Kernel+LibC: Add a DebugLogDevice that forwards everything to I/O port 0xe9.
...
This is then used to implement the userspace dbgprintf() in a far more
efficient way than what we had before. :^)

More compat work.
...
Move syscall to int 0x82 since using int 0x80 was kinda prone to fork bombs
when building things on Linux. :^)

Some compat work towards making GCC's libstdc++ build.

LibC: Implement various things to get GNU bc building and running.
...
Looks like that's all we needed, and bc now runs. :^)

LibC: Add some things needed to build GNU bc.
...
This patch adds vprintf(), sig_atomic_t, random() and strdup().
bc doesn't build yet, but it will.

Start refactoring the windowing system to use an event loop.
...
Userspace programs can now open /dev/gui_events and read a stream of GUI_Event
structs one at a time.
I was stuck on a stupid problem where we'd reenter Scheduler::yield() due to
having one of the has_data_available_for_reading() implementations using locks.

This is really neat. :^)

Add some simple write buffering to LibC's stdio.
...
Plumb it all the way to the VirtualConsole. Also fix /bin/cat to write()
the whole chunks we get from read() directly to stdout.

Miscellaneous compat work while seeing if GNU coreutils would build.

More work towards getting bash to build.
...
Implemented some syscalls: dup(), dup2(), getdtablesize().
FileHandle is now a retainable, since that's needed for dup()'ed fd's.
I didn't really test any of this beyond a basic smoke check.

Lots of minor compat stuff while seeing if bash would build.

We're quite far from bash building, but we'll get there eventually!

Add getpwent() family of functions to LibC.

Also add a little /etc/passwd database. There's just me in there.

Enough compatibility work to make figlet build and run!
...
I ran out of steam writing library routines and imported two
BSD-licensed libc routines: sscanf() and getopt().
I will most likely rewrite them sooner or later. For now
I just wanted to see figlet running.

A bunch of LibC boilerplate stuff added while trying to get figlet to build.
