4c44c96bc6 LibDebug: Unbreak LineProgram::parse_source_directories() 
This regressed with ac9f6fd1f8 where
we switched to using InputMemoryStream.

ddab7ab693 Kernel: Store TTY's foreground process as a WeakPtr<Process> 
This ensures that we don't leave a stale PGID assigned to the TTY after
the process exits, which would make PID recycling attacks possible.

b3d1a05261 Refactor: Expose const_cast by removing ByteBuffer::warp(const void*, size_t) 
This function did a const_cast internally which made the call side look
"safe". This method is removed completely and call sites are replaced
with ByteBuffer::wrap(const_cast<void*>(data), size) which makes the
behaviour obvious.

ac9f6fd1f8 LibDebug: Use InputMemoryStream instead of BufferStream.

7e6fbef8db Kernel: Partial usage of Userspace<T> for the poll syscall 
This change mostly converts poll to Userspace<T> with the caveat
of the fds member of SC_poll_params. It's current usage is a bit
too gnarly for me to take on right now, this appears to need a lot
more love.

In addition to enlightening the syscall to use Userspace<T>, I've
also re-worked most of the handling to use validate_read_and_copy
instead of just directly de-referencing the user pointer. We also
appeared to be missing a re-evaluation of the fds array after the
thread block is awoken.

the thread from the WaitQueue so that a potential wake before
finalization doesn't happen.

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!

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]].
