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.

6f74c1bb11 AK: Allow to "get a result" from Result<void>
This is to make Result<void> work inside TRY

56a6d7924e AK: Let Result<T, E> know its Value and Error types
It's much easier to ask for T::ValueType than for
RemoveReference<decltype(declval<T>().release_value())>

1682f0b760 Everything: Move to SPDX license identifiers in all files.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

See: https://spdx.dev/resources/use/#identifiers

This was done with the `ambr` search and replace tool.

AK: Fix bogus return type of Result::release_error() (#6054)
The function was not used anywhere so the error was unnoticed.

4a83a37f79 AK: Add release_value() and release_error() to AK::Result
These are nice when you want to move something out of the result,
and match the API we already have for Optional.

986544600a AK: Add Result<void, ErrorType> specialization, cleanup
Add a specialization for a void ValueType. This is useful if a generic
function wants to return a Result<T, E> where the user might not
actually care abut the T, and default it to void. In this case it
basically becomes Unexpected<E> instead of Result, but hey, it works :)

bbe787a0af Everywhere: Re-format with clang-format-11
Compared to version 10 this fixes a bunch of formatting issues, mostly
around structs/classes with attributes like [[gnu::packed]], and
incorrect insertion of spaces in parameter types ("T &"/"T &&").
I also removed a bunch of // clang-format off/on and FIXME comments that
are no longer relevant - on the other hand it tried to destroy a couple of
neatly formatted comments, so I had to add some as well.

ba3b561a40 AK: Simplify Result class so we can start using it
There were some ideas about how to use this class but we never actually
started using it, so let's just simplify it and get it ready for use.

The basic idea is: a function returns a Result<ValueType, ErrorType>.
Callers check if the result object is_error(). If so, an ErrorType can
be fetched with the error() getter. Otherwise, a ValueType is fetched
with the value() getter. That's it. :^)

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.

a82c60b22a Add Result<>, to use with/complement Error
An operation often has two pieces of underlying information:

* the data returned as a result from that operation
* an error that occurred while retrieving that data

Merely returning the data is not good enough. Result<> allows exposing
both the data, and the underlying error, and forces (via clang's
consumable attribute) you to check for the error before you try to
access the data.
