gst/real/: Added RealAudio wrapper elementfactory.
Original commit message from CVS: Patch by: Lutz Mueller <lutz@topfrose.de> * gst/real/Makefile.am: * gst/real/gstreal.c: (plugin_init): * gst/real/gstrealaudiodec.c: (gst_real_audio_dec_chain), (gst_real_audio_dec_setcaps), (gst_real_audio_dec_init), (gst_real_audio_dec_base_init), (gst_real_audio_dec_change_state), (gst_real_audio_dec_finalize), (gst_real_audio_dec_set_property), (gst_real_audio_dec_get_property), (gst_real_audio_dec_class_init): * gst/real/gstrealaudiodec.h: Added RealAudio wrapper elementfactory. Modified structures so it can also work on x86_64 using the adequate .so .
