IconView now responds to the editing key (F2) if the view is editable.
It does feel a little bit weird to have content_rect() return the text
rect for an item, and not the whole item rect. This internal API could
probably be better.
This enables inline editing of filenames for table views, where this is
already supported. More work in LibGUI will be required to support the
feature in icon and columns views.
With this commit, <AK/Format.h> has a more supportive role and isn't
used directly.
Essentially, there now is a public 'vformat' function ('v' for vector)
which takes already type erased parameters. The name is choosen to
indicate that this function behaves similar to C-style functions taking
a va_list equivalent.
The interface for frontend users are now 'String::formatted' and
'StringBuilder::appendff'.
Don't require clients to templatize modrm().read{8,16,32,64}() with
the ValueWithShadow type when we can figure it out automatically.
The main complication here is that ValueWithShadow is a UE concept
while the MemoryOrRegisterReference inlines exist at the lower LibX86
layer and so doesn't have direct access to those types. But that's
nothing we can't solve with some simple template trickery. :^)
m_cached_code_end points at the first invalid byte, so we need to
update the cache if the last byte we want to read points at the
end or past it. Previously we updated the cache 1 byte prematurely in
read16, read32, read64 (but not in read8).
Noticed by reading the code (the code looked different from read8() and
the other 3). I didn't find anything that actually hit this case.
This is useful for reading and writing doubles for #3329.
It is also useful for emulating 64-bit binaries.
MemoryOrRegisterReference assumes that 64-bit values are always
memory references since that's enough for fpu support. If we
ever want to emulate 64-bit binaries, that part will need minor
updating.
Fixes keyboard increment/decrement of SpinBox values.
After PR #2412 the TextBox class started not propagating arrow key
events to the parent widgets because it handles them itself now.
It also added two new events for these arrow keys, so use them instead
in SpinBox.
With this patch, we now enforce basic same-origin policy for this one
<iframe> attribute.
To make it easier to add more attributes like this, I've added an
extended IDL attribute ("[ReturnNullIfCrossOrigin]") that does exactly
what it sounds like. :^)
Getting ready for some extremely basic same-origin policy stuff,
this initial implementation simply checks that two origins have
identical protocol, host and port.
Empty string is extremely common and we can avoid a lot of heap churn
by simply caching one in the VM. Primitive strings are immutable anyway
so there is no observable behavior change outside of fewer collections.
Two things I hate about C++:
1. 'int', 'signed int' and 'unsigned int' are two distinct types while
'char, 'signed char' and 'unsigned char' are *three* distinct types.
This is because 'signed int' is an alias for 'int' but 'signed char'
can't be an alias for 'char' because on some weird systems 'char' is
unsigned.
One might think why not do it the other way around, make 'int' an
alias for 'signed int' and 'char' an alias for whatever that is on
the platform, or make 'char' signed on all platforms. But who am I
to ask?
2. 'unsigned long' and 'unsigned long long' are always different types,
even if both are 64 bit numbers.
This commit fixes a few bugs that coming from this.

This function is not avaliable in the kernel.
In the future it would be nice to have some sort of <charconv> header
that does this for all integer types and then call it in strtoull and et
cetera.
The difference would be that this function say 'from_chars' would return
an Optional and not just interpret anything invalid as zero.
