Original commit message from CVS: * tests/check/Makefile.am: * tests/check/elements/fakesink.c: (chain_async_buffer), (chain_async), (chain_async_return), (GST_START_TEST), (fakesink_suite), (main): Added fakesink test that checks prerolling and clipping behaviour. * tests/check/gst/gstutils.c: (GST_START_TEST): Make check run faster so that buildbots don't timeout.
