22f04f137b Relatively compliant uname() implementation
Also, sleep() as a function (implemented by way of nanosleep) and new
absolute and relative sleep system calls added to newlib.

[ci skip] I damn well know this is going to break CI.

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.

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.

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.
