b2dd12daac LibC: Change putenv (and getenv) to not copy, but directly return the environ values.
This is in keeping with how putenv should function. It does mean that
the shell's export command now leaks, but that's not a difficult fix.

Contributes to #29.

3cba2a8a78 Kernel: Add a beep() syscall that beeps the PC speaker.
Hook this up in Terminal so that the '\a' character generates a beep.
Finally emit an '\a' character in the shell line editing code when
backspacing at the start of the line.

43604bf71a LibC+Shell: Make system() actually work.
system() will now fork off a child process and execute the command via
/bin/sh -c. There are probably some things to fix here, but it's a start.

ba7364b43b Shell: Move line editing to a separate class.
To be clear, there isn't really any line editing yet. But there is
going to be, so let's have it in its own class.
