This adds a ".profile" extension to perfcore files written by the
Kernel. Also, the process name is now visible in the perfcore filename.
Furthermore, this patch adds error handling for the case where the
filename generated by the Kernel is already taken. In that case, a digit
will be added to the filename (before the extension).
This also adds some more error logging to dump_perfcore().
This commit makes LibRegex (mostly) capable of operating on any of
the three main string views:
- StringView for raw strings
- Utf8View for utf-8 encoded strings
- Utf32View for raw unicode strings
As a result, regexps with unicode strings should be able to properly
handle utf-8 and not stop in the middle of a code point.
A future commit will update LibJS to use the correct type of string
depending on the flags.
This is trivial, and makes it easier to get the code point compared to
the previous `.code_points()[index]` (which was not actually checked
for in-bounds length).
There is still an offset to consider, a zero-length view is very
different from a nonexistent string :P

Widget::is_visible_for_timer_purposes needs to also consult with the
base implementation, which ultimately checks the owning Window's
visibility and occlusion state. Widget::is_visible merely determins
whether a widget should be visible or not, regardless of the window's
state.
Fixes#8825
We were re-rendering areas that were considered transparency areas even
though they weren't transparency areas or were occluded by opaque
areas.
In order to fix this, we need to be a bit smarter about what is above
and below any given window. Even though a window may have transparent
areas, if those are occluded by opaque window areas on top they are
not actually any areas that should be rendered at all. And the opposite
also applies, opaque window areas for windows below that are occluded
by transparent areas, do need to be rendered as transparency. This
solves the problem of unnecessary transparency areas.
The other problem is that we need to know what areas of a window's
dirty rectangles affect other windows, and where. Basically any
opaque area that is somehow below a transparent area that isn't
otherwise occluded, and any transparent area above any other window
area (transparent or opaque) needs to be marked dirty prior to
composing. This makes sure that all affected windows render these
areas in the correct order. To track these, we now have a map of
affected windows and the rectangles that are affected (because not all
of that window's transparency areas may be affected).
This implements a simple bootloader that is capable of loading ELF64
kernel images. It does this by using QEMU/GRUB to load the kernel image
from disk and pass it to our bootloader as a Multiboot module.
The bootloader then parses the ELF image and sets it up appropriately.
The kernel's entry point is a C++ function with architecture-native
code.

This implements window stealing in WindowServer, which allows clients
to mark a window they own as 'stealable' by another client. Indicating
that the other client may use it for any purpose.
This also updates set_window_parent_from_id so that the client must
first mark its window as stealable before allowing other clients to
use it as a parent.
This transitions from synchronous IPC calls to asynchronous IPC calls
provided through a synchronous interface in LibFileSystemAccessClient
which allows the parent Application to stay responsive.
It achieves this with Promise which is pumping the Application event
loop while waiting for the Dialog to respond with the user's action.
LibFileSystemAccessClient provides a lazy singleton which also ensures
that FileSystemAccessServer is running in the event of a crash.
This also transitions TextEditor into using LibFileSystemAccessClient.
Modify constant to be half a ULP lower so our strtod also parses it
correctly. Needs to have issue associated for actually fully fixing
strtod to be correct, rather than correct-enough.
