This is similar to the LibJS test data that resides in
/home/anon/js-tests.
It's more convenient than storing the test programs as raw strings
in the code.
The context menu for CatDog was shown when right clicking anywhere on
the screen because of global cursor tracking being enabled.
Also fix event not being passed by reference.
Fixes#7285
Hook the kernel page fault handler and capture page fault events when
the fault has a current thread attached in TLS. We capture the eip and
ebp so we can unwind the stack and locate which pieces of code are
generating the most page faults.

Hiding those frames doesn't really make sense. They're a major
contributor to a process' spent CPU time and show up in a lot of
profiles. That however is because those processes really do spend
quite a bit of time in the scheduler by doing lots of context
switches, like WindowServer when responding to IPC calls.
Instead of hiding these for aesthetic reasons we should instead
improve the scheduler.
Problem:
- `static` variables consume memory and sometimes are less
optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
every time the function is run.
Solution:
- If a global `static` variable is only used in a single function then
move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
`constexpr`.

It is too complex because it supports many options that are not
used by the search engine. It just makes format validation more
complicated.
Additionaly, now it's possible to have { } characters in search
engine URL (although they are not valid URL characters) :)
The WorkQueue class previously had its own inline storage functionality
for function pointers. With the recent changes to the Function class
this is no longer necessary.
Previously <AK/Function.h> also included <AK/OwnPtr.h>. That's about to
change though. This patch fixes a few build problems that will occur
when that change happens.
This changes Variant::visit() to forward the value returned by the
selected visitor invocation. By perfectly forwarding the returned value,
this allows for the visitor to return by value or reference.
Note that all provided visitors must return the same type - the compiler
will otherwise fail with the message: "inconsistent deduction for auto
return type".
Problem:
- Function local `constexpr` variables do not need to be
`static`. This consumes memory which is unnecessary and can prevent
some optimizations.
- C-style arrays are not as safe as AK::Arrays and require the user to
specify the length of the array manually.
Solution:
- Remove `static` keyword.
- Change from C-style array for AK::Array.
This modifies the error checks in VFS::open after the call to
resolve_path to ignore a null parent custody if there is no error, as
this is expected when the path to resolve points to "/". Rather, a null
parent custody only constitutes an error if it is accompanied by ENOENT.
This behavior is documented in the VFS::resolve_path_without_veil
method.
To accompany this change, the order of the error checks have been
changed to more naturally fit the new logic.
In case the write was to stderr/stdout, and it just so happened to fail
because of an issue like "the pty is gone", VERIFY() would end up
calling vout() back to write to stderr, which would then fail forever
until the stack is exhausted.
"Fixes" the issue where the Shell would crash in horrible ways when the
terminal is closed.
Instead of sprinkling the definition of the ciper suites all over the
TLS implementation, let's regroup it all once and for all in a single
place, and then add our new implementations there.
Previously lsof would crash by incorrectly parsing valid file names
that contain spaces.
For example, established TCP socket file descriptors would cause an
lsof crash:
socket:127.0.0.1:33985 / 127.0.0.1:8080 (connected)
This commit fixes the issue by not parsing for white spaces to set the
file name.
For compressed coredumps, CrashReporter's argv were in this order:
CrashReporter path --unlink
Core::ArgsParser doesn't like that at all and would immediately exit
from main(), causing the crash reporter to never display.
When reloading a page multiple times, it was also added multiple
times to the history. This commit prohibits an url to be added
twice in a row.

Previously StringBuilder would start allocating an external buffer
once the caller has used up more than half of the inline buffer's
capacity. Instead we should prefer to use the inline buffer until
it is full and only then start to allocate an external buffer.
