8ed06789ed New debug printing facilities. 
- Can now register a userspace file descriptor as the output for kernel
  print statements through kprintf()
- Can set logging levels for debug print messages, which are separate
  from kernel log events and meant to be more readily visible. Log
  events are recorded in a buffer to be viewed later, though nothing
  actually using logging at the moment.
- Serial output is disabled by default now. You can enable it yourself
  by appending the logtoserial argument to the kernel on boot.

bba242dd62 Add a testing framework. 
This is an automated system by which we boot qemu headless and use the
serial line to capture output from a testing application that is started
on bootup, running with the VGA terminal shell. This might be expanded
to boot to the graphical display within VNC and perform more advanced
tests with the Python shim using a VNC module for Python; we'll see.

339b82e10c [massive commit] Userspace terminal. 
Completely removes:
* The kernel terminal (both VGA and graphical)
* The kernel ANSI parser (obviously)
* kgets() function
* Dozens of other functions that were made useless

Adds:
* Userspace terminal that should work (relatively) well
* Keyboard device driver (implemented with a "pipe" object)
* Stabalized interrupt interface
* `clear` uses the c library
* All panic screens and kprintf() output goes to the serial line ONLY
* The kernel boots directly into /bin/terminal (no arguments, unless you
  want to add them (such as -f))

c0f45e0b7f VESA mode switching support. 
BIOS execution is provided through the `v8086` module, which provides
software emulation of an 8086 processor. It is not currently working
with some BIOSes and may (read: probably will be) replaced with another
emulator (x86emu comes to mind) at some point in the near future. In the
meantime, the default video mode for QEMU works with this and it's
enough to get us on real VESA instead of fake VBE. The `bochs` module
will be renamed in a future commit. Userspace programs have been
adjusted to work at bitrates other than 32 *POORLY*. If you write pixels
left-to-right, they should work fine. They only work with 24-bpp
otherwise, and then you need to be careful of what pixels you are
writing when, or you will overwrite things in other pixels.

You may pass a commandline argument like the following to set display
modes:

  vid=vesa,1024,768

Or for stranger modes under QEMU or Bochs, use the bochs VBE
initializer:

  vid=bochs,1280,720

Note that the address of the linear framebuffer is still found via
hackish probing instead of PCI or trusting the VBE information, so if
you have things in the wrong memory ranges (0xE0000000+), be prepared to
have them get read.

Once again, this entire commit is a massive hack. I am happy that it
worked, and I will continue to make it less hacky, but in the meantime,
this is what we've got.

Happy holidays.

021585e9ef [misc] Massive improvements to process handling 
- Free process resources when a process exits (reaped in next process
  cycle; should probably reap after a wait() or something)
- Free process struct after wait()
- Fix page allocation
- Fix fork() return value for child process (attempted to write to an
  invalid point in kernel-stack memory)

We shouldn't be triple faulting randomly anymore!

Continue investigating the fork() return value, as there was a bugged
return at some point during executon of a test run of thrash-process.

- Makes it far easier to include more console drivers in the kernel,
  though this will be terribly redundant in the future.
- Actually check for video graphics modes before attempting to draw the
  mouse cursor.

8f07b1a417 [mem/task] Fix broken handling of page faults 
The method I was using resulted in a loop of halts attempting
to remove process 0 from the thread queue if the kernel itself
was doing the faulting. This should fix that. Once there are
no more processes available, we bail out and call STOP.
