tdf#78174: toolkit: work around GCC 4.9 -Os link failure

A build with gcc (GCC) 4.9.2 20141101 (Red Hat 4.9.2-1) for 32-bit x86
fails because of these undefined symbols:

> nm --demangle workdir/CxxObject/svx/source/fmcomp/fmgridif.o | grep
 \\bWindowListenerMultiplexer::acquire
         U non-virtual thunk to WindowListenerMultiplexer::acquire()

They should probably be generated inline.  Work around by out-lining the
definition of the methods.
