SystemTheme.h:81:1: error: 'SystemTheme' defined as a struct here but previously declared as a class; this is valid, but may result in linker errors under the Microsoft C++ ABI

9c6f7d3e7d LibGUI: Actually store the column in MultiView::set_model_column()
We were only forwarding the value to the subviews, but not storing it
in m_model_column. This would cause MultiView::model_column() to return
the wrong value.

Thanks to Daniel Bos for spotting this! :^)

074d935c6e AK, LibGfx, LibGUI: Initialize various variables to zero.
The not initialized variables can lead to compiler warnings that
become errors with the -Werror flag.

cbf2881bf7 LibThread: Fix destroying background actions
In the old model, before bc319d9e88, the parent
(the background thread) would delete us when it exits (i.e. never), so we had to
keep track of our own refcount in order to destroy ourselves when we're done.

With bc319d9e88, the parent keeps additional
reference to us, so:
* There should be no need to explicitly ref() ourselves
* The unref() would not get rid of the last reference to us anymore

The latter is why all the BackgroundAction's were getting leaked. Fix this by
simply unparenting ourselves from the background thread when we're done.

We'll enable it once ColumnsView is less crashy. :^)

90c4e6b000 LibThread: Post the completion callbacks to the *current* event loop
FilePicker was not showing thumbnails correctly because once each
thumbnail rendering BackgroundAction completed, it posted a deferred
invocation event to the *main* event loop.

Since FilePicker runs in a nested event loop, those completion
callbacks never ran until it was too late and the FilePicker was gone.

2ad405c789 LibGUI: Complain in SortingProxyModel::data() if map_to_target() fails
There is some sort of issue with using a SortingProxyModel together
with ColumnsView. This is a workaround to allow FilePicker to use a
MultiView for now, but this needs to be fixed separately somehow.

1b2b35cc40 LibGUI: Add a MultiView widget, based on FileManager's "DirectoryView"
A MultiView is a combination of ItemView, TableView and ColumnsView
smashed into a single widget. You can switch between the view modes
by calling MultiView::set_view_mode().

Note that MultiView inherits from StackWidget, not AbstractView.
That's purely for practical reasons, although I'm not entirely sure
if there would be some benefit to having it inherit from AbstractView.

bc64f8c502 LibGUI: Make AbstractView::set_model() take a RefPtr<Model>
Let's face it: Taking RefPtr<T>&& arguments is obnoxious and puts too
much unnecessary burden on the caller.

ee3811dee8 TextEditor: Pledge "thread" since it's needed by GUI::FilePicker
This is a little bit awkward since it's only used for generating
thumbnails on a background thread and it's not like I care about
thumbnails very much in a text editor, but for now let's just pledge
"thread" so I can get on with the thing I wanted to get on with.

ab6f694905 WindowServer+LibGUI: Allow changing a window's base size and increment
Previously it was only possible to change these window attributes when
creating a new window. This patch adds an IPC message that allows you
to change them at runtime.

30a8991dbf Kernel: Make Region weakable and use WeakPtr<Region> instead of Region*

79576f9280 Kernel: Clear the region lookup cache on exec()
Each process has a 1-level lookup cache for fast repeated lookups of
the same VM region (which tends to be the majority of lookups.)
The cache is used by the following syscalls: munmap, madvise, mprotect
and set_mmap_name.

After a succesful exec(), there could be a stale Region* in the lookup
cache, and the new executable was able to manipulate it using a number
of use-after-free code paths.

85307dd26e Kernel: Don't use references or pointers to physical addresses
Now the ACPI & PCI code is more safer, because we don't use raw pointers
or references to objects or data that are located in the physical
address space, so an accidental dereference cannot happen easily.
Instead, we use the PhysicalAddress class to represent those addresses.

bb73802b15 CPU: Use the new interrupt components
Now we use the GenericInterruptHandler class instead of IRQHandler in
the CPU functions.
This commit adds an include to the ISR stub macros header file.
Also, this commit adds support for IRQ sharing, so when an IRQHandler
will try to register to already-assigned IRQ number, a SharedIRQHandler
will be created to register both IRQHandlers.
