Whole frame windows

[Nick Roberts <nickrob@snap.net.nz>]

I know there's a feature freeze, but how about something like below to
expand a window to the whole frame and back?  It's handy for many window
configurations like gdb-ui where the stack trace, for example, doesn't
always fit in the space available.  Eclipse has a feature like this, when
you double click on the window tab.

Seems pretty harmless to me and any release must be a long way away.
