Original commit message from CVS: * configure.ac: Depend on gstreamer-0.10.12.1. * gst/equalizer/gstiirequalizer.c (ARG_BAND_WIDTH, _do_init, ARG_GAIN, _GstIirEqualizerBand, object, _GstIirEqualizerBandClass, parent_class, gst_iir_equalizer_band_set_property, gst_iir_equalizer_band_class_init, gst_iir_equalizer_band_get_type, gst_iir_equalizer_child_proxy_get_child_by_index, gst_iir_equalizer_child_proxy_get_children_count, gst_iir_equalizer_child_proxy_interface_init, setup_filter, gst_iir_equalizer_compute_frequencies, gst_iir_equalizer_set_property, gst_iir_equalizer_get_property, plugin_init): * gst/equalizer/gstiirequalizer.h (audiofilter): * gst/equalizer/gstiirequalizernbands.c (ARG_NUM_BANDS, gst_iir_equalizer_nbands_base_init, gst_iir_equalizer_nbands_init, gst_iir_equalizer_nbands_set_property): Use new locking macros. * gst/filter/gstbpwsinc.c (bpwsinc_set_caps): Add fixme. * gst/spectrum/gstspectrum.c (SPECTRUM_WINDOW_BASE, SPECTRUM_WINDOW_LEN, gst_spectrum_init, gst_spectrum_set_property, gst_spectrum_event, gst_spectrum_transform_ip): Use new locking macros. Turn two fixed values into #defines.
