76e34968fa Demos: Setup window icon for Mouse demo 
The icon was set in the launcher, and the About dialog, but was
missing form the actual window.

e4b068aec5 UserspaceEmulator: Fix buggy IDIV instructions 
These were not doing mashing together the signed double-size results
correctly and lost bits in the signed/unsigned casting process.

9e6d002660 UserspaceEmulator: Fix buggy IMUL instructions 
These were not recording the higher part of the result correctly.
Since the flags are much less complicated than the inline assembly
here, just implement IMUL in C++ instead.

70cb4491d7 AK: Use "signed char" as the opposite of "unsigned char" 
I totally forgot about the C++ basics here. There are three distinct
types: "char", "signed char" and "unsigned char". Whether "char" is
signed or unsigned is implementation specific.

02882d5345 UserspaceEmulator: Add single-operand MUL and DIV instructions 
These are the unsigned variants. Signed variants sold separately.

30d512144e UserspaceEmulator: Implement the BSF and BSF instructions 
BSF maps nicely to __builtin_ctz(), but for BSR we have to bust out
some inline assembly to get exactly what we want.

a98d960ad4 Taskbar: Use Name from .af file as tooltip 
With this, System Monitor has "System Monitor" instead of
"SystemMonitor" as tooltip, matching the app's title bar
and menu bar title.

Same for File Manager and Text Editor.

82c38f6fdf WindowServer: Decide on a window title before measuring its width 
If we add "(Not responding)" to the title of an unresponsive window,
the title rect needs to be wider or we'll have text-on-stripes.

Thanks to @SharpOB for reporting this bug!

8ec8ec8b1c Kernel: Remove special-casing of sys$gettid() in syscall entry 
We had a fast-path for the gettid syscall that was useful before
we started caching the thread ID in LibC. Just get rid of it. :^)

the inputs.

51b2b0d5e5 WindowServer: New title bar vars for themes 
The theming system can now control title bar height, title button
size, title stripe color and the title text shadow color.
The implemented theme metrics system could be later extended to LibGUI
to allow themes to change widget padding, border width, etc.

c969b8390d Kernel: Make all 6 VirtualConsoles available via shortcut 
Add all 6 shortcuts even if the switch between VirtualConsoles is
currently not available in the graphical console.

Also make the case statement more compact.

d8fa8c5f82 Kernel: Ensure there are all VirtualConsoles properly initialized 
It is possible to switch to VirtualConsoles 1 to 4 via the shortcut
ALT + [1-4]. Therefor the array of VirtualConsoles should be guaranteed
to be initialized.

Also add an constant for the maximum number of VirtualConsoles to
guarantee consistency.

971a42a816 Kernel: Make the VirtualConsole index const unsigned instead of unsigned

behavior

df58ea808e UserspaceEmulator: Skip freed mallocations in reachability scan 
Something being reachable from a freed mallocation doesn't make it
actually reachable.

Thanks to Jonas Bengtsson for spotting this! :^)

27aa2e5841 UserspaceEmulator: Reset malloc backtrace on mallocation reuse 
If a previously-freed malloc chunk is reused, forget any old backtraces
and save a new malloc backtrace.

869a3e2cf3 LibC: Notify UserspaceEmulator about BigAllocationBlock mallocs 
We were forgetting to inform UE about these, which caused it to believe
subsequent calls to free() were invalid.

f591157eb8 WindowServer: Fix picking new active window after destroy 
We need to mark windows as destroyed and not consider them
when picking a new active window. Fixes lost focus after
closing some windows.

603c17262c WindowServer: Fix traversing modal stack 
When walking the modal window stack upwards, we need to check if
the top modal window is still a descendant of the window that
the parent is blocked by. Fixes not all windows being brought to
the front when trying to active a parent in the middle of the
modal window stack.

1dcc21d32e UserspaceEmulator: Include malloc/free backtraces in UAF logs :^) 
When catching a use-after-free, we now also print out the backtraces
for where the memory was allocated, and for where it was freed.

This will be extremely helpful for debugging.

441918be7e UserspaceEmulator: Capture backtraces of malloc/free events 
This lets us show backtraces for each leaked mallocation in the leak
report at the end. :^)

f6584bfc36 UserspaceEmulator: Implement very basic leak checking :^) 
Upon exit, the emulator will now print a leak report of any malloc
allocations that are still live and don't have pointers to their base
address anywhere in either another live mallocation, or in one of the
non-malloc-block memory regions.

Note that the malloc-block memory region check is not fully functional
and this will work even better once we get that fixed.

This is pretty cool. :^)
