Move NetworkOrdered.h to AK/ since it's used in both kernel and userspace.

Kernel: Introduce threads, and refactor everything in support of it.
...
The scheduler now operates on threads, rather than on processes.
Each process has a main thread, and can have any number of additional
threads. The process exits when the main thread exits.
This patch doesn't actually spawn any additional threads, it merely
does all the plumbing needed to make it possible. :^)

PNGLoader: Reduce unfiltering branchiness even more.
...
Use a dummy scanline for y=0 filled with all zeroes to avoid having to check
y on every iteration before grabbing color data from scanline[y - 1].

PNGLoader: Templatize the unfiltering functions to reduce branchiness.
...
This also allows us to dodge processing alpha values in non-alpha PNGs
without a branch.

PNGLoader: Allocate enough space for the compressed data buffer up front.
...
This is a 2x speedup on wallpaper loading.

PNGLoader: Remove a bunch of unnecessary data copying.
...
Use ByteBuffer::wrap() to avoid copying buffers around a bit. This is about
a 10% speedup on loading a wallpaper-type PNG.

SharedGraphics: Implement a simple PNG decoder.
...
This is extremely unoptimized, but it does successfully load "folder32.png"
so it must be at least somewhat correct. :^)
