Using the walk_device_tree helper, we can walk the device tree from the
beginning looking for a specific property node. It's still missing the
ability to get property lists, string lists, and property-specific data.

ReadonlyBytes is much nicer to use than a u8 const* + size_t.

Previously, we only saved the REPL history when the interpreter was
shutdown with a signal. This change ensures that we save the history
when a user uses `exit()`.
|
|
The patch also contains modifications on several classes, functions or
files that are related to the `JPGLoader`.
Renaming include:
- JPGLoader{.h, .cpp}
- JPGImageDecoderPlugin
- JPGLoadingContext
- JPG_DEBUG
- decode_jpg
- FuzzJPGLoader.cpp
- Few string literals or texts

This adds three flags to icc:
* --reencode-to=<file> re-serializes a profile to a given file,
using Gfx::ICC::encode(). This is mainly useful for testing that
code.
* --dump-to=<file> dumps the raw ICC profile bytes read from the
input to disk. This is useful for extracting ICC profiles from
images, and for comparing the raw profile bytes to the profile
bytes written by --reencode-to=.
If either of these flags is passed, icc by default no longer dumps
the icc data to stdout. To force priting of the data even if either
of these flags is present, this also adds:
* --print, which forces printing ICC contents, even if either or
both of the icc-data writing flags are present.

This includes an Error::create overload to create an Error from a UTF-8
StringView. If creating a String from that view fails, the factory will
return an OOM InternalError instead. VM::throw_completion can also make
use of this overload via its perfect forwarding.

We don't need a full String/DeprecatedString inside this function, so we
might as well not force users to create one.

As usual, this removes many unused includes and moves used includes
further down the chain.

It's not needed in such case, and in the near-future when we would want
to use this utility in an initramfs environment where there's no service
such as LookupServer being running, it's still useful to have the option
to invoke this utility with the mentioned limited output functionality.

This isn't terribly useful. But some profiles, for example the ones at
https://vpifg.com/help/icc-profiles/, do contain this tag and it seems
nice to be able to dump it, just for completeness.
I haven't seen any files that contain a phosphor or colorant type
different from "Unknown", even for the Rec2020 profile on that page.
(It has x,y coordinates that match the values required for Rec2020,
but it doesn't set the phosphor or colorant type to that.)

Not terribly useful in practice either and also mostly for
completionism. But with this, we can dump all types present
in Lightroom Classic-exported jpegs :^)

Also not terribly useful in practice and mostly for completionism.
Lightroom Classic-exported jpegs contain this type in their ICC data.

For example, consider cases where we want to propagate errors only in
specific instances:
auto result = read_data(); // something like ErrorOr<ByteBuffer>
if (result.is_error() && result.error().code() != EINTR)
continue;
auto bytes = TRY(result);
The TRY invocation will currently copy the byte buffer when the
expression (in this case, just a local variable) is stored into
_temporary_result.
This patch binds the expression to a reference to prevent such copies.
In less trival invocations (such as TRY(some_function()), this will
incur only temporary lifetime extensions, i.e. no functional change.

Either take the underlying objects with release_* methods or move() the
instances around.

These are among the permitted tag types of ATo0Tag and BToA0Tag,
which are among the required tags of most profiles. They are the
last permitted tag types for those profiles (the other are
lut8Type or lut16Type, which are already implemented).
They are pretty chonky types though, so this only implements
support for the E matrix and the CLUT. Support for the various
curves will be in a future PR.

This is a very new tag used for HDR content. The only files I know that
use it are the jpegs on https://ccameron-chromium.github.io/hdr-jpeg/
But they have an invalid ICC creation date, so `icc` can't process them.
(Commenting out the check for that does allow to print them.)
If the CIPC tag is present, it takes precedence about the actual data
in the profile and from what I understand, the ICC profile is
basically ignored. See https://www.color.org/events/HDR_experts.xalter
for background, in particular
https://www.color.org/hdr/02-Luke_Wallis.pdf (but the other talks
are very interesting too).
(PNG also has a cICP chunk that's supposed to take precedence over
iCCP.)

This isn't used by any mandatory tags, and it's not terribly useful.
But jpegs exported by Lightroom Classic write the 'tech' tag, and
it seems nice to be able to dump its contents.
signatureType stores a single u32 which for different tags with this
type means different things.
In each case, the value is one from a short table of valid values,
suggesting this should be a per-tag enum class instead of a
per-tag DistinctFourCC, per the comment at the top of DistincFourCC.h.
On the other hand, 3 of the 4 tables have an explicit "It is possible
that the ICC will define other signature values in the future" note,
which suggests the FourCC might actually be the way to go.
For now, just punt on that and manually dump the u32 in fourcc style
in icc.cpp and don't add any to_string() methods that return a readable
string based on the contents of these tables.

This is the type of namedColor2Tag, which is a required tag in
NamedColor profiles.
The implementation is pretty basic for now and only exposes the
numbers stored in the file directly (after endian conversion).

Before 6490529ef76ebf37f9e58bf76c6271be6842afa1, all programs in the
SPECIAL_TARGETS list were built because they didn't have an
EXCLUDE_FROM_ALL property set.
That commit set the property for all targets, but because of this, the
minimal "Required" build configuration no longer built, as CMake failed
to rename every special target. Even the not built ones.
This commit makes the rename action run only if the executable exists,
which makes us build Serenity without the `install` utility, and also
by using the minimal configuration set. :^) :^)

SQLClient exists as a wrapper around SQL IPC to provide a bit friendlier
interface for clients to deal with. Though right now, it mostly forwards
values as-is from IPC to the clients. This makes it a bit verbose to add
values to IPC responses, as we then have to add it to the callbacks used
by all clients. It's also a bit confusing seeing a sea of "auto" as the
parameter types for these callbacks.
This patch moves these response values to named structures instead. This
will allow adding values without needing to simultaneously update all
clients. We can then separately handle the new values in interested
clients only.

It also adds support for `ErrorOr` in one lambda.
