52e194c543 HackStudio: Add ability to set hardware watchpoints on variables 
We can now add a watchpoint to a variable by right clicking on it
in the variable view, and selecting add watchpoint. To remove a
watchpoint, the exact same action is repeated, except it will now say
remove watchpoint.

e0be8a3f59 HackStudio: Don't crash when invalid file is requested to be opened 
Previously, if the running debugger asked for HackStudio to open
an invalid file, it would crash trying to switch to it. Now it will
just continue without switching the editor.

7a1396f509 LibDebug: Implement ability to set watchpoints 
Now we can set hardware watchpoints for our variables! :^)
These watchpoints will be automatically removed when
they go out of scope.

3123ffb19d Kernel: Add ptrace commands for reading/writing the debug registers 
This adds PT_PEEKDEBUG and PT_POKEDEBUG to allow for reading/writing
the debug registers, and updates the Kernel's debug handler to read the
new information from the debug status register.

c84107a1ab Kernel: Add boot argument to disable the UHCI Controller 
Helps with bare metal debugging, as we can't be sure our implementation
will work with a given machine.

As reported by someone on Discord, their machine hangs when we attempt
the dummy transfer.

It's silly to waste review cycles on spelling, so let's ask that

81daca5dd7 LibC: Implement assignment suppression for vsscanf 
The vsscanf library function lets the user skip assigning
parsed values to the arguments, e.g. with %*c - even though
a character is scanned it is not assigned to one of the
arguments.

The figlet port uses this. With this patch the port is actually
usable.

5c924d395f Meta: Disable discord notifications timeout 
Since some builds can take even longer than 1 hour
(for example: f033416893)
this commit just increases the timeout to be github's
own workflow timeout (effectively disabling it) and just
lets github handle it instead.

cf13fa57cd Kernel: Allow system calls from the dynamic loader 
Previously the dynamic loader would become unused after it had invoked
the program's entry function. However, in order to support exceptions
and - at a later point - dlfcn functionality we need to call back
into the dynamic loader at runtime.

Because the dynamic loader has a static copy of LibC it'll attempt to
invoke syscalls directly from its text segment. For this to work the
executable region for the dynamic loader needs to have syscalls enabled.

d7978a3317 Toolchain: Enable -fexceptions and build a separate libstdc++ for the kernel 
This enables building usermode programs with exception handling. It also
builds a libstdc++ without exception support for the kernel.

This is necessary because the libstdc++ that gets built is different
when exceptions are enabled. Using the same library binary would
require extensive stubs for exception-related functionality in the
kernel.
