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 .

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.

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.
