Original commit message from CVS: * ext/alsa/Makefile.am: * ext/alsa/gstalsa.c: (gst_alsa_detect_rates), (gst_alsa_detect_formats), (get_channel_free_structure), (caps_add_channel_configuration), (gst_alsa_detect_channels), (gst_alsa_probe_supported_formats): * ext/alsa/gstalsa.h: * ext/alsa/gstalsasink.c: (gst_alsasink_getcaps): Refactor and improve caps probing code: probe signedness when we probe the supported formats/widths; set endianness to the one we actually probed for (ie. cpu endianness). * ext/alsa/gstalsasrc.c: (gst_alsasrc_init), (gst_alsasrc_getcaps), (gst_alsasrc_close): * ext/alsa/gstalsasrc.h: Implement caps probing for alsasrc.
