[CM] Snd 8.3

[Bill Schottstaedt]

Snd 8.3

CLM generators:
   added filtered-comb ("fcomb" for freeverb)
   added move-sound (runtime portion of dlocsig)
   renamed average generator to moving-average
   renamed windowed-maxamp to moving-max (dsp.scm)
   added moving-rms, moving-sum, moving-length (dsp.scm)
      overlay-rms-env (draw.scm) uses moving-rms
      Perhaps these should be built-in CLM generators.
   mfilter (dsp.scm) -- Mathews/Smith high-Q filter
     (similar to formant; another version is maxf.scm/ins)
   removed make-ppolar|zpolar (use make-two-pole|zero)
   moved ssb-fm and rmsgain.scm code to clm-ins.scm (removed rmgain.scm)
   locsig now returns a float (not a frame)

dlocsig.scm (translation to Scheme of Fernando's dlocsig.lisp)
   in CL-CLM, dlocsig.lisp and move-sound.ins now use the move-sound generator.
   mix-move-sound (extsnd.html)

green.scm (bounded brownian noise, from CLM's green.cl)

snd8.scm (backwards compatibility stuff for snd 8)

shepard-tone (sndscm.html)
agc (dsp.scm)
with-full-sound (ws.scm)
def-clm-float-struct (CL-CLM only)
fir+comb (clm.html)
removed vct-map

g_signal_connect and other such macros, and gtk_print_operation* to xg.c

merged new-icons.scm into new-buttons.scm and renamed the latter toolbar.scm
   toolbar.scm also works in gtk
