Refactored *_new() functions.
Original commit message from CVS: * docs/gst/gstreamer-sections.txt: * gst/gstghostpad.c: (gst_proxy_pad_do_getcaps), (gst_proxy_pad_do_setcaps), (gst_proxy_pad_set_target_unlocked), (gst_proxy_pad_dispose), (gst_ghost_pad_new_full), (gst_ghost_pad_new_no_target), (gst_ghost_pad_new), (gst_ghost_pad_new_from_template), (gst_ghost_pad_new_no_target_from_template): * gst/gstghostpad.h: Refactored *_new() functions. Templates are now used as a g_object_new() parameter. Use template in _do_getcaps() if we don't have a target. Small documentation cleanups. Added two new constructors: gst_ghost_pad_new_from_template() gst_ghost_pad_new_no_target_from_template() * tests/check/gst/gstghostpad.c: (GST_START_TEST), (gst_ghost_pad_suite): Added tests for new ghostpad instanciation functions. API additions: gst_ghost_pad_new_from_template, gst_ghost_pad_new_no_target_from_template
