This PR removes the CRLF characters from the message body data before
passing it to `decode_base64()` so that we can properly display the
message contents.
The :host family of pseudo class selectors select the shadow host
element when matching against a rule from within the element's shadow
tree.
This is a bit convoluted due to the fact that the document-level
StyleComputer keeps track of *all* style rules, and not just the
document-level ones.
In the future, we should refactor style storage so that shadow roots
have their own style scope, and we can simplify a lot of this.

...except for images that already use a color indexing transform
or are constant-alpha grayscale.
This makes some images larger, but it's on average better than
not doing it: When compressing all images in:
* Base/res/wallpapers
* qoi_benchmark_suite/screenshot_web
* qoi_benchmark_suite/textures_photo
...this reduces the combined output size from 105M to 88M (16%).
See PR for details on reproducing this.
(Runtime for compressing all images increases from a little under
4.4s to a little over 4.4s, so no big per cost either.)
For the images in those directories, it's even always a win.
The size of qoi_benchmark_suite/textures_pk01/pk01_floor01_local.png
increases from 366K to 375K (2.5%), so it's not _always_ a win.
Total size of qoi_benchmark_suite/textures_pk01 increases by 0.6%,
small enough that `du -sh` output is identical for that directory.

(The size of my two test gifs doesn't change, since those use the
color indexing transform.)
We used to write a color indexing transform for grayscale images.
This stores a palette and then indexes into that palette.
For grayscale images with constant alpha, we don't need to store
the palette image: Using a subtract green transform has the same effect.
(For animations, most frames don't have constant alpha because
AnimationWriter replaces identical pixels with transparent black,
making sure that these frames have a mix of opaque and transparent
pixels. But the first frame of a grayscale animation will use this.)
Only saves a couple of bytes for storing the palette image,
but it's also free in term of performance, and it's conceptually
pleasing.
Reduces the size of 7z7c.webp by 30 bytes, from 8818 to 8788 bytes.
This PR fixes a crash where the parser assumes parenthesized lists of

GCC 14 emits a warning when an always succeeding `dynamic_cast`'s return
value is compared to NULL inside the `AK::is<T>(U)` template when `T` ==

While warning on tautological `is` calls seems useful, it's a bit
awkward when it comes from a function template where the cast may fail
in some instantiation. There is a GCC bug open for it:

Previously, you'd see one frame of the sleeping animation, and then it
would stop. This was because Frame2 = 0x1 and Frame1 = 0x0, so once the
Frame2 bit was set, or-ing with Frame1 would not unset it. Since the
current frame was already tracked separately to the state, we can avoid
setting it in the state, and instead only use it when we fetch the
bitmap, preventing this issue.

We already have a FlyString of its value from parsing, and most users

The two users that did want a String are:
- Quotes, which make sense as FlyString instead, so I've converted that.
- Animation names, which should probably be FlyString too, but the code
currently also allows for other kinds of StyleValue, and I don't want
to dive into this right now to figure out if that's needed or not.

When loading a canned version of reddit.com, we end up parsing many many
shadow tree style sheets of roughly ~170 KiB text each.
None of them have '\r' or '\f', yet we spend 2-3 ms for each sheet just
looping over and reconstructing the text to see if we need to normalize
any newlines.
This patch makes the common case faster in two ways:
- We use TextCodec::Decoder::to_utf8() instead of process()
This way, we do a one-shot fast validation and conversion to UTF-8,
instead of using the generic code-point-at-a-time callback API.
- We scan for '\r' and '\f' before filtering, and if neither is present,
we simply use the unfiltered string.
With these changes, we now spend 0 ms in the filtering function for the
vast majority of style sheets I've seen so far.

The LibELF validate_program_headers method tried to do too many things
at once, and as a result, we had an awkward return type from it.
To be able to simplify it, we no longer allow passing a StringBuilder*
but instead we require to pass an Optional<Elf_Phdr> by reference so
it could be filled with actual ELF program header that corresponds to
an INTERP header if such found.
As a result, we ensure that only certain implementations that actually
care about the ELF interpreter path will actually try to load it on
their own and if they fail, they can have better diagnostics for an
invalid INTERP header.
This change also fixes a bug that on which we failed to execute an ELF
program if the INTERP header is located outside the first 4KiB page of
the ELF file, as the kernel previously didn't have support for looking
beyond that for that header.
Together with a first JSON file for bringing up a fully functional
BuggieBox container, we allow users to take advantage of the kernel
unsharing features that were introduced in earlier commits.
This new syscall will be used by the upcoming runc (run-container)
utility.
In addition to that, this syscall allows userspace to neatly copy RAMFS
instances to other places, which was not possible in the past.
These programs are capable of running other programs, so we should
restrict them from potentially running SUID programs, which was never a
functionality we supported for those programs anyway.
The whole concept of Jails was far more complicated than I actually want
it to be, so let's reduce the complexity of how it works from now on.
Please note that we always leaked the attach count of a Jail object in
the fork syscall if it failed midway.
Instead, we should have attach to the jail just before registering the
new Process, so we don't need to worry about unsuccessful Process
creation.
The reduction of complexity in regard to jails means that instead of
relying on jails to provide PID isolation, we could simplify the whole
idea of them to be a simple SetOnce, and let the ProcessList (now called
ScopedProcessList) to be responsible for this type of isolation.
Therefore, we apply the following changes to do so:
- We make the Jail concept no longer a class of its own. Instead, we
simplify the idea of being jailed to a simple ProtectedValues boolean
flag. This means that we no longer check of matching jail pointers
anywhere in the Kernel code.
To set a process as jailed, a new prctl option was added to set a
Kernel SetOnce boolean flag (so it cannot change ever again).
- We provide Process & Thread methods to iterate over process lists.
A process can either iterate on the global process list, or if it's
attached to a scoped process list, then only over that list.
This essentially replaces the need of checking the Jail pointer of a
process when iterating over process lists.
Expose some initial interfaces in the mount-related syscalls to select
the desired VFSRootContext, by specifying the VFSRootContext index

for the first userspace VFSRootContext.
Negative numbers now display correctly in SpinBox.

Lossless WebP allows having a 1-bit to 11-bit addressed
"color cache", where pixels are inserted into a content-addressed
cache of size `1 << color_cache_bits`. Pixels in the color
cache can be addressed using their index. This can be used
to refer to literal pixels using a single color_cache_bits
large symbol, instead of up to 4 symbols for GBRA.
We default to always using a color cache with 6 bits, unless
the input image already uses only a single channel already
(either as-is, or if we write a color indexing transform).
Due to this change, the size of the first prefix group
changes from being known at compile time (256 + 24)
to being known at runtime (256 + 24 + color_cache_size).
Change a few Array<>s to Vector<>s to make this work.
