Fix for NEWSEGMENT bug in GstBaseParse

GstBaseParse from audioparsers (aacparse, ac3parse, amrparse, flacparse) sends
the wrong start and position time to the NEWSEGMENT event.

In my case, where I've derived a video parser from GstBaseParse, this causes
the first frame of video to be dropped by filesink:

gst-launch filesrc location=video.ext ! extparse ! filesink location=output.raw

I've attached a patch which fixes this bug, at least for me. Please review it
though as I am fairly new to GStreamer and don't fully understand segments and
events yet.
