7d5eb42400 Userspace keyboard handling
Kernel driver sends raw scancodes, compositor or terminal handle the
rest. Support for F* keys will be added soon, in the mean time userspace
applications can know about the status of modifiers (control, shift,
alt, and super).

Compositor actions have been changed to Alt+Left Click for move and
Alt+Middle Click for resize. I'll work on adding more mouse events once
I get them to be faster (they're annoyingly slow at the moment... I want
more accuracy and less latency).

9d84988778 Bump version number to 0.3.7
Getting close to the big 0.4.0, but I really want to fix my ATA drivers
and possibly get some CD/ISO stuff in before then.

deaa6ad513 Rough support for environment variables
- libc functions not implemented yet
- see `env` for an example of reading variables
- see `esh` for an example of how to set and maintain variables for
  sending to other applications

  Both of the above will be the basis for the libc implementation.

2eb953f1f1 Massive fixes to the EXT2 driver.
* Works with different block sizes
* Works with different inode sizes
* Tested on a real EXT2 file system made with mkfs.ext2

* MBR reading is available
* You can specify a partition with hdd=0 or hdd=1 etc.

* If you make a "real" disk image, you can get GRUB installed in
  its MBR, toss in a suitable config file, and boot right off the
  disk rather than having to use QEMU to boot the kernel or using
  some silly CDROM ramdisk nonsense.

5ce042f2d8 Deprecate VESA support.
This is in favor of bootloader-assisted mode switching. Grub has a
wonderful option we will exploit to set the video mode.

My laptop supports a couple of 32-bit video modes, which is nice,
because I'm not support 24-bit modes.

I'm not sure whether the super-sketchy video memory locator will work
in the real world, but we'll find out sometime soon.

4c67b5da84 Completely rewrote compositing engine
The compositor itself still needs work, but the compositing engine
within now does full blitting and is faster than the old method.
Transparency is now supported properly, though telling the compositor to
use it on a window will degrade performance. One terminal is usually
okay, and everything runs faster than it did before; two terminals is
pushing it; three will make you very sad. The stacking logic has also
been updated. Presumably, alpha blitting for transparent windows could
be done with SIMD instructions and be extremely fast.

All graphics libraries have also been updated to (hopefully) work
properly with alpha bits.

cea692b577 And now with more login.
* Also cleaning up some kernel logging options here.
* You can log in as local or root with passwords local and toor
* Graphical sessions are still buggy, so don't kill that terminal.

07955c83c6 Fix dozens of build warnings and other oddities.
* Finally bring syscall.h up to speed and include all syscalls in the
  syscall module of the C library.
* Remove the third-party obfuscated C demos (we have nyancat, good
  enough)
* Fix userspace apps to build without complaining about undeclared
  strtok_r by disable __STRICT_ANSI__
* Fix .eh_frame by including the proper stuff with libgcc.

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.

fb6e5d59e3 Completely rewrite rendering model for compositor.
We know longer accept DAMAGE and REDRAW commands. Instead, we just loop
and redraw everything anyway (efficiently, mind you). Pipes still have
issues when closed and various other different things.
