API: Add buffer clipping function for raw audio buffers. Fixes #456656.
Original commit message from CVS: * docs/libs/gst-plugins-base-libs-sections.txt: * gst-libs/gst/audio/audio.c: (gst_audio_buffer_clip): * gst-libs/gst/audio/audio.h: * tests/check/libs/audio.c: (GST_START_TEST), (audio_suite): API: Add buffer clipping function for raw audio buffers. Fixes #456656. Also add deprecation guards for gst_audio_structure_set_int() to the header.
