There are three compiler bugs that influence this decision:
- Clang writing to (validly) destroyed coroutine frame with -O0 and
-fsanitize=null,address under some conditions
(https://godbolt.org/z/17Efq5Ma5) (AK_COROUTINE_DESTRUCTION_BROKEN);
- GCC being unable to handle statement expressions in coroutines
(AK_COROUTINE_STATEMENT_EXPRS_BROKEN);
- GCC being unable to deduce template type parameter for TryAwaiter
with nested CO_TRYs (AK_COROUTINE_TYPE_DEDUCTION_BROKEN).
Instead of growing an ifdef soup in AK/Coroutine.h and
LibTest/AsyncTestCase.h, define three macros in AK/Platform.h that
correspond to these bugs and use them accordingly in the said files.
In case the user requests this, init can drop directly to a shell
without trying to spawn SystemServer.
To test this on x86-64, run:
```
Meta/serenity.sh run x86_64 GNU "init_args=emergency"
```
Also, init will drop to emergency shell if mounting filesystems with
`mount -a` failed for some reason.
This functionality can be useful in many cases.
For example, if the user needs to perform a command that must not alter
a corrupted filesystem state, then this mode is useful as the filesystem
should be mounted in read-only mode.
Another example is the ability to get a functioning system in case
SystemServer behaves badly or inconsistently, or the user specified a
wrong fstab entry, so proceeding to boot is probably a bad option.
Let's make SystemServer simpler by not involving it with the basic
system initialization sequence.
That initialization sequence can be done in another program that
theoretically can be put in another filesystem.

If the user only wants to get the byte count of a set of files, then for
each file we can simply seek it to get the byte count instead of
iterating over all the bytes.
This is done by using a FixedStringBuffer as the foundation to perform
string formatting, which ensures that we avoid memory allocations in
the prekernel stage.
These methods do basically nothing right now, because we don't allocate
memory in the prekernel stage.
It's only here for a later commit when we bring up assertion formatting
and printing.
With this change, we no longer preallocate blocks when an inode's size
is updated, and instead only allocate the minimum amount of blocks when
the inode is actually written to.
This is a large commit, since this is essentially a complete rewrite of
the key low-level functions that handle reading/writing blocks. This is,
however, a necessary prerequisite of being able to write holes.
The previous version of `flush_block_list()` (along with its numerous
helper functions) was entirely reliant on all blocks being sequential.
In contrast to the previous implementation, the new version
of `flush_block_list()` simply writes out the difference between the old
block list and the new block list by calculating the correct indirect
block(s) to update based on the relevant block's logical index.
`compute_block_list()` has also been rewritten, since the estimated
amount of meta blocks was incorrectly calculated for files with holes as
a result of the estimated amount of blocks being a function of the file
size. Since it isn't possible to accurately compute the shape of the
block list without traversing it, we no longer try to perform such a
computation, and instead simply search through all of the allocated
indirect blocks.
`compute_block_list_with_meta_blocks()` has also been removed in favor
of the new `compute_meta_blocks()`, since meta blocks are fundamentally
distinct from data blocks due to there being no mapping between any
logical block index and the physical block index.
Since we now only store blocks that are actually allocated, it is
entirely valid for the block list to be empty, so this commit lifts the
restrictions on accessing inodes with an empty block list.
- Document exactly which crash features are available on which
architectures. There's several interesting crash tests we will want to
add for specific architectures, such as misaligned memory accesses.
- Don't compile the divide by zero crash test on RISC-V, as they simply
don't crash here.
- Rename the test for "x86 User Mode Instruction Prevention" to a more
generic "try to execute a priviledged instruction"; whatever that
specifically entails on any given architecture.
- Rename a bunch of internal variables to more generic names.
- Wrap the x86-specific implementation of "execute non executable
memory" in architecture preprocessor checks.
Both Element's and ShadowRoot's setHTMLUnsafe, and Document's static
parseHTMLUnsafe methods are implemented.

Dialog elements now correctly establish a close watcher when
shown modally.
This means modal dialogs now correctly close with an escape key press.

No other browser allows opening the select element dropdown with the
select.click() function.
This change stops this happening in Ladybird.

Similarly to OpenBSD nc, an option to just connect without transmitting
any actual data is added.
However, we don't allow UDP-mode when testing a remote service, as it
will always succeed and has no technical meaning for the user if they're
not able to view the traffic on the remote machine.
Adds the showPicker() function for select elements.
This doesn't do the check for "being rendered" which is in the spec.

This implements most of the CloseWatcher API from the html spec.
AbortSignal support is unimplemented.
Integration with dialogs and popovers is also unimplemented.

the second commit of https://github.com/LadybirdBrowser/ladybird/pull/86)
Multiple APIs have moved from the DOM Parsing and Serialization spec to
HTML.

Previously, no event was fired on middle click. This change also allows
the UI to open a link in a new tab on middle click.
(cherry picked from commit 31d7fa244232c2a2239dbf6017ba9e3dd191ec2e)
This simulates click of the middle mouse button, which is necessary for
testing whether the `auxevent` fires correctly.

Apple Clang doesn't like this, rather than waiting for their version of

work around the issue.
Fixes#186.

This fixes https://html5test.com/ as previously an exception was being
thrown after trying to access this attribute which would then result in
a popup about the test failing (and none of the test results being
shown).

Now that EasingStyleValue is a lot nicer to use, there isn't much reason
to keep TimingFunction around.

manually amended with the output of `git clang-format master`)
The values aren't that complex, so it doesn't make much sense to have a
dedicated generator for them. Parsing them manually also allows us to
have much more control over the produced values, so as a result of this
change, EasingStyleValue becomes much more ergonomic.

This fixes an issue where entering EXAMPLE.COM into the URL bar in the
browser would fail to load as expected.
(cherry picked from commit 1a4b042664f8fddbfa70f009c5873b1f8575bf0b)
Previously, part of the procedure we used to sanitize URLs entered via
the command line would check the host against the public suffix
database. This led to some valid, but not publicly accessible URLs
being treated as invalid.
