AK: Make min/max behave like the STL for equivalent inputs (#2976) 
min(a, b) now returns a if both are equivalent.
max(a, b) now returns a if both are equivalent.

ce2c5b375c AK: Add global is<T>() and downcast<T>() 
Let's unify the is<T>/to<T> implementations that currently exist in
separate versions in LibCore and LibWeb.

70cb4491d7 AK: Use "signed char" as the opposite of "unsigned char" 
I totally forgot about the C++ basics here. There are three distinct
types: "char", "signed char" and "unsigned char". Whether "char" is
signed or unsigned is implementation specific.

f8942411ac AK: Add forward() overload that refuses to forward lvalue as rvalue 
This matches what other forward() implementations do.

900f51ccd0 AK: Move memory stuff (fast memcpy, etc) to a separate header 
Move the "fast memcpy" stuff out of StdLibExtras.h and into Memory.h.
This will break a ton of things that were relying on StdLibExtras.h
to include a bunch of other headers. Fix will follow immediately after.

This makes it possible to include StdLibExtras.h from Types.h, which is
the main point of this exercise.

b98d8ad5b0 AK: Add a Conditional<condition, TrueType, FalseType> template 
This allows you to select a type based on a compile-time condition.

de74458f13 AK: Add clamp() function 
This function can be used to more cleanly write the common operation of
clamping a value between two values.

94ca55cefd Meta: Add license header to source files 
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.

For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.

Going forward, all new source files should include a license header.

57c29491a3 Kernel+AK: Remove AK/StdLibExtras.cpp, moving kernel stuff to Kernel/. 
We had some kernel-specific gizmos in AK that should really just be in the
Kernel subdirectory instead. The only thing remaining after moving those
was mmx_memcpy() which I moved to the ARCH(i386)-specific section of
LibC/string.cpp.

27f699ef0c AK: Rename the common integer typedefs to make it obvious what they are. 
These types can be picked up by including <AK/Types.h>:

* u8, u16, u32, u64 (unsigned)
* i8, i16, i32, i64 (signed)

0dc9af5f7e Add clang-format file 
Also run it across the whole tree to get everything using the One True Style.
We don't yet run this in an automated fashion as it's a little slow, but
there is a snippet to do so in makeall.sh.

cec16105cc Make sure all GraphicsBitmap scanlines are 16-byte aligned. 
This is a prerequisite for some optimizations.

6693cfb26a Kernel: Don't use MMX memcpy() in the kernel. 
I just discovered the hard way that clobbering FPU/MMX/SSE registers in the
kernel makes things very confusing for userspace (and other kernel threads.)

Let's banish all of those things from the kernel to keep things simple.

301a269ca0 Get rid of SERENITY macro since the compiler already defines __serenity__ 
This makes it a bit easier to use AK templates out-of-tree.

47d270b577 WindowServer: Factor out window frame logic into a WSWindowFrame class. 
The window frame is an object that contains a window, its title bar and
window border. This way WSWindowManager doesn't have to know about all the
different types of window borders, titlebar rects, etc.

2cfcbdc735 AK: Add Retained<T>, like RetainPtr, but never null. 
Also use some Clang attribute wizardry to get a warning for use-after-move.

022f7790db 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.

1f159eaab0 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.
