Original commit message from CVS:

(gst_amrnbdec_setcaps), (gst_amrnbdec_event), (gst_amrnbdec_chain),
(gst_amrnbdec_state_change):
* ext/amrnb/amrnbdec.h:
Fix amrnbdec, handle events, take copy from adapter since the decoder
apparently writes in the source data.
Use some _scale_int, and precalc duration.
Fix some leaks, post ERROR messages.
