Sync with my copy before wtay starts hacking...
Decided to keep the GstBuffer name through most code because it's really
messy otherwise, and it doesn't really mean much either way. Saves lots
of stupid casting. fakesrc num_buffers=N ! fakesink ends with a segfault
on EOS right now, not tracked down yet.
Original commit message from CVS:
gstinfo.[ch], cothreads.c: added initial support for -finstrument_functions
gstbin.c: removed a reference to config.h
gstbuffer.[ch]: added gst_buffer_is_span_fast(), used it in gst_buffer_span
elements/gstfilesrc.c: initial work fleshing out the event handling code
everywhere else: wrapped XML stuff in #ifndef's
