gst-libs/gst/riff/riff-media.c: Correctly support 4, 6 and 8 channels with normal PCM and float wav files.
Original commit message from CVS: * gst-libs/gst/riff/riff-media.c: (gst_riff_create_audio_caps): Correctly support 4, 6 and 8 channels with normal PCM and float wav files. Fix the depth and signedness calculation in extensible wav files and also handle 1, 2, 4, 6, 8 channels here when a file without channel mask is found. Add support for float, alaw and mulaw in extensible wav files. This allows correct playback of all but 5 files from http://www-mmsp.ece.mcgill.ca/Documents/AudioFormats/WAVE/Samples.html (gst_riff_create_audio_template_caps): Add voxware and float formats to the template caps.
