2b866e3c9b LibGfx: Remove ImageDecoderPlugin::bitmap() in favor of frame(index)
To encourage proper support for multi-frame images throughout the
system, get rid of the single-frame convenience bitmap() API.

20163c0584 LibJS: Add ThrowCompletionOr versions of the JS native function macros
The old versions were renamed to JS_DECLARE_OLD_NATIVE_FUNCTION and
JS_DEFINE_OLD_NATIVE_FUNCTION, and will be eventually removed once all
native functions were converted to the new format.

4d8912a92b LibJS: Convert to_string() to ThrowCompletionOr
Also update get_function_name() to use ThrowCompletionOr, but this is
not a standard AO and should be refactored out of existence eventually.

c06a0bae04 Meta: Fix broken external links
Meta/Lagom/ReadMe.md never had any other name; not sure how that typo
happened.

The link to the non-existent directory is especially vexing because the
text goes on to explain that we don't want such a directory to exist.

Found by running markdown-checker, and 'wget'ing all external links.

b6e5117f65 Lagom: Change to shared library build for all Lagom code
Split the Lagom build into shared libraries to match the Serenity build.

This reduces the cognitive load when trying to edit the Lagom CMakeLists
significantly. It also reduces the amount of source files that must be
compiled to run each test or host program significantly.

Also re-organize all the build rules into sections. And reorganize the
CMakeLists file in general.

af9be6e093 LibTTF/LibGfx: Remove circular dependency by merging LibTTF into LibGfx
LibTTF has a concrete dependency on LibGfx for things like Gfx::Bitmap,
and LibGfx has a concrete dependency in the TTF::Font class in
Gfx::FontDatabase. This circular dependency works fine for Serenity and
Lagom Linux builds of the two libraries. It also works fine for static
library builds on Lagom macOS builds.

However, future changes will make Lagom use shared libraries, and
circular library dependencies are not tolerated in macOS.

53f70e5208 LibJS: Remove the default length & attributes from define_native_*
These are usually incorrect, and people sometimes forget to add the
correct values as a result of them being optional, so they should just
be specified explicitly.

49d0b9e808 LibTTF: Memory map TTF fonts instead of reading them into heap memory
All GUI applications currently load all TTF fonts on startup
(to populate the Gfx::FontDatabase. This could probably be smarter.)

Before this patch, everyone would open the files and read them into
heap-allocated storage. Now we simply mmap() them instead. :^)

51c2c69357 AK+Everywhere: Disallow constructing Functions from incompatible types
Previously, AK::Function would accept _any_ callable type, and try to
call it when called, first with the given set of arguments, then with
zero arguments, and if all of those failed, it would simply not call the
function and **return a value-constructed Out type**.
This lead to many, many, many hard to debug situations when someone
forgot a `const` in their lambda argument types, and many cases of
people taking zero arguments in their lambdas to ignore them.
This commit reworks the Function interface to not include any such
surprising behaviour, if your function instance is not callable with
the declared argument set of the Function, it can simply not be
assigned to that Function instance, end of story.

5f18cf75c5 AK: Replace ByteBuffer::grow with resize()/ensure_capacity()
Previously ByteBuffer::grow() behaved like Vector<T>::resize().
However the function name was somewhat ambiguous - and so this patch
updates ByteBuffer to behave more like Vector<T> by replacing grow()
with resize() and adding an ensure_capacity() method.

This also lets the user change the buffer's capacity without affecting
the size which was not previously possible.

Additionally this patch makes the capacity() method public (again).

dd633b9dd1 Meta: Fix Fuzzers CMakeLists.txt and ReadMe.md to use CXX_COMPILER_ID
Previously the directions omitted that you have to specify
`-CMAKE_CXX_COMPILER` when building the Fuzzers. This
would cause all kinds of weird problems at compilation and
link time. You can't specify one or the other, they must
both be pointing at clang in order for things to work as
experted. Fix this by updating the documentation to specify
that the user should specify both the C and CXX compiler explicitly
to be safe, as well as forcing the cmake clang argument handling
to modify the CXX compiler variable instead of the C version.

e265054c12 Everywhere: Remove a bunch of redundant 'AK::' namespace prefixes
This is basically just for consistency, it's quite strange to see
multiple AK container types next to each other, some with and some
without the namespace prefix - we're 'using AK::Foo;' a lot and should
leverage that. :^)

5d180d1f99 Everywhere: Rename ASSERT => VERIFY
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)

Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.

c6a42ab5c3 Everywhere: Remove unnecessary headers 4/4
Arbitrarily split up to make git bisect easier.

These unnecessary #include's were found by combining an automated tool (which
determined likely candidates) and some brain power (which decided whether
the #include is also semantically superfluous).
