5de319b816 Work on Shmem fonts 
Still need to pass sizes around to shm_* functions as a pointer rather
than the actual size so we can retreive sizes; additionally, *p = 0
should mean "we don't want to create this buffer, we only want to
access it if it exists".

db7020cbce [security] Shadow Passwords, whoami, and more 
This update includes support for shadow passwords, stored in
/etc/master.passwd, as well as support for an /etc/passwd file
containing user/uid/full name/shell associations, which are used by the
shell to get your username for display purposes, as well as by whoami
for the same reason. The login tool does not yet select the right shell
though this is planned.

* root's password is `toor` (a throwback to older times)
* local's password is `local` (because it's obvious)

Without flushing, this doesn't work properly with the terminal pipe.
Technically, this is an issue in the pipe implementation, but as that's
not technically what we're testing there's no sense having it be broken.

For the record, everything works wonderfully.

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

- 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.
