b4a29113e4 Documentation: Add a guide for setting up Qt Creator 
This was already in video form, but I figured it might be nice to
have this here as well, to make it easier to discover.

41d2a0e9f7 Kernel: Dequeue dying threads from WaitQueue 
If a thread is waiting but getting killed, we need to dequeue
the thread from the WaitQueue so that a potential wake before
finalization doesn't happen.

AK: Make min/max behave like the STL for equivalent inputs (#2976) 
min(a, b) now returns a if both are equivalent.
max(a, b) now returns a if both are equivalent.

8dea25d974 UserspaceEmulator: Add support for UNIX signals :^) 
The emulator will now register signal handlers for all possible signals
and act as a translation layer between the kernel and the emulated
process.

To get an accurate simulation of signal handling, we duplicate the same
trampoline mechanism used by the kernel's signal delivery system, and
also use the "sigreturn" syscall to return from a signal handler.

Signal masking is not fully implemented yet, but this is pretty cool!

a9fb317a63 Build: Clang should get -Werror too 
I accidentally removed it in a619943001 and #3002 only restored
it for gcc.

adb83d3adc AK: Decorate AK::TriState with [[nodiscard]] 
TriState is another type of return code, it's value should always be
observed.

3319803bd9 AK: Decorate atomic compare exchange operations with [[nodiscard]]

9ef834384d LibGUI: Use set_cursor() in TextEditor::set_document() 
Instead of setting m_cursor directly to reset the cursor position,
TextEditor::set_document() now uses set_cursor() which will call cursor
change callback functions, if any.

This fixes a bug in HackStudio where the cursor information text would
not update immediately after changing the active TextDocument, even
though the cursor is always visibly being reset to 0, 0.

e2b4fef6c7 LibWeb: Specialize hit testing for text cursor purposes 
The text cursor follows slightly different "intuitive" rules than the
regular hit testing. Clicking past the right edge of a text box should
still "hit" the text box, and place the cursor at its end, for example.

We solve this by adding a HitTestType enum that is passed to hit_test()
and determines whether past-the-edge candidates are considered.

fa625a2690 AK: Decorate AK::OwnPtr::leak_ptr() with [[nodiscard]] 
We should always leak to an observed variable, otherwise
it's an actual leak. This is similar to AK::RefPtr::leak_ref()
which is also marked as [[nodiscard]].

fa666f6897 Kernel: Use Userspace<T> for the futex syscall 
Utilizie Userspace<T> for the syscall argument itself, as well
as internally in the SC_futex_params struct.

We were double validating the SC_futex_params.timeout validation,
that was removed as well.

5a984b811c Build: Re-enable -Werror when building with GCC 
It looks like PR #2986 mistakenly removed this from both the
Clang and GCC CXX_FLAGS, when the intention seems to have been
to only disable it for Clang.

ea3ee4f3f3 Kernel: Decorate KResultOr with [[nodiscard]] to catch misbehaving callers 
The [[nodiscard]] decorator enables us to have the compile emit a
warning anytime the decorated type or function's return value isn't
observed. It's very useful for catching error checking bugs in systems
which use C style error handling.

e8c9b5e870 Kernel: Make Inode::directory_entry_count errors observable. 
Certain implementations of Inode::directory_entry_count were calling
functions which returned errors, but had no way of surfacing them.
Switch the return type to KResultOr<size_t> and start observing these
error paths.
