Remove old, unnecessary functions.

1. These aren't even in the right file.
2. These aren't even used, and when I tried running one of them in my
current setup, everything went crazy.
3. While I appreciate the idea of emacs being able to resize itself,
it doesn't work in a terminal, and also it doesn't even work that well
under a window system, where really there should be another way of
sizing the window appropriately (e.g. xmonad, Divvy).

So: begone, ye functions.
