As Oscar indicated, Emacs 24.4 has this.

You can also toggle maximization (but not fullscreen), on all
platforms in all Emacs versions (starting with Emacs 20), using
library `frame-cmds.el', which you can get from Emacs Wiki (or
MELPA), http://www.emacswiki.org/emacs-en/download/frame-cmds.el

There you will find commands `maximize-frame' and `restore-frame',
aka `toggle-max-frame'.  From the doc string:

,----
| Toggle maximization of FRAME horizontally, vertically, or both.
| Reverses or (if restored) repeats the effect of the Emacs maximize
| commands.  Does not restore from maximization effected outside Emacs.
| 
| With no prefix arg, toggle both directions.
| With a non-negative prefix arg, toggle only vertically.
| With a negative prefix arg, toggle horizontally.
| 
| When toggling both directions, each is toggled from its last maximize
| or restore state.  This means that using this after
| `maximize-frame-horizontally', `maximize-frame-vertically',
| `toggle-max-frame-horizontally', or `toggle-max-frame-vertically' does
| not necessarily just reverse the effect of that command.
`----

If you use a standalone minibuffer frame then "maximizing" another
frame leaves room for the minibuffer frame; it does not occlude it.

All of the commands in the library work with all Emacs versions
(starting with Emacs 20).
