Make it possible to sort a GTableModel by column+order.
...
This is accomplished by putting a GSortingProxyTableModel between the model
and the view. It's pretty simplistic but it works for this use case. :^)

Compat work towards making bash-5.0 build with less patches.
...
Hacked implementations of sigsetjmp() and siglongjmp(). I didn't know about
these APIs until just now, but I hope I got them right.

More compat work.
...
Move syscall to int 0x82 since using int 0x80 was kinda prone to fork bombs
when building things on Linux. :^)

LibC: The standard C library needs to be able to build as pure C.
...
Looks like we can't use those comfy C++ attributes in this code then.

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.

LibC: Add some things needed to build GNU bc.

This patch adds vprintf(), sig_atomic_t, random() and strdup().
bc doesn't build yet, but it will.

Add basic PTY support.
...
For now, there are four hard-coded PTYs: /dev/pt{m,s}[0123]
Use this in the Terminal to open a pty pair and spawn a shell.

Share GraphicsBitmaps between the windowing server and the client process.
...
This is pretty cool. :^)
GraphicsBitmaps are now mapped into both the server and the client address
space (usually at different addresses but that doesn't matter.)
Added a GUI syscall for getting a window's backing store, and another one
for invalidating a window so that the server redraws it.

Add some basic signal support.
...
It only works for sending a signal to a process that's in userspace code.
We implement reception by synthesizing a PUSHA+PUSHF in the receiving process
(operating on values in the TSS.)
The TSS CS:EIP is then rerouted to the signal handler and a tiny return
trampoline is constructed in a dedicated region in the receiving process.
Also hacked up /bin/kill to be able to send arbitrary signals (kill -N PID)

Enough compatibility work to make figlet build and run!
...
I ran out of steam writing library routines and imported two
BSD-licensed libc routines: sscanf() and getopt().
I will most likely rewrite them sooner or later. For now
I just wanted to see figlet running.

Canonicalize the path used by sh.

With a bunch of LibC work to support the feature. LibC now initializes
AK::StringImpl by default. It's now fine to use AK in LibC/Userland! :^)

Lots of hacking to make a very simple "ls" utility.
...
I added a dead-simple malloc that only allows allocations < 4096 bytes.
It just forwards the request to mmap() every time.
I also added simplified versions of opendir() and readdir().
