Why in gud-common-init?  Why not in gdb-many-windows?

The other method of invoking GDB, gdb-gud, does not change the window
configuration in any significant way, and never restored window
configuration for as long as the old "M-x gdb" existed.  So I think we
can limit this feature to gdb-many-windows, which _does_ change the
window configuration in dramatic ways.
