9587f2d3ee Kernel: Add SharedIRQHandler class 
This class represents a shared interrupt handler. This class will not be
created automatically but only if two IRQ Handlers are sharing the same
IRQ number.

d83a3eff1f Kernel: Update Network adapter classes to use the PCI::Device class 
Those classes will inherit from the PCI::Device class, thus,
they can still implement IRQ handling.

3252a6925e LibGUI: Fix silly nullptr dereference in MessageBox::show() 
Since we take the parent object as a raw pointer, we should handle the
case where it's null.

30556a0a93 SystemMenu: Move SystemDialog into SystemMenu and remove INI config 
I probably would've done INI config removal in another commit, but it
fit well here because I didn't want to pledge wpath for SystemMenu if I
didn't need to.

Frankly, that's something that I think should be done: allow ConfigFile
to be used read-only.

6c5100b644 LibGUI: Add helper for constructing new TabWidget tabs 
This patch adds the following convenience helper:

    auto tab_widget = GUI::TabWidget::construct();
    auto my_widget = tab_widget->add_tab<GUI::Widget>("My tab", ...);

The above is equivalent to:

    auto tab_widget = GUI::TabWidget::construct();
    auto my_widget = GUI::Widget::construct(...);
    tab_widget->add_widget("My tab", my_widget);

a70cc5ca1d Kernel: Commit the entire region up front in KBuffer::copy() 
Since we know exactly how much physical memory we'll need, we might as
well commit it up front instead of letting page faults drive it.

428582e805 LibGUI: Don't require passing a parent to widget constructors 
This is a step towards using Core::Object::add<T> more, which takes
care of parenting the newly created child automatically.

d9e459293b LibCore: Add Core::Object::add<T> helper for creating child objects 
Consider the old pattern for creating a Core::Object parent and child:

    auto parent = Core::Object::construct(...);
    auto child = Core::Object::construct(..., parent);

The above was an artifact of the pre-reference-counting Object era.
Now that objects have less esoteric lifetime management, we can replace
the old pattern with something more expressive:

    auto parent = Core::Object::construct(...);
    auto child = parent->add<Core::Object>(...);

This reads a lot more naturally, and it also means we can get rid of
all the parent pointer arguments to Core::Object subclass constructors.

859c1669f9 Shell: Add basic tilde expansion 
This does not work with shell completion yet, but the basics of being
able a cd being able to expand "~" to the current user's home directory,
and "~foo" to the home directory of user "foo" is added in this commit

case that we only need to check a single character.
