal app.
...
I set it up so that TIOCSWINSZ on a master PTY gets forwarded to the slave.
This feels intuitively right. Terminal can then use that to inform the shell
or whoever is inside the slave that the window size has changed.
TIOCSWINSZ also triggers the generation of a SIGWINCH signal. :^)

Add ability to switch video modes from the system menu.
...
I had to change PhysicalPage around a bit for this. Physical pages can now
be instantiated for any arbitrary physical address without worrying that
such pages end up in the kernel page allocator when released.
Most of the pieces were already in place, I just glued everything together.

Move WindowServer to userspace.
...
This is a monster patch that required changing a whole bunch of things.
There are performance and stability issues all over the place, but it works.
Pretty cool, I have to admit :^)

Use modern C++ attributes instead of __attribute__ voodoo.
...
This is quite nice, although I wish [[gnu::always_inline]] implied inline.
Also "gnu::" is kind of a wart, but whatcha gonna do.

WindowServer: Begin refactoring towards a fully asynchronous protocol.
...
In order to move the WindowServer to userspace, I have to eliminate its
dependence on system call facilities. The communication channel with each
client needs to be message-based in both directions.

LibGUI: Start adding an automatic widget layout system.
...
My needs are really quite simple, so I'm just going to add what I need
as I go along. The first thing I needed was a simple box layout with
widgets being able to say whether they prefer fixed or fill for both
their vertical and horizontal sizes.
I also made a simple GStatusBar so FileManager can show how many bytes
worth of files are in the current directory.

LibC: fgetc() and pals should return EOF on error or EOF.

wrong with the pipe like I kept thinking.

Add a fast memcpy() using MMX when we're moving >= 1KB.

This is a nice speedup for WindowServer. I'll eventually have to do this
with SSE but the kernel doesn't support SSE yet so this is it for now.

Clean up LDFLAGS a bit.

While working on the ELF loader I was trying to keep binaries as simple as
possible so I could understand them easily. Now that the ELF loader is mature
and working fine, we can move closer towards ld defaults.

Kernel: Rewrite ProcFS.
...
Now the filesystem is generated on-the-fly instead of manually adding and
removing inodes as processes spawn and die.
The code is convoluted and bloated as I wrote it while sleepless. However,
it's still vastly better than the old ProcFS, so I'm committing it.
I also added /proc/PID/fd/N symlinks for each of a process's open fd's.
