d06057f88b AK: Don't refer to AK::swap() as ::swap()
While swap() is available in the global namespace in normal conditions,
!USING_AK_GLOBALLY will make this name unavailable in the global
namespace, making these calls fail to compile.

ae3ffdd521 AK: Make it possible to not using AK classes into the global namespace
This patch adds the `USING_AK_GLOBALLY` macro which is enabled by
default, but can be overridden by build flags.

This is a step towards integrating Jakt and AK types.

f03f70a84a AK: Make empty FixedArray smaller
Move the FixedArray's size field into the heap-allocated storage. This
makes zero-sized FixedArrays take up 8 bytes instead of 16.

65f34504e9 AK: Add FixedArray::is_empty()
This also exists on Vector, and although it's less needed here, it's
perfectly reasonable to have.

64778f9e69 AK: Add a constructor from Span for FixedArray
This is particularly useful in the Kernel, where the physical pages of
a VMObject are stored as a FixedArray but often passed around as a Span
from which a new FixedArray should be cloned.

0362b15895 AK: Add a constructor from C-style arrays for FixedArray
We really want to be able to construct FixedArray from a list of
non-copyable but movable objects. This constructor is useful for
such things.

1d144ed6fc AK: Remove clear() from FixedArray and fixate its allocation guarantees
FixedArray always *almost* had the following allocation guarantees:
There is (possibly) one allocation in the constructor and one (or more)
deallocation(s) in the destructor. No other operation allocates or
deallocates. With this removal of the public clear() method, which
nobody except the test used anyways, those guarantees are now completely
true and furthermore fixated with an explanatory comment.

3c05261611 AK+Everywhere: Make FixedArray OOM-safe
FixedArray now doesn't expose any infallible constructors anymore.
Rather, it exposes fallible methods. Therefore, it can be used for
OOM-safe code.
This commit also converts the rest of the system to use the new API.
However, as an example, VMObject can't take advantage of this yet,
as we would have to endow VMObject with a fallible static
construction method, which would require a very fundamental change
to VMObject's whole inheritance hierarchy.

88c8451973 AK: Bring back FixedArray<T>
Let's bring this class back, but without the confusing resize() API.
A FixedArray<T> is simply a fixed-size array of T.

The size is provided at run-time, unlike Array<T> where the size is
provided at compile-time.

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.

5096eaa845 AK: Add a FixedArray<T> container
This is a simple array wrapper that knows its size. It has begin/end
so you can use range-for. It also has a resize() that reallocates.
