Support both GTK+ 1.2 and GTK+ 2.x in single configure scripts.
GTK+ 2.x is used unless --with-gtk2=no is given.
If you have no gtk1 or gtk2 devel packages, use configure.in-gtk1
or -gtk2 and do autoreconf.
There was a change in the mixer (enumerates) and I forgot to change
rmedigicontrol, too. But this patch removes
"snd_ctl_elem_value_get_enumerated()" for the rme32/rme96 cards now.
The patch is only tested with a rme32 card here.
