Original commit message from CVS: * docs/libs/gstreamer-libs-sections.txt: API: addition: gst_adapter_take_buffer() * libs/gst/base/gstadapter.c: (gst_adapter_push), (gst_adapter_peek), (gst_adapter_take), (gst_adapter_take_buffer), (gst_adapter_available_fast): * libs/gst/base/gstadapter.h: Prepare for optimizing the hell out of this hugely inefficient piece of code. Added gst_adapter_take_buffer() so we can at least start thinking about subbuffering and merging. Added some comments. * tests/check/Makefile.am: * tests/check/libs/adapter.c: (GST_START_TEST), (gst_adapter_suite), (main): Added GstAdapter check.
